Triumph Actuation Systems selected CIRCOR Aerospace and its Aerodyne Controls brand to supply the Landing Gear Emergency Blow-Down System for the Sikorsky CH-53K Helicopter. CIRCOR Aerospace will design, develop, and manufacture the landing gear blow-down system from the Ronkonkoma, NY, facility. In the event of hydraulic power loss, the emergency blow-down system provides pneumatic power to the Triumph actuators that extend the landing gear. Aerodyne will provide an integrated unit that includes all necessary valves, gauge, and nitrogen storage bottle in a small manifold mounted on the actuator.
