PW500

The PW500 is an advanced high by-pass ratio turbofan engine, in the 3000-4500 lb thrust range, specifically designed for quiet operation, state-of-the-art fuel efficiency and high productivity benefits to the corporate jet operator.

A common core concept was chosen to cover the thrust range in anticipation of various aircraft requirements. Improved component technology will lead to new standards of durability and reliability.

Main engine components include: Integrally Bladed Rotor (IBR) fan driven by a turbine assembly; common core IBR compressor stages with a single centrifugal compressor driven by a single stage turbine (cooled vane); a reverse flow combustor; and thrust management governed by an advanced hydromechanical fuel control unit. An Electronic Engine Control (EEC) system is available as optional equipment.

Operation
The air enters the engine through the fan. approximately 75% is directed to the annular bypass duct providing most of the engine thrust. The rest is compressed and fed to the combustion chamber where it is mixed with fuel and ignited. The hot gas then expands through the turbine stages. The first stage drives the compressor and the accessories, the second, mechanically independent from the first, drives the fan. Finally, the hot gas is discharged through the exhaust mixer.
