NASA has begun a set of flight tests of biofuels based on nonfood plants to determine their emissions and performance effects on jet engines. The tests started Feb. 28 using NASA's DC-8 aircraft, which was outfitted as a laboratory and was tracked by a Falcon HU-25 equipped with instrumentation.
The biofuel is based on the camelina plant, a relative of mustard and canola. It's also a relative of oilseed, the basis of the 100 percent nonfood jet fuel used by Canada's National Research Council last fall to power a Falcon 20 civil jet. (See: First Civil Jet Flies on 100 Percent Non-Food Biofuel .) Camelina oil is a commercial crop, and the EPA has just approved its use as a low-carbon feedstock under the Renewable Fuel Standard Program.

NASA's tests, expected to continue for about three weeks, are being conducted under the Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS) project run jointly by NASA's Glenn Research Center in Cleveland, its Langley Research Center in Virginia, and its Dryden Aircraft Operations Facility in Palmdale, Calif. The tests will be conducted primarily at Edwards Air Force Base. The DC-8 will fly at altitudes of up to 40,000 feet, and the Falcon HU-25 will follow it at distances from 300 feet to more than 10 miles.
The tests will compare emissions, performance, and contrails generated by the aircraft using two different fuels: standard JP-8 jet fuel and a blend of equals parts JP-8 and camelina oil-based fuel. The primary aim is to determine the effects of the different fuels on the environment. The DC-8, based at NASA's Dryden facility, has been modified to support the Airborne Science mission. NASA has used the aircraft for research such as testing prototype satellite instruments, verifying data received from satellites, receiving telemetry data from space vehicles while they are launched or during re-entry, and investigating surface and atmosphere conditions on Earth.
The ACCESS program is being conducted under the aegis of NASA's Fixed Wing Project, part of the agency's Aeronautics Research Mission Directorate. Next year, NASA plans to perform more extensive ACCESS flight tests based on data gathered from these flights.
Alternative fuels are not a new field for NASA. The agency studied alternatives with ground-based instruments in 2009 and 2011. Past research has looked at fuels based on algae and chicken fat.
Thanks for covering this, Ann. It's great to see NASA backing the use of biofuels and experimenting with alternative fuel for its gas-guzzling vehicles! Hopefully their research will set a precedent and pave the way for more widespread use of alternative fuels. Any idea why these chose fuels based on these particular plants? It seems like there are quite a number of plant-based biofuels emerging.
You're welcome, Elizabeth. I know the military has done research in this area, as you'/ve covered for DN, but the only NASA work I'd seen before this was the OMEGA algae biofuel project. They seem to be playing it pretty close to the vest regarding what they are or aren't planning to actually use, or why they choose one plant source over the other. But the fact that the EPA just listed this one as a qualifier under the RFS program indicates to me that they may be moving from the wide range of R&D to working on stuff that's got a higher probability of being used.
Ah well, yes, much better to focus on something that might actually become a widely used biofuel in the future. It's good to see NASA focusing like that. Not surprising they are being a bit hush hush about the whole thing. It is NASA, after all. Will definitely look forward to future developments here.
Ann, that's good initiative from NASA, a pioneer in R&D. I think most of such innovations are coming from NASA and various other defence labs. Once after proving the technology, it's finally transferring to public for addressing common issues. Any idea what's are the ingredients of bio fuel?
You're probably right, Mydesign, but hey, whatever works. As long as they are researching ways to replace gasoline and oil-based fuels with more environmentally friendly, fuel-efficient options, it's all the kind of work that needs to be done, and quickly.
Mydesign, this one is based on the camelina plant, as we say in the article. It's another relative of mustard and canola, in the Brassica family of plants, and also related to the oilseed plant the Canadians are using in a 100% biofuel jet fuel. The NASA fuel being tested, however, is a 50-50 blend with regular, petro-based JP-8 jet fuel.
sensor pro, not sure what you mean by wasteful PR. The OMEGA project was not just PR--it was real R&D and had some good results. Although I don't believe it was aimed at jet fuel, whereas this one is. Or did you mean something else?
Whet I ment by wasteful PR is a waste of time that NASA is spending on glorifying the contribution of other nations to space exploration. The waste of time to be politically correct. If we compare new developments coming out from NASA now to lets say 15 years ago, it is not even close. They lost huge number or engineers and scientists during the cuts of 2 and 3 years ago. I still remember that they coul not find the engineering team to fix the oxygen problem on the space station because they were let go three month earlier. !!!!
Im happy to see some movement on the development side from NASA.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
