Rolls-Royce has selected a proprietary composite technology produced by Goodrich Corporation for use in the Demonstration phase of the F135 propulsion system's LiftFan for the Joint Strike Fighter (JSF).
Goodrich will provide LiftFan clutch friction material for the Short Take Off Vertical Landing (STOVL) version 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 tailored to provide the right amount of friction while absorbing that heat.
According to Paul Walsh, Vice President, High Temperature Composites for Goodrich, ""Our F135 propulsion system design team has been working in close partnership with Rolls-Royce since the early days of the program to develop a friction material that would survive the extreme application and at the same time meet Rolls-Royce's cost requirements. As part of Goodrich's Aircraft Wheels and Brakes division, we have over 50 years of experience in developing friction materials for demanding aerospace applications. We're proud to be part of the overall Goodrich team participating on this exciting program.""
The company estimates the overall potential value of its JSF business to be $4-5 billion in revenue over the life of the program, including original equipment and aftermarket sales and service. Goodrich has been selected to provide the following to the F-35 -- landing systems, fuel quantity gauging components and the associated wiring harnesses as part of the F-35's fuel measurement system, the LiftFan driveshaft and coupling, the anti-icing system, and the rotary-geared actuators for the weapons bay door drive system.
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.
Solvay has signed a ten-year agreement for the supply of composites and adhesives to be used across Bell's military and commercial rotorcraft programmes, including the Bell 429, 407, 505, 525, V-22, and UH-1.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
With the aim developing a broader platform for additive manufacturing (AM) technologies, the University of Exeter, UK, and Victrex, have formed a strategic partnership to introduce next-generation polyaryletherketone (PAEK) polymers and composites while improving the performance of the underlying AM processes.
