Aircraft Super Integrated Power Unit 821461

An SIPU is a single aircraft power unit capable of providing (1) electrical, pneumatic, and hydraulic power for ground maintenance and standby operations, (2) normal main engine start power, (3) emergency in-flight electrical and hydraulic power, and (4) in-flight emergency main engine restart power. Power can be obtained from: jet fuel combustion with air for the ground operations and normal engine starts; a gas generator system using on-board stored propellants for the emergency power and emergency engine restart functions; and the aircraft main engine compressor air as a second source for the emergency electrical and hydraulic power function.An SIPU concept demonstration program is currently near completion at Rockwell International's Rocketdyne Division, sponsored by the Aeropropulsion Laboratory at Wright-Patterson Air Force Base. The program is for design, fabrication, assembly, and test of a demonstrator SIPU capable of performing all four functions.
