Rolls-Royce to add Parker Aerospace heat management valves to the Trent XWB engine programme

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 programme

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 and variable frequency generator surface air cooled oil cooler thermal bypass valve. The oil bypass valve is required to maintain the engine lubrication oil and fuel temperatures within defined limit,s contributing to optimum engine performance. The thermal bypass valve is installed in each variable frequency generator oil circuit on the engine to avoid overcooling the oil.
 

The Rolls-Royce Trent XWB is the sole engine currently available to power the new Airbus A350 XWB family of aircraft. Parker Hannifin estimates that the pneumatics package will generate approximately $175 million in revenues over the life of the programme.
