Mitsubishi Heavy Industries and Boeing Complete MB-XX Cryogenic Upper Stage Rocket Engine Thrust Chamber Assembly Test Program
TOKYO, Japan and ST.LOUIS, Mo., August 12, 2002 – Mitsubishi
Heavy Industries, Ltd (MHI) and the Rocketdyne Propulsion & Power
unit of The Boeing Company (NYSE: BA) have successfully completed
the preliminary MB-XX full-scale Combustion Chamber / Injector Assembly
Flight-like hardware was tested at the MHI Tashiro Test Facility
in Japan at full operating pressure and temperatures in multiple test
series conducted over a two-year period. Key performance parameters,
heat loads, combustion stability and hardware durability was verified.
“Validation of MB-XX combustion chamber and injector design
is a major development milestone and helps solidly position our team
as a leading supplier for the next-generation upper stage engine,”
said Byron Wood, vice president and general manager for Boeing Rocketdyne.
“The MB-XX program is a major business initiative for Boeing
and MHI and represents a significant commitment by both companies
to the future of rocket propulsion.”
“The successful Boeing-MHI MB-XX cryogenic upper stage engine
team is a good example of an excellent Boeing-MHI working relationship,”
said Junichi Maezawa, general manager for MHI Aerospace Headquarters.
“Completion of MB-XX thrust chamber assembly testing represents
significant progress in the development of the MB-XX engine”.
The team of MHI and Boeing Rocketdyne has been commercially developing
the MB-XX since 1999 in response to future upper stage engine requirements.
The MB-XX will provide improved reliability, operating margins and
performance over existing upper stage engines. The MB-XX design features
proven and reliable technology drawn from Boeing Rocketdyne’s
and MHI’s combined decades of propulsion development and innovation,
including industry leadership in the use of leading-edge engineering
