  • Composite cryogenic tank under development

    News | 18 Apr 2005 23:00

    <p>Mojave, California-based reusable rocket-powered vehicle developer XCor Aerospace is to build a demonstration composite cryogenic tank under a four-year $7 million NASA exploration systems research and technology contract. </p> <p>The advantage of composite materials is that their thermal stability allows a tank to be part of the vehicle's structure, which saves weight. Normally fuel tanks have to be separate and suspended within the vehicle's structure. The Xcor Aerospace tank would hold liquid oxygen and is to be constructed with a type of fibre and fluoro polymer that the company is currently patenting. </p> <p>The company claims that its technology has the ability to retain its strength and flexibility at cryogenic temperatures and that its fluoro polymer is not flammable. Brittleness and flammability are said by XCor have been issues with previous composite tanks' materials. </p> <p>"We are taking a different approach. Everyone thinks of the X-33 tank, but that tank failed fhttp://www.flightglobal.com/news/articles/Composite-cryogenic-tank-under-development-196724/
  • Leak-proof composite tank could hold fuel or astronauts

    <p>Northrop Grumman technology poised for role in future space exploration programmes</p> <p>Leak-proof composite cryogenic fuel-tank technology developed by Northrop Grumman for NASA's now-defunct programme to develop a second-generation reusable launch vehicle (RLV) could find application under the US space exploration initiative.</p> <p>Efforts to develop a lightweight composite tank that does not permit liquid hydrogen to leak could lead to its use for storing fuels in space while the elements of a manned mission to the Moon or Mars are assembled in orbit. Alternatively, the insulated and leak-proof tanks could be converted into habitats in orbit, says project leader Tod Palm.</p> <p>A prototype tank developed over three years under NASA contracts totalling $30 million last month completed a 40-cycle series of tests leak-free, says Palm, withstanding mechanical and thermal stresses associated with repeated fuelling and simulated launches.

    <p>GRAHAM WARWICK / WASHINGTON DC</p> <p>Routine access to space has proved elusive. As the cost becomes clear questions are being asked about the need to make spacecraft truly reusable.</p> <p>Spaceflight is substantially younger than flight itself - half a century younger - but its pioneers were dreaming of voyaging to the moon and beyond even as the Wright brothers made their first flights 100 years ago. There has been significant progress in the 46 years since the Soviet Union put the first artificial satellite into orbit around the Earth, but the dreams of spaceflight pioneers such as Robert Goddard and Wernher von Braun remain unfulfilled.</p> <p>The truth is that spaceflight is hard, arguably the hardest thing man has tried to accomplish. And if spaceflight is difficult, then safe, routine, commercially viable manned spaceflight is almost impossible - at least for another few decades. The disintegration of the Space Shuttle <I>Columbia</I> during re-entry was a setback for mahttp://www.flightglobal.com/news/articles/Reusable-reality-168568/
  • Cutting to the bone

    <p>GRAHAM WARWICK / WASHINGTON DC</p> NASA is restructuring its aerospace research in the face of budget pressures and demands from US industry for more support for aeronautics <p>US aerospace research and development is at a crossroads. The industry's engine of innovation, NASA, is stalled by budget overruns on the International Space Station (ISS) and beset by criticism of its investment priorities. The agency has launched a fundamental revamp of its research agenda, but could be pre-empted by Congress' increasing concern that the USA is losing its technology edge. </p> <p>NASA, facing cost overruns on the Space Station of between $4.8 billion and $5.4 billion, has been instructed by the new Bush Administration to make the cuts necessary to stay within the $25 billion programme cap (see P30). While the ISS itself is taking the deepest cuts, the consequences are being felt across the agency. </p> <p>The problems are evident in the confusion surrounding NASA's experimental vehiclehttp://www.flightglobal.com/news/articles/Cutting-to-the-bone-134122/
