WINDSOR LOCKS, Conn. Jan. 25, 2011 China

In addition to the 30 kVA electric Ram Air Turbine, the emergency system includes a generator control unit, auto deploy control unit, actuator, stow panel and generator line contactor. In the unanticipated loss of in-flight power from the engines, the RAT deploys into the airstream and produces power to the cockpit and flight controls, to safely land the aircraft.

COMAC had previously chosen Hamilton Sundstrand’s Kidde Aerospace & Defense business to provide the aircraft’s integrated fire and overheat protection system. Hamilton Sundstrand’s Ratier-Figeac business will supply the aircraft’s pilot controls, which includes side sticks, rudder brake pedals, speed brake control level, control panel and the Thrust Control Quadrant.
