Up, Up, and Away! World's largest airship lifts off for the first time

By Claire Bates, Original remarks reported and published in the Daily Mail

UPDATED: 09:00 EST, 25 June 2012 :                                                                                               BLOG Editor's comments in RED, 10 October 2012  
More than 70 years (actually, 75 years) after the Hindenburg disaster ended the golden airship era, giant blimps will take to the skies again with the launch of the world's largest inflatable craft. See : U.S. Navy, which never gave up on using them. ...  neither did the Germans, nor the Swiss, nor the Canadians nor the Russians !
The pioneering Bullet 580 is a 235 ft. long and 65 ft in diameter airship that can lift payloads of 2,000 lbs up to 20,000 feet in the air.
It was inflated this week inside the Garret Coliseum in Alabama - one of the few facilities large enough to host the ship. The process took the developers at E-Green Technologies just over six hours.
The model 580 Bullet airship is 230 ft.  in length and covered with a thin material that is 10 times stronger than steel.
The $8,800,000  (£5.5million) craft can be flown remotely or with a crew. The company plan to build a fleet of hire vehicles (leased airships) that they will rent out for between $320,000 (£200,000) and $880,000 (£550,000) a month.
Chief Executive of E-Green Technologies, Mike Lawson, said: 'It's slow enough to be used for sightseeing, large enough to carry heavy cargo and enough volume of lifting capability to be flied (flown?!) at 20,000 feet unmanned. So you have a gift of all different technologies.'
Lift is provided by a system of seven bags filled with helium, while the inner hull is full of ambient air. Hydrogen was used in the 1920s and 1930s because helium was considered too expensive at the time and still is, the price point for helium being currently 12 times the cost of hydrogen; in addition, helium is scarce, expensive, and difficult to extract and purify . Hydrogen can be made by breaking down water into its constituent molecules of hydrogen and oxygen, both useful substances, by the use, of e.g., Concentrated Solar Power OR the hydrolysis of water using on-site generation of electricity by, e.g., wave or wind power. 

How the Bullet will look in the air. The blimp will run on ALGAE FUEL --- how difficult is that to obtain ??    ... how expensive ???  Are we missing something important in this supply chain ???
The airship will cruise at a speed of 35 m.p.h. , which will allow plenty of time for sightseeing for any passengers.
A BRIEF HISTORY OF AIRSHIPS, WHICH WE CERTAINLY NEED, AS THERE    AREN'T ENOUGH NEGATIVE HISTORIES PUBLISHED                                   (Yes, we're being sarcastic!)
In 1852 the French engineer Henri Giffard made the first  engine-powered flight in a steam-powered airship. A year later the American, Dr. Solomon Andrews, created the first lighter-than- air airship. He flew one over New York city in 1865. The first fully controllable airship flight was made in 1884. The 170 foot airship La France covered 5 miles in 23 minutes with an electric motor.
The first Zeppelin was launched in 1900. These had a rigid skeleton and passenger compartment.
During WW I the Germans, French and Italians operated airships but they were abandoned by 1917 due to unreliability. Britain developed the R33 and R34 rigid airships, which flew from 1919.
The R34 was the first to make an east-to-west Atlantic crossing.           

Another desperately-needed photograph of the Hindenburg disaster was inserted here and removed by Editor

