    Introduction to the PW500 series

    PW545 Engine

    The high performance PW500 series includes several models, each with different thrust ratings and characteristics to suit different types of aircraft. Some of the key features of these engines include:

    • High bypass ratio, which helps to reduce noise and fuel consumption
    • Compact design, which allows for easy installation and maintenance
    • Low emissions, including NOx emissions that are well below current and proposed regulatory limits
    • Advanced engine health monitoring

    Engine specs and capabilities

    According to PWC, the pw500 is a two-spool engine with a three-stage high-pressure compressor driven by a single-stage, cooled high-pressure turbine and a two-stage low-pressure turbine driving a robust, efficient turbofan. The PW535 and PW545 series incorporate an added compressor boost stage driven by the fan.

    With a thrust rating of 4,118 pounds, the PW545C is the latest and most powerful model in the PW500 series. This engine provides enhanced performance and fuel economy over earlier models and is intended for midsize commercial jets and regional aircraft. The PW500 series is also known for other popular models (statistics provided by Pratt & Whitney Canada Aircraft database):
