Hamilton Sundstrand's Boeing 787 Auxiliary Power Unit undergoes successful initial start-up

The Hamilton Sundstrand APS 5000 Auxiliary Power Unit (APU) for the Boeing 787 Dreamliner had a successful initial start-up on Boeing's ZA001 development aircraft Tuesday, May 12. The testing took place at Boeing's Everett, Wash., facility. Hamilton Sundstrand is a subsidiary of United Technologies Corp. (NYSE: UTX).

"Hamilton Sundstrand is pleased to partner with the Boeing team to help achieve this success for the 787 Dreamliner," said Tim Morris, Hamilton Sundstrand president, 787 Programs. "Our employees have been committed to this program's success since its inception. We are all extremely proud to see it come to fruition."

APUs provide power to aircraft while they are on the ground, and provide in-flight back-up power. The APS 5000 APU is rated at 1,100 shaft horsepower and is designed to start and operate throughout the full range of the 787 operating envelope up to 43,000 feet. The APS 5000 is Boeing's first more-electric APU. It produces 10 percent fewer emissions and is 50 percent quieter than current Boeing 767 APUs. Hamilton Sundstrand Power Systems, based in San Diego, Calif., has more than 13,000 APUs in commercial and military service. The APS 5000 has accumulated 6,020 hours – including nearly 14,000 starts – in the qualification program and has demonstrated outstanding performance during cold weather and high temperature testing, icing and snow testing, altitude simulation and high vibration endurance testing.

In addition to the APU, Boeing chose Hamilton Sundstrand to provide the 787's environmental control system, electric power generation and start system, remote power distribution system, primary power distribution system and high-voltage DC equipment racks, emergency power system, nitrogen generation system, and electric pump subsystem. Hamilton Sundstrand's Kidde Aerospace & Defense business is supplying Boeing with the complete fire protection systems package for the 787. Rolls-Royce also chose Hamilton Sundstrand to supply the gearbox system for its Trent 1000 engine. The 787 program is expected to generate more than $15 billion in revenue for Hamilton Sundstrand over the life of the program.
