NASA has selected a team led by Ball Aerospace & Technologies Corporation of Boulder, Colo., for a technology demonstration of a high performance "green" propellant alternative to the highly toxic fuel hydrazine. With this award, NASA opens a new era of innovative and non-toxic green fuels that are less harmful to our environment, have fewer operational hazards, and decrease the complexity and cost of launch processing. Today's use of hydrazine fuel for rockets, satellites and...

Technology used to shape rocket fuel tanks could help one German company to form floats for industrial chemical tanks and oil rigs, thanks to funding from ESA. ESA's Ariane 5 rockets steer with small rocket engines firing bursts of hydrazine, a highly volatile fuel stored under high pressure in corrosion-resistant tanks. The best metal for the tanks is Titanium 6/4 because it is a strong and light alloy of titanium, aluminum and vanadium that doesn't react with the hydrazine inside....

Trinitramid "“ that's the name of the new molecule that may be a component in future rocket fuel. This fuel could be 20-30 percent more efficient in comparison with the best rocket fuels we have today. The discovery was made at the Royal Institute of Technology (KTH) in Sweden. "A rule of thumb is that for every ten-percent increase in efficiency for rocket fuel, the payload of the rocket can double. What's more, the molecule consists only of nitrogen and oxygen, which would make the...

On the day running up to launch when a spacecraft is fuelled, ground personnel look more like astronauts than engineers, putting on spacesuit-like protective gear. This is an essential precaution when dealing with the current hydrazine fuel, but a new development could make satellite fuelling no more dangerous than filling up a car. First used in rocket engines by the German Luftwaffe during World War Two, hydrazine remains the main propellant of choice for a satellite's onboard...

U.S. scientists say they are developing an improved type of gelled rocket fuel that is the consistency of orange marmalade. Purdue University Professor Stephen Heister, who is leading one of two teams on the project, said gels are inherently safer than liquids because they don't leak, and they also would allow the military to control rockets better than is possible with solid fuels now used. Motors running on gelled fuels could be throttled up and down and controlled more precisely than...

Engineers and food scientists are teaming up to develop a new type of gelled fuel the consistency of orange marmalade designed to improve the safety, performance and range of rockets for space and military applications. "This is a very multidisciplinary project," said Stephen Heister, the Purdue University professor of aeronautics and astronautics who is leading one of two teams on the project, which is funded by the U.S. Army Research Office. Gels are inherently safer than liquids because...

NASA's John C. Stennis Space Center will provide propulsion system acceptance testing for the Taurus II space launch vehicle, which Orbital Sciences Corporation of Dulles, Va., is developing. The first Taurus II mission will be flown in support of NASA's Commercial Orbital Transportation Services cargo demonstration to the International Space Station. The demonstration currently is planned for the end of 2010 from NASA's Wallops Flight Facility on Wallops Island, Va. Orbital's Taurus II...

Researchers have synthesized a new class of aluminum-hydrogen compounds with a unique chemistry that could lead to the development of more powerful solid rocket fuel and may also, in time, be useful for hydrogen-powered vehicles or other energy applications. An article about this research, led by scientists at the Johns Hopkins and Virginia Commonwealth universities, is published in the Jan. 19 issue of the journal Science. The team also included scientists at University of Konstanz and...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
