Ram Air Turbine

The Ram Air Turbine (RAT) is at the heart of an aircraft’s emergency power system. In extremely rare instances when airplanes lose power, the ram air turbine deploys from the airplane's wing or fuselage and rotates to extract sufficient power from the airstream to control and land the aircraft. The business designs and manufactures hydraulic, electric and hybrid RATs. 

Technology enhancements include use of a self-governing device that limits turbine speed and minimizes the size of the RAT.

Key customer benefits include greatly enhanced safety of flight. In fact, the company’s RAT systems are responsible for saving approximately 1,700 lives in 16 documented events.​
