Hamilton Sundstrand’s Power Systems business has successfully completed ETOPS (extended-range operations) testing of its APS5000 auxiliary power unit (APU) for the Boeing 787 Dreamliner.
“This is a major accomplishment for our team,” said Danny Di Perna, Hamilton Sundstrand Power Systems vice president and general manager. “We are very proud to have successfully completed the ETOPS test on the APS5000 APU in support of Boeing’s 787 testing phase.”
To date, the APS5000 APU has logged 10,000 operating hours and successfully completed 24,000 starts in its lab- and flight-test program. It provides the 787 electrical power while on the ground and with back-up power while in flight. The APS5000 APU features two 225 kVA, 230 VAC starter/generators, an eductor cooling system, variable speed operation, no-break power transfer capability and a 15,000-hour mean time between overhaul core engine design. The APU starts and operates throughout the airplane flight envelope.
As the largest system supplier on the 787 with nine major systems, Hamilton Sundstrand expects the program to generate $15 billion in revenue over its lifetime. The company supplies the program’s environmental control system (ECS), nitrogen generating system (NGS), auxiliary power system (APS), electrical power generating and start system (EPGSS), remote power distribution system (RPDS), primary power distribution system (PPDS), ram air turbine (RAT), electric motor pump (EMP), fire detection and suppression system and the gearbox system for the Rolls-Royce Trent 1000 engines under development for the 787.
