Our door actuation dampers and propeller brakes are flight safety control systems. Collins Aerospace’s systems are highly reliable and commercially proven. We offer flexible and optimized solutions for an array of customer needs.

Door dampers are fitted in the door arm mechanism and ensure soft closing and holding open of the door. Passenger door dampers assist with normal open and close operation, as well as emergency door opening during evacuation.

Propeller brakes replace the auxiliary power unit and stop the propeller, avoiding its rotation on the ground. Helicopter rotor brakes keep the rotor from turning when a rotary-wing aircraft is parked and during engine spin-up. These systems enhance the safety of ground operations.
