Our ram air turbine (RAT) is at the heart of an aircraft’s emergency power system. In fact, they are responsible for saving approximately 1,700 lives in 16 documented events.

If an airplane were to lose power, the RAT would deploy from the airplane’s wing or fuselage and rotates to extract sufficient power from the airstream to control and land the aircraft.

RATs are designed to be small and have a self-governing device that limits the turbine’s speed. Collins Aerospace designs and manufactures hydraulic, electric and hybrid RATs.