In 1929 the LZ 127 Graf Zeppelin made the first round-the-world flight.  British journalist Grace Marguerite, Lady Hay Drummond-Hay was on board and became the first woman to circumnavigate the world by air.
Airships were poorly equipped to deal with adverse weather and crashes and fatalities were common. ... rather like writing a consumer review of a 2013 automobile by road testing 1914 Fords.
By the mid-1930s Germany was the only country pursuing airships. The Hindenburg disaster in 1937, which killed 37 people was the death knell.  Why doesn't this article mention the Navy blimps that flew bravely --- and apparently unsung ---  in all conditions to keep the menace of the Nazi U-boats from our Atlantic shores. Not one single merchant ship escorted by blimps was lost to German submarines . All this does not even mention the many search-and-rescue missions flown by Navy blimps bringing comfort and assistance to torpedoed sailors adrift in the ocean.
The U.S used airships during WW2 for military purposes but post-war they have mainly been restricted to advertising and Intelligence and reconnaissance missions too numerous to recite.
The payloads are carried inside the outer envelope of the balloon, which is only one sixteenth of an inch thick yet 10 times stronger than steel. It is made from a type of Kevlar, which is the tough material used to make bulletproof vests. Mr Lawson, said: 'If you hit a hard landing, the airship is just going to kind of bounce.'
Although the airship only has a top speed of 80 MPH it can take-off and land vertically. The craft is also able to hover over an area for up to a week at a time - something neither airplanes nor satellites nor helicopters can manage.
The craft could therefore keep a close watch on oil spills like the one in the Gulf of Mexico or monitor pirates off the coast of Somalia.
It could also serve as a near space satellite for broadcast communications, missile defense warnings, weather monitoring and geophysical surveys.
In fact its first mission will be to measure moisture content in soil. It is planned for later this year, will be a joint project of NASA and Old Dominion University. Mr. Lawson said he was confident that airships had a future in the 21st century, despite their bad press in the past.
Ed. Note : Only one airship had BAD PRESS, back in 1937; it seems to be the only tune that the Media orchestra can play. Only 36 casualties, and that appears to be the only voyage or mission that the Media remember; that one used hydrogen for the lifting gas , and flew into a strong electrical storm, which I believe they were warned about, but wanted to get down to the ground at Lakehurst, New Jersey, for the publicity and impatient passengers. Duh ! Think of all the impatient passengers that sleep on the floor of airline terminals during a snow storm. Personal observation .
His business acquired '21st Century Airships' in November 2009, which was one of the world's leading airship research and development companies.
The merged firm has already built and flown 14 prototypes, but the Bullet is their first commercial craft.
'Airships have undergone surprisingly little evolution throughout their more than 150-year history, and this is what makes our E-Green proprietary designs so desirable to government and commercial customers,' he said. I suppose that the reporter has performed little research into the many types of HYBRID designs .... NOR has she read her own description (above) of the newly developed materials of which airship envelopes are constructed, NOR has she heard of KORT nozzles, or cycloidal propellers, or ducted fans, or swivel mounts, or the remotely operated airplane drones flown over Afghanistan by pilots comfortably seated in Tampa, Florida.
'Our airships are radically different designs that move beyond the performance limitations of traditional blimps or zeppelins by combing advanced technology with simple construction and the ability to fuel with algae, protecting our environment.'
Algae is the latest biofuel exciting scientists. It draws carbon dioxide from the atmosphere when it grows and when the derived fuel is burned this same CO2 is released, making the fuel theoretically zero-carbon. Algae farms can also be created using brackish and waste water or, one could use HYDROGEN as fuel, feed it into a fuel cell (what's that?) and release nothing but water vapor into the air. Hydrogen is dangerous say Hindenburg-photograph-conscious perplexed readers ? We'll bet they drove to their office this morning in an automobile carrying a fuel tank of, say, 15 gallons of petroleum product --- one of the most explosive fuels available . OR perhaps they flew to their last vacation in a 747 , passenger jet, which flies at 35,000 feet (with no way of escape) with its fuel tank full of 48,445 U.S. gallons (183,380 liters) highly flammable jet fuel .
AMTRAK, anyone ?
The Bullet also has a Water Condensate Recovery System, which reduces the need for helium replenishment. Explanation needed here !!
The Bullet's first test flights are planned for this summer and the ship will be piloted by Captain Allan Judd who has been at the helm of smaller airships since 1986.
For those thousands of journalists who seem to have missed our compilation of civilian uses of airships the first time, here is our list, apparently not-yet-as-famous as Lady GAGA  :
Non-military Applications for LTA Airships for which Remotely Operated Airships Can Provide Safe & Suitable Service
1. Sporting event video coverage
2. Law enforcement: traffic, aerial views of traffic accidents;
3. Marine mammal population census, migration patterns
4. Design-and-Build surveys for planning & construction of bridges & roads
5. Marine biology --- spotting red tides in coastal waters; monitoring the health of coral reefs
6. Fire fighting --- first-on-scene situation assessment in high rise fires, inaccessible areas, or involving hazardous materials
7. News organizations --- parades, ceremonies, sporting events, and in  situations where danger to the news crew is possible (Think "Arab Spring" ! )
8. Radioactive and toxic waste sites --- photography, sampling, and survey without risk
9. Geology --- Oil field exploration; survey of volcanic processes and sampling of lava and ejecta from eruptions, without the hazard that recently took the life of two experienced volcanologists .
10. Federal & State Forest and Wildlife Services --- tree census; lumber poaching; game and fish poaching
11. Telecommunications --- surveying & designing fiber optic cable installations
12. Meteorological observations --- measuring wind speed, air pressure and temperature, dew point, & humidity at various altitudes above ground level 
13. Hoisting communications antennas during emergency situations
14. Fishing --- spotting big game fish for sport fishing; scouting for schools of food fish for purse seining; seining schools of fish & invertebrates visible from the air, for sale as bait to both commercial and sports fishermen, responsibly increasing the harvest with a minimum of wasteful by-catch.
15. Monitoring railways, pipelines, and power lines --- a constant and ever-present safety requirement --- that can prove very difficult in overgrown areas, or results in expensive and wasteful ground-clearing  .
16. Monitoring air pollutants for measuring air quality standards .
17. Agriculture --- Precision agriculture techniques using remote sensing technology to monitor crop moisture content AND to perform no-harm seeding from the air, in which the soil does not get compacted by heavy tractors and therefore remains friable as a good seed bed with maximum germination and a larger harvestable crop. Aaaaah-h-h, at last ! Here is the one Application they seem to have heard about
18. Archaeological site mapping; correlating aerial photographs with ground level excavations and discoveries
19. Commercial aerial photography for tourist and visitors’ bureaus, yacht brokers, school programs; realtors and real estate developers;
20. "Green" non-disruptive exploration of ecologically sensitive biospheres, such as rain forests and forest canopies sheltering endangered species
21.  Lifting transmitters & receivers into the sky for maximum range.
22. Long term recording in place by meteorological instruments --             anemometers, humidity meters, thermometers, etc.
23. Air sampling for pollutants, particulates, insects, and pollen.
24. Acoustic sensors for detection of intruders, without interference by the noise of internal combustion engines
25. Detection of mines & other explosive devices [especially relevant for civilian use, detection of unexploded abandoned mines, a major cause of death and crippling injuries to children in former war zones ]
26. Thermal imaging applications                                                                                                                                                                                                                        27. Crowd control and detection devices by law enforcement agencies
... and many more, too numerous to list .

