777X

UTC Aerospace Systems has secured a contract with Boeing to supply electric power-generating system, cabin air-conditioning, and other components for the 777X aircraft.

Said to be a completely re-designed electrical generator system, the new equipment will provide 25% more power than its counterpart on the 777 aircraft.

Designed for the 777X, the system will feature two 150kVA integrated drive generators, an auxiliary generator, three generator control units and a bus power control unit.

UTC Aerospace Systems aerospace customers and business development vice-president Gail Baker said: "These systems not only comprise proven technologies from our systems experience on the Boeing 777, but will also contain new technical solutions to support the improved performance and operating efficiencies of the 777X."

Under the contract, the company will also provide cabin temperature control equipment, airfoil and cowl ice protection technology and a complete ventilation suite.

The fire / overheat protection system, power door opening (PDOS) actuation, a lighter-weight cargo loading system, cabin attendant seating, brakes, main wheels and nose wheels will also be provided under the contract.

"[These systems] will also contain new technical solutions to support the improved performance and operating efficiencies of the 777X."

UTC’s speciality heating, waste and water management, and air data systems such as angle of attack will be installed on the 777X.

These new components will increase performance, enhance reliability and improve passenger comfort, UTC said.

Boeing previously selected Liebherr-Aerospace, Aircelle, GE Aviation, BAE Systems, and Nabtesco to supply various systems and components for the aircraft.

Liebherr-Aerospace will provide folding wing-tip system components for the 777X, Aircelle will provide titanium exhaust systems for the GE9X turbofan engines, GE Aviation will supply common core avionics and electrical power systems.

BAE Systems and Nabtesco have been selected to supply remote electronic units and flight control actuation systems, respectively.
