(Cleveland, March 9, 2010) -- Parker Hannifin Corporation (NYSE: PH), the global leader in motion and control technologies, today announced that Rolls-Royce has exercised its option to add Parker Aerospace's heat management valves to the pneumatics package it already supplies on the Trent XWB engine program.
Parker estimates that the package will generate approximately $175 million in revenues over the life of the program.
Product design, manufacture, and support will be completed by the Parker Aerospace Fluid Systems Division in Irvine, California. The heat management valve package will include a surface air oil heat exchanger oil bypass valve (SAOHE OBV) and variable frequency generator surface air cooled oil cooler thermal bypass valve (VFG SACOC TBV). The OBV is required to maintain the engine lubrication oil and fuel temperatures within defined limits contributing to optimum engine performance. The TBV is installed in each variable frequency generator oil circuit on the engine to avoid overcooling the oil.
Trent XWB engine. The Rolls-Royce Trent XWB is the sole engine currently available to power the new Airbus A350 XWB family of aircraft.
In addition to the heat management valves, Parker's bill of material on the Trent XWB covers several product lines in support of Rolls-Royce requirements: the pneumatics valve suite that enables anti-icing, turbine case cooling and engine bleed functions; the oil pump that feeds oil to bearings and gearboxes and scavenges that return oil; and the hydraulic engine build-up (EBU) system that includes tubes, hoses, and attaching hardware required to convey the aircraft hydraulic power between the engine-mounted pumps and the aircraft.