Sadly, the length, complexity, and copyright protection of articles on the manufacture of biofuels derived from algae preclude our reprinting them here . This discussion of airships does not even touch on the cost, difficulty, and environmental effects of manufacturing algae as biofuel. As our math professor used to say just before dismissing the class, "I leave the solution of that problem to the class as homework".

UNUSUAL and SIGNIFICANT TECHNOLOGY NEWS TO WATCH

THE EDITORS OF THIS BLOG SHARE AN INTEREST BOTH IN VERY LARGE SCALE ELECTRICALLY-POWERED RAILROAD MODELS AND, THRU THIS BLOG, IN THE IMPORTANT ROLE THAT LIGHTER-THAN-AIR AIRSHIPS CAN PLAY IN MANY FIELDS OF HUMAN ENDEAVOR. IT IS VERY RARE THAT THESE TWO SEEMINGLY DISSIMILAR INTERESTS SHOULD SHARE COMMON GROUND, BUT TODAY'S NEWS PROVIDES JUST SUCH A COINCIDENCE. PLEASE READ ON :  

Reprinted fom the Proceedings of the 2012 HYDRAIL Conference held in the UK :
"Stephen Kent and Jon Tutcher – University of Birmingham Presentation PDF. Stephen Kent is a Research Fellow and Jon Tutcher is a Ph.D. candidate at the Birmingham Centre for Railway Research and Education. Together, they head up the University of Birmingham team that is currently building a 10.25-inch gauge HYDROGEN-POWERED LOCOMOTIVE to be entered in this year’s IMechE (Institution of Mechanical Engineers) Railway Challenge competition."

