February 2002 Space Launch Initiative Media Update: Stennis Space Center completes testing of Boeing Rocketdyne advanced catalyst bed for SLI

Stennis Space Center completed the final phase of the Boeing Rocketdyne
advanced catalyst bed development program Jan. 16. Hydrogen peroxide is
being pursued as a storable upper-stage rocket propellant because it is a
less toxic alternative to currently used propellants. Approximately 14,000
pounds of hydrogen peroxide propellant was handled safely and expended in
support of this phase of testing.

The test program primarily featured 98 percent concentration hydrogen
peroxide, with additional tests performed at 72 percent at the request of
the U.S. Air Force. Testing for the project began Nov. 1, last year.

The material used in the catalyst bed reacts with hydrogen peroxide to
produce super heated steam and oxygen. The gas from the catalyst bed can be
used to drive a gas turbine, provide thrust as a monopropellant or provide
an oxidizer for bi-propellant engines.

A total of 269 tests in 29 days, with an accumulated duration of 29,650
seconds on five test articles, were successfully accomplished in this phase
of testing, including one catalyst bed that was tested to 10,285 seconds
with 98 percent hydrogen peroxide. This demonstrated double Rocketdyne’s
catalyst life goal for 98 percent hydrogen peroxide.

Data indicated overall performance was excellent. This testing will pave the
way for follow on testing of advanced turbopumps and hypergolic injectors
being developed for upper stage engines under NASA’s Space Launch
Initiative.

ATK Thiokol’s SEHO to manufacture Space Launch Initiative composite tank
dome

ATK Thiokol’s Science and Engineering Huntsville Operations (SEHO) is
manufacturing a subscale composite tank dome for NASA’s Space Launch
Initiative (SLI) for a second-generation reusable launch vehicle. The
subscale composite dome will be manufactured for Northrop Grumman under
contract to NASA at the Marshall Space Flight Center’s National Center for
Advanced Manufacturing. The contract will aid Northrop Grumman in
demonstrating that the composite lay-up requirements for the program can be
met at a subscale level. Northrop Grumman was one of the contractors funded
under NASA’s first phase of the SLI development program. Successful
fabrication of the dome will lead to completion of an entire subscale tank
by this spring.
