F135 Engine Test(click to view full) On November 17, 2006, Stork Aerospace N.V. of the Netherlands and U.S. firm Pratt & Whitney announced an agreement for the production development of components for the new P&W F135 jet engine, one of the two interchangeable engines that will power the F-35 Joint Strike Fighter. This agreement involves new High Performance Machining (HPM) technology for titanium components, and represents a breakthrough in titanium machining as an advanced and efficient production technology for aircraft jet engines. High Speed Machining (HSM) is a production technology for components by means of the machining of solid aluminum to create the desired final form and dimensions. It creates weight savings, consistent quality and substantial cost savings through the elimination of sub-assembly work. HPM is a further development of HSM that works with harder materials like titanium. This allows for a number of improvements, including: * Demonstrable quality improvements * Cost reductions and * Shorter cycle times for a number of critical F135 subsystems, including the exhaust nozzles. Pratt & Whitney is the lead propulsion system contractor for the Lockheed Martin F-35 Joint Strike Fighter. The F135 (an evolution of the F119 jet engine for the F/A-22 Raptor, but […]