OUR IMPRESSION : The HYDRAIL Conference has been principally conceived and executed by Stan Thompson, of Mooresville, North Carolina, a dedicated supporter of the use of hydrogen in unique and environmentally sound ways. He has built a world-wide constituency solely on the basis of his energy, the soundness of his views, and the strength of his commitment. 

BLOG COMMENTS BY HNILS@MSN.COM  :

What IS a hydrogen-powered locomotive (HYDRAIL) ... especially, a 10.25 inch gauge miniature railway locomotive ? We outlined its application to Mega-Model miniature railways in bold-face type in the lead paragraph above to call attention to this unusual application of an important new technology.

First of all .... HYDRAIL is the fascinating new concept which utilizes a fuel cell, mounted in a locomotive --- and now other modalities with a Green power requirement (it is already being installed in many new ship engine rooms because of recent Draconian restrictions by European countries on carbon emissions) --- to generate electricity for traction motors.

Second of all, "miniature railway" is the Term of Art applied to mega-scale models with a gauge greater than 7½" and 7¼", especially those operating in Great Britain . Model railways in a scale of 1 : 5.5 (10.25" gauge) are popular in England, where that scale is utilized in a substantial percentage of passenger-hauling hobby-and-leisure layouts. Our educated guess is that this large scale was chosen for this installation because it provides a good deal of room for mounting the fuel cell.

Third of all ... the fuel cell : a newly developed device which is fueled by hydrogen stored on board in a high-compression cylinder, and fed as fuel to the cell. The output of the process is electricity, used to power traction motors in the locomotive, and ... Ta-dah ! it emits only water vapor as exhaust ! This solves four major issues :

1. the diesel particulate problem (a serious health threat)

2. the carbon cycle problem : emission of carbon dioxide by internal combustion engines and its possible effect on climate change

3. geo-political problems engendered by the importation of foreign oil (and the use of domestic oil, also, as the two are essentially commingled in the logistics process, a fact often ignored by those with personal supply chain agendas), and

4. the diesel engine noise problem,

all at one swell foop .

Fuel cells offer a nifty energy solution, but one that is being accepted and adopted only very slowly by the tradition-bound railroad industry.

We sincerely hope that news of the possibilities inherent in this technology are spread among the NGO's (non-governmental organizations --- essentially non-profit organizations), Metropolitan Planning Organizations (MPO's) , and political decision-makers, as well as among the usual suspects crowd of technocrats and engineers.

FLASH ! We just (mid-afternoon, 1 October 2012) received a news bulletin that contenders in the famous Albuquerque LTA balloon race may be using hydrogen as a lifting gas for the first time, because of a world-wide shortage of helium, reflected in both availability and price. An amount needed to fill the average balloon with helium now costs $12,000; the cost to fill the same balloon with hydrogen is only $1,000, a very significant difference. If that is an accurate reflection of the situation, it will, in all likelihood, also be reflected in planning and activities for LTA dirigible airships . It will be another good reason for serious exploration of the HYDROGEN ECONOMY !
...........................................................................................................
DEDICATED READERS OF THIS BLOG WILL NOTE THAT HYDROGEN HAS BECOME THE LOGICAL LINK OF BOTH SPECIAL INTERESTS. OUR AIRSHIP UNIVERSE Blog and our ELECTRIC RAILWAYS NETWORK find an unusual but signifcant convergence in the use of hydrogen to achieve their goals. We had no way of knowing that would happen, but are delighted to note its occurrence.

WHAT ARE THEY SPENDING THIS MONEY ON ???

