ATK successfully tests rocket nozzle for Boeing RS-68 engine.
ATK (Alliant Techsystems), Minneapolis, Minn., reported that a rocket
nozzle for the Boeing RS-68 engine developed by Thiokol Propulsion Corp.,
Brigham City, Utah, has successfully completed a series of static tests
conducted by Boeing at the NASA Stennis Space Center, Miss., and the Air
Force Research Laboratory, Edwards Air Force Base, Calif. The tests
culminated with a 303-second firing at mixed power levels and a 300-second
test at full power for 20 percent longer than is required during flight. The
engine was designed by Boeing Rocketdyne Propulsion and Power and will
provide first-stage propulsion for the Boeing Delta IV launch vehicle,
scheduled for its maiden voyage in 2002.
