NASA has selected Boeing for the Composite Cryotank Technologies Demonstration effort.
According to NASA, Boeing will design, manufacture and test two lightweight composite cryogenic propellant tanks. They say the demonstration effort will use advanced composite materials to develop new technologies that could be applied to multiple future NASA missions, including human space exploration beyond low Earth orbit.
NASA say that Boeing will receive approximately $24 million over the project lifecycle from their Space Technology Program for the work which starts this month. The tanks will be manufactured at a Boeing facility in Seattle. Testing is expected to start in late 2013 at NASA's Marshall Space Flight Center in Huntsville, Alaska.
"The goal of this particular technology demonstration effort is to achieve a 30 percent weight savings and a 25 percent cost savings from traditional metallic tanks," said the Director of NASA's Space Technology Program, Michael Gazarik at NASA Headquarters in Washington. "Weight savings alone would allow us to increase our upmass capability, which is important when considering payload size and cost. This state-of-the-art technology has applications for multiple stakeholders in the rocket propulsion community."
NASA explain that by continuing the advancement of technologies required for their missions in deep space exploration, science and space operations, the composite cryotank demonstration effort will advance the areas of materials, manufacturing and structures. The tanks incorporate design features and new manufacturing processes applicable to designs up to 10 meters in diameter. Tanks could be used on future heavy-lift vehicles, in-space propellant depots and other Earth-departure exploration architectures.
"This technology demonstration effort is different in the fact that we're focused on affordability concurrently with performance," said John Vickers, NASA Project Manager for the Composite Cryotank Technologies Demonstration effort at Marshall. "This technology has excellent transition potential for NASA and commercial product lines. Critical technology advances such as out-of autoclave composites are being matured, and when demonstrated in an operational environment will let us go well beyond the state-of-the-art."