When we see newspaper or industry newsletter reports about a Federal contract in the hundreds of millions of dollars for a Lighter-Than-Air (LTA) airship which somehow never gets finished, it really starts the rusty neurons of my financial brain (not really well-oiled to begin with ) wondering .
What did they spend the money on ?
We heard of one instance where, after they ran out of money, one firm had nothing to show for it but an enormous hangar , which someone should name Moby Dick, after the great White Whale of Herman Melville's novel, which must have downed millions of tons of krill (look that up in your Funk & Wagnall's or OED) during its lifetime. We understand that they had trouble disposing of that huge, almost-useless structure, because the only purpose it could serve was as  ... the hangar for a gigantic airship that did not exist.
It reminds us of the stories we had heard of high technology start-up firms during the great dot-com bubble. The youngsters who ran them ("beardless striplings", one would have called them in the Age of Chivalry, sadly long gone) received millions of dollars in investment funding from hopeful Venture Capitalists. When the inevitable lawyers tried to clean up the inevitable mess of the inevitable bankruptcy proceedings, they found that the hopeful corporate officers had squandered the money they had raised on top-of-the-line designer furniture, leases of entire floors of luxury Class A real estate now lying unused and empty, Lamborghinis, and world travel by First Class Air .
Really, folks, where did the money go ?
We picture the early Henry Ford OR the early Wright Brothers, scraping along in their garages and their bicycle shops, actually building something .. something that actually moved or flew ! It may not have been perfect, it may have had many problems and faults, but the world had a new, innovative product that one could see, and that was available for inspection and improvemnt by the inventors themselves or other manufacturers and experimenters.
There exist several classes of LTA-inventor-builders, as we see it. Among them are the Good Guys like hard-working Daniel Geery in the U.S.A. and the owner of Mini-Zepp, in Switzerland, who actually have produced constructs that exist, that fly, that they can demonstrate, and that they built with a minimum of funding and a maximum of sweat equity (remember that wonderful descriptive term?) . Mini-Zepp has actually sold their real-world products to such tough, demanding no-nonsense buyers as Cambridge University, in the UK,  and the Israeli security forces... and they've accomplished this with a minimum of waste and a maximum of good design and real-world product. Ask them what they have accomplished and they can show you !
... and then there are the Mega-LTA design-and-build folks, who receive obscene amounts from various government sources and produce ... Tah-Dah! ... Vaporware.
We do understand that some of this non-productive spending and effort has been the result of Mission Creep and unrealistic specifications (... 'Well, as long as you're doing that, why don't we add on the ability to reach the Planet Saturn ? )  or initial too-hopeful, too-stringent, or politically-correct conditions and requirements imposed by an unrealistic Pentagon or Congress.
Still, how could they run out of money ??? We may never know; certainly there are some of us finance-challenged market-watchers who stare in stunned amazement at the hundreds of millions that are consumed, as if by a dollar- and pound-sterling-munching monster .
Where did the money go ?

THE IDEAL AIRSHIP : 16 CHARACTERISTICS plus ONE ARTICLE OF FAITH

Yes, we're presenting these again, because these characteristics still appear to present the best choices in every element of airship design . We wonder whether all of them have ever been combined in the design and construction of one airship, in order to take advantage of this unique transportation method.

We also believe, as a real estate lawyer might put it, that CARRYING PASSENGERS IS NOT THE HIGHEST AND BEST USE OF AIRSHIPS .

Dr. Barry Prentice, of the Airships to the Arctic Conference series, has focused his entire professional career on Supply Chain economics and methodology --- that is, trying to determine the least expensive, most reliable, most dependable approach to solving the complex supply equation . In particular, he has for many years devoted his attention to the thorniest problem facing Canada, and therefore the World : overcoming seemingly insuperable difficulties in getting food and materiel to the extraction industries and inhabitants of Canada's Far North (and, we might add in passing, all the regions of the world with similarly difficult, seemingly non-traversable terrain, such as the rain forests of Borneo, the Amazon region of Brazil, the Himalayas , and the Antarctic),  and furnishing emergency services to those regions. His conclusion, derived through his iconic Arctic Conference series, is that airships can provide this solution.

I agree ! I think that anyone who has followed the Ice Road Truckers television reality show and witnessed the ordeals of those supply chain providers will agree . In each case, airships present a much better transport method than trucks (lorries) .

We didn't say perfect : Just remember that the Perfect is the enemy of the Good :  in other words, if you wait until you have perfected a solution, the opportunity for a good solution probably will have passed . Just think of the development of the automobile. The first ones must have been dreadful to operate and to travel in. We can't wait until the airship equivalent of a four-door Cadillac sedan is developed; let's make do with the Model A Ford. BUT, given that each of the components outlined below in my list below is well-defined, let's use the best of each and begin operations. 

