Hamilton Sundstrand APS5000 APU achieves major milestones

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. The completed testing is an important step in providing ETOPS capabilities for 787s upon initial entry into service. Hamilton Sundstrand is a subsidiary of United Technologies Corp. (NYSE: UTX).

"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 APU 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 MTBO core engine design. The APU starts and operates throughout the airplane flight envelope.
