Goodrich has been chosen by Rolls-Royce and BAE Systems to provide LiftFan clutch friction materials and ice detection systems for the F-135 and F-35 versions of the Joint Strike Fighter (JSF) aircraft.
Rolls-Royce has contracted Goodrich to provide clutch friction material for the F-135 Short Take Off Vertical Landing (STOVL) variant of the JSF aircraft. First production deliveries of LiftFan clutch packs for the Joint Strike Fighter are scheduled for 2009.
Goodrich’s Santa Fe Springs, California-based high temperature composites team will provide a clutch pack for each JSF STOVL propulsion system. The clutch pack transmits the torque from the engine to the LiftFan to allow vertical takeoff, and then disengages when wing-borne flight is underway.
The engine initially transfers the equivalent power of three train locomotives through the clutch, and the rapid engagement results in extremely high heat generation. Goodrich’s composite materials are said to be tailored to provide the right amount of friction while absorbing that heat.
Rolls-Royce is developing the LiftFan as part of the Rolls-Royce LiftSystem, part of a System Development and Demonstration subcontract from Pratt & Whitney, for the F135 propulsion system for the Joint Strike Fighter program.
For its part, BAE Systems has contracted Goodrich to provide the ice detection system for the JSF. The system advises pilots when icing conditions are present and will be used on the conventional, carrier and Short Take-Off Vertical Landing (STOVL) versions of the aircraft. Lockheed Martin, BAE Systems and Northrop Grumman are principal industry partners developing the F-35.
Goodrich estimates the overall potential value of its JSF business to be between $4 and $5 billion in revenue over the life of the program, including original equipment and aftermarket sales and service.