What I perceive is that current airship development efforts are forging ahead in the apparent hope of receiving the fabled $500,000,000 military contract at the end of the rainbow. Those firms that have gone through this cycle and then found, to their horror, that the contract is suddenly cancelled (read the news), that funding is no longer available, or that the Pentagon has changed its mind.  They then have great difficulty recovering their equilibrium --- and that's a bad position for an airship firm .   

Sometimes the best solution is to plunge in, as we have done. On the other hand, having this list of Characteristics of the Ideal Airship on hand may well prove to be a Fusion design that provides the best solution we have right now. IS ANYONE OUT THERE BUILDING THIS AIRSHIP ??? 

This BLOG lists below the Top 16 Characteristics Plus One .

       THE TOP SIXTEEN CHARACTERISTICS OF THE IDEAL AIRSHIP FREIGHTER

1. Hybrid --- designed with winglets or lifting planes to provide some of the lift, the balance of the lift provided by ...
2. ... hydrogen, and probably contained in ballonets (separate auxiliary storage spaces) , produced by ...
3. ... Concentrated Solar Power (CSP) because of the expense and other negative aspects of producing hydrogen by electrolysis and other methods .
4. This hydrogen to be used as the lifting gas ... 
5. ... and the fuel for ...
6. ... a Fuel Cell to produce ...
7. ...   electricity for the ...
8. ... electric motors driving ...
9. ... the Ducted Fans ... propellers encased in cowls for maximum effective propulsion and ...
10. ... mounted in universal swivel mounts so they can be used for
11. ... lift, by pointing them downward, and
12. ... steering, rather than using rudders, and
13. ... reverse thrust to hold the airship down onto the ground without the need for dangling ropes and a large ground crew .
14. The airships would carry detachable standard cargo containers designed for speed and convenience in loading and unloading, and aerodynamically streamlined for minimum drag ..
15. Unmanned , for safety, for convenience, to maximize the useful payload; proven by use in military applications, with minimum risk to crew or other personnel that otherwise might be aboard aboard.
16. The entire airship designed in a shape akin to the famous Deltoid Pumpkin Seed .  And ...     

THE 17th CHARACTERISTIC : AN ARTICLE OF FAITH  :  TIE THEM ALL TOGETHER WITH THE HIGHEST AND BEST USE IN MIND

17. In general, employ the Systems Approach : "Horses for Courses". That is, choose the mission as the determinative factor for the choice of type and design of transportation, rather than choosing the mode of transportation and then trying to force that use onto the airship. 

Good Luck ! BUT if the design is good, you won't need luck !

REMOTELY PILOTED AIRSHIP FOR ATMOSPHERIC TRACER

 

DEPARTMENT OF ENERGY, NATIONAL ENERGY TECHNOLOGY LABORATORY       SAMPLING PROGRAM (RPATS)

Background

The Clear Air Coalition, comprising California businesses, industries, agriculture and government agencies, is working to bring California air quality into EPA compliance. The Coalition’s
research, covering a wide area of California, concentrates on sampling and modeling air quality in California’s Central Valley. Coalition research projects, funded for nearly $45 million to improve the understanding of air pollution in the region, have improved conditions somewhat: Between 1988 and 1998, the number of days the southern portions of the Central Valley exceeded federal ozone standards fell by 47 percent, and the number of days that particulates exceeded standards fell by 90 percent.

One of the problems confronting the researchers was the collection of air quality data duringadverse weather conditions, such as the Tulle Fog, a low, dense, stagnant and very moist layer of air that blankets the Central Valley during the winter months. Inert gaseous tracer materials sensed by aircraft-mounted instruments have been used for nearly 30 years by Tracer ES&T to study air pollution sources and distribution, but normal aircraft collection of these emissions is impossible at low-altitude and in fog. Deployment of a dense network of moored balloons with adsorption tube samplers attached to tether lines would have been costly and lacked the flexibility to adapt to changing weather conditions. A method of remotely collecting data at low levels during the Tulle
Fog conditions was needed so aircraft pilots would not be at risk in the adverse weather. pilot and eventual incorporation of all permit applications were estimated to be $3.1 million.


