PARIS - PARIS AIR SHOW - Hamilton Sundstrand Corporation, a subsidiary of United Technologies Corp. (NYSE: UTX), is supporting Airbus in its A350 XWB systems integration testing on the aircraft and its Rolls-Royce engine.

"Hamilton Sundstrand is proud of our company's long and successful partnership with Airbus, allowing us to play a significant role in the A350 XWB's development," said Hamilton Sundstrand President Alain Bellemare.

Hamilton Sundstrand's Electric Systems business was selected by Airbus to provide the A350 XWB's Ram Air Turbine and Electric Power Generation System (EPGS) - comprising four 100 kVA, 230-volt variable frequency generators and four generator control units. The EPGS is undergoing successful testing not only at Hamilton Sundstrand's Rockford, Ill., facility but also at Airbus and Airbus' partners including Rolls Royce.

Hamilton Sundstrand's Ratier-Figeac unit, based in Figeac, France, will supply one pilot, and one co-pilot cockpit side stick controller per aircraft. The new side stick controller will make its first flight later this year on an Airbus A340 before entering into service on existing Long Range aircraft family in 2012. Ratier-Figeac was also selected by Diehl to provide the cockpit flap control lever. The first units have been tested at Ratier-Figeac and delivered to Airbus.

Hamilton Sundstrand's Kidde Aerospace & Defense subsidiary was selected by Honeywell to provide the aircraft's bleed air overheat detection system. Through Honeywell, Hamilton Sundstrand's Nord-Micro business will provide the aircraft's ventilation control system including fans and humidification/dehumidification.

Additionally, Hamilton Sundstrand's Engine & Control Systems business has tested and delivered to Rolls-Royce the first pneumatic engine start systems used for the initial engine runs.
