A team of engineers from Northrop Grumman Corporation and NASA's
Marshall Space Flight Center, Huntsville (AL) have demonstrated
that a new, specially designed fuel tank made from composite
materials can safely hold and contain liquid hydrogen under
simulated launch conditions.
The tests were conducted Nov. 22 at the Marshall Center, as part of
NASA's Next Generation Launch Technology (NGLT) program, an ongoing
effort to develop and mature technologies required for a next
generation reusable launch vehicle. Liquid hydrogen is an essential
but highly volatile fuel used in the combustion process that
propels rockets. It must be stored and used at -423 degrees
Fahrenheit, a temperature that causes most materials to become
quite brittle.