Project Description


Tracer ES&T, with assistance and funding from the Department of Energy (DOE) and the Western States Petroleum Associates, analyzed the needs and provided a solution – a remotely-piloted blimp with advance air monitoring instruments capable of sampling and measuring vertical plume measurements in dense fog conditions at elevations less than 1,000 feet and transmitting the data to ground-based computers. The Remotely Piloted Airship for Atmospheric Tracer Sampling (RPATS) combines a commercially available radio-controlled airship, a Global Positioning System (GPS) and real-time data analysis that measures plume concentrations as a function of downwind distance, horizontal location and height above ground.

RPATS is a 30 by 7.5-foot helium-filled blimp capable of lifting a payload of up to 10 pounds. The airship, guided by radio control from the ground, is capable of cruising for over an hour at speeds of 15 to 20 mph or for shorter periods up to 30 mph. The seven-pound payload with its battery-powered gas-sampling equipment is mounted in a gondola on the under side. The system is highly portable. The deflated airship is transported by truck and can be inflated and ready to fly in less than one hour by a ground crew of three. The navigation and computer instrumentation for sampling is in a second truck. Tracer ES&T has two certified pilots trained to locate an emissions plume, fly the airship cross-wind through the plume at various altitudes and distances downwind, collect data and transmit it back to the ground. (The California Air Resources Board also maintains six fixed-wing aircraft and monitoring and meteorological instruments at 185 stations throughout the state to provide data to improve air quality.)

The maiden voyage of the airship was made on December 5, 2000 in connection with a planned release from a steam generator at Belridge oil field in the San Joaquin Valley near Bakersfield. Aera Energy injected a tracer into the steam prior to release to allow analysis of where and how the steam plume is distributed in the atmosphere. The oil field selected offers easy access for the airship and ground-based controls, and is representative of the types of locations that can be monitored using the airship sampling technology. The winter sampling phase extended for about a month .


Project Benefits and Impacts

Development of the RPATS Clean Airship is an excellent example of cooperative efforts by private industry and federal and state government agencies to improve air quality. The airship was designed and tested in California's Central Valley to demonstrate
the effectiveness of remotely collecting and sampling air quality data at low altitude in foggy and overcast weather conditions. The design met rigid specifications for global positioning navigation, maximum sampling capabilities, computer relays, and minimum weight instrumentation to be carried in the small platform beneath the 30-foot blimp. Initial sampling flights have successfully provided data on air currents and air quality in the Bakersfield, CA area.

Because of its uniquely designed capabilities, RPATS will enable the acquisition of real-time in-flight data below 2,000 feet in low-visibility weather, critical air quality data otherwise unavailable because of safety considerations. The airship also offers economy of operation compared to the cost of such alternative systems as networks of sensor-bearing anchored balloons or, in certain respects, fixed-wing aircraft, which obviously fly higher, faster and cover broader areas than RPATS.

The California Air Resources Board estimates that standard aircraft surveys, which deliver only minimal onsite processed data, run about four to six hours flight time per day at a cost of $15,000 to $20,000. For full air quality data reduction and reporting from low altitudes in foggy or overcast weather, Tracer ES&T Inc. is confident they can run four to five RPATS flights daily at a cost of about $6,000 to $8,000. For its designed task, RPATS is an efficient, safe and economical aircraft that fills a vital gap in atmospheric data gathering for air quality surveys.

Army’s LEMV Soars Over Historic Airship Site in First Flight
12 AUGUST 2012
Have any of our readers wondered whatever happened to the long-awaited Army's LEMV (Long  Endurance Multi-Intelligence Vehicle) ? Well, first, we have to recall that in the Army, anything that moves is called a "vehicle" ---- even what most other knowledgeable observers would call an airship .
Emerging from the hangars and storage facilities of the Joint Base Fort Dix / McGuire Air Force Base/Lakehurst Naval Air Station was the LEMV , a 300+ foot long  airship built by Northrop-Grumman.  Its design mission is Intelligence, Surveillance, and Reconnaissance (ISR) ; its original design specifies flight without a crew (Remotely Operated Vehicle --- ROV) , but for this sortie it took to the air for an hour-and-a-half  with a crew to perform a launch-and-recovery and test the operation of its flight control system .
At 300+ feet in length, the airship must have been eerily reminiscent of another tragically iconic airship that was attempting to land at the same Lakehurst airrfield 75 years ago. We'll let you do the math and deduce which Lighter-Than-Air craft we're talking about. Like medieval alchemists avoiding a curse by refusing to speak the forbidden word aloud, we will eschew uttering the fateful name.   
This was the successful culmination of a project that cost on the order of $500,000,000 dollars (we believe that the original contract specification was for "up to three airships") and took years to develop.  To the surprise of this writer and quondam Captain, U.S. Air Force, this airship was built for the U.S. Army . It will undergo at least a month of testing and is the first successful result , in an Olympics event of its own, of the critical need for ISR surveillance of future war zones as well as a host of non-military missions.

