Boeing Rocketdyne RS-68 Engine Triumphs in 10k Run

Apr 23, 2001, 01:00 ET from Boeing Rocketdyne

    CANOGA PARK, Calif., April 23 /PRNewswire Interactive News Release/ -- The
 Rocketdyne RS-68 engine, being developed by The Boeing Company for the Delta
 IV family of launch vehicles, has achieved a major milestone in logging more
 than 10,000 seconds of accumulated hot-fire test time.  The engine program is
 on track for first launch of the Delta IV in early 2002.
     To date, the RS-68 program has actually accumulated 11,639 seconds of test
 time across the program.  Currently, two engines are being tested-one at the
 Air Force Research Laboratory (AFRL) at Edwards AFB, Calif., and one at NASA's
 John C. Stennis Space Flight Center, Miss.  In addition, a third engine is
 being fired as part of the Delta IV Common Booster Core testing at Stennis.
 An indication of the aggressiveness of this program is the fact that recently
 the two test teams were able to complete three back-to-back-to-back hot-fire
 tests in less than 48 hours.
     "We've moved to a higher plateau regarding the frequency of our engine
 tests," said Rocketdyne Vice President and General Manager Byron Wood.  "The
 Boeing employees at Stennis, AFRL and Canoga Park have done a tremendous job
 of massaging the test and evaluation process to get us to this point."
     The rapid pace of testing can be credited to continuous improvements by
 the development and test team, according to RS-68 Program Manager Rick Baily.
     "The hardware is operating as predicted and we now have a streamlined flow
 for testing, evaluating results and preparing for the next test," said Baily.
 "This puts us on track for wrapping up testing by fall as we transition from
 development to production."
     In addition to the accumulated hot-fire time, other significant milestones
 are being met.  To date, 35 of 42 demonstration test objectives have been
 achieved.  Engine 10108, being tested at Stennis has achieved the 2,450-sec.
 Endurance Limit with the modified Fuel Turbopump; this indicates satisfactory
 operation with life extension modifications to the turbo-pump.  All recent
 tests have been at target conditions and the program has run extended duration
 tests to 20 percent greater than a mission requirement.
     The RS-68 engine is a liquid hydrogen - liquid oxygen booster engine that
 generates 650,000 lbs. of thrust.  It is the first large, liquid-fueled rocket
 engine developed in the United States since Rocketdyne developed the Space
 Shuttle Main Engine.
