IRKUT MC-21 FLAP ACTUATOR TEST RIG 

UTC Aerospace  will provide a fully integrated high lift flap and slat system for the aircraft, with Comar providing a test rig for the Flap Actuators allowing for quick and easy testing for production testing (PAT) , mechanical fatigue and testing over temperature.

The test rig allows for a number of actuators with differing drive geometry to be located on the rig , the input drive is simulated for speed and torque via a hydraulic servo motor and the output profiled load is applied via a closed loop servo controlled hydraulic actuator . Comar have supplied the total package simulating aircraft mounting, kinematics, loading and environmental conditions, including the integrated electronic control system.