eMail HYBRIDPELTA@HOTMAIL.COM for a free copy of the semi-famous 31 Applications for Airships . The first ten (10) requests get a copy of our (genuine U.S. Postal Service) custom-made postage stamp, lightly cancelled, on the envelope containing your 31 Apps . The stamp image is of Roald Amundsen's airship Norge crossing the Arctic ice. 
This is important news, and good news after a series of attempts, because the Pentagon has not previously succeeded in this effort for years, and it's ironic that it was the Army, rather than the Navy (previous Gold Medal winner with its anti-submarine blimps of the Second World War) or the Air Force, whose hegemony of the air is now challenged, possibly as the result of LTA craft being scorned for so long by the USAF as the result of Fighter-Pilot Syndrome --- "If it's not supersonic, we're not interested" .
The LEMV airship is scheduled to head to a war zone next year, at the earliest.  An Army spokesman issued the following statement, "Additional first flight objectives include airworthiness testing and demonstration, and system level performance verification . All objectives were met during the first flight” .
If the LEMV successfully concludes its tests, it may deploy to Afghanistan for combat trials in early 2013, ironically just as the rest of our military forces appear to be returning from that theater of operations .  Its mission there will undoubtedly include persistent surveillance --- as much as weeks on end --- monitoring insurgent troop operations. We understand, to our delight, that it may wind up pulling double duty as a cargo carrier ; it is specified to lift seven tons of cargo and carry it for 2,400 miles at 30 miles per hour . thereby justifying its role in civilian life after its Honorable Discharge. Clearly, there are many jobs in that career choice waiting for it .
Seven tons of cargo ? Will someone please page Dr. Prentice, of ISO Polar and the University of Manitoba, famous for the "Airships to the Arctic" Cnference series ? He has been championing this development of sensible airship transportation along those lines for years. As the unprecedented warming of the entire continent is melting the ice roads upon which depend supply chain logistics TO the north and critical carriage of strategic minerals FROM the north, a suitable replacement is sorely needed.

We steadfastly refuse to call it a blimp. Its design appears to us to be a hybrid, ADDING  lift derived from its aerodynamic shape in which the shape of the entire envelope of the craft acts as an airfoil TO lift derived from the natural lifting power of its lighter-than-air internal gases .
Its ingenious combination of  remote controls, satellite-based information,  and high-technology sensors, appears to be a fairly effective, but complex, mix.
 The airship’s inaugural sortie had been pushed back several times;  combining a giant airship with satellite-based remote controls and the latest high-tech sensors is more difficult than Northrop thought it would be.  As happens with any new integration of complex technologies, the Army had to  extend its initial schedule of test and approval several times. The first flight was scheduled for June, but in both military and major civilian projects a two month delay is not unreasonable. Northrup
Lockheed Martin, a Northrop-Grumman competitor, was working to receive a multi-billion-dollar contract to develop a cargo airship, dubbed the Walrus. At the last minute, the Pentagon zeroed out funding.
Lockheed Martin, never one to give up easily, continued to develop its Walrus airship designs using its own financial resources and finally sold its first modern LTA airship design to a Canadian cargo company for an unspecified sum.
We have no details of that transaction, and we understand that the Army does not engage in entrepreneurial enterprises, BUT we believe that it would have been a good plan to heed the dictum condensed from a paragraph in an Airships to the Arctic Conference  : "Don't sell 'em, lease 'em?" .
We wish both Northrop-Grumman AND Lockheed Martin notable success on these landmark projects. Our country can't lose !
