PW100

The PW100 is a family of turboprop engines produced by Pratt & Whitney Canada. It is widely used in regional airliners and utility aircraft. The PW100 series entered service in the mid-1980s and has since undergone numerous upgrades and variants. These engines are known for their reliability, fuel efficiency, and low noise levels.

The core design of the PW100 features a two-spool gas generator, comprising a low-pressure compressor driven by a power turbine and a high-pressure compressor driven by a separate turbine. This configuration contributes to its performance and efficiency. The engines are typically equipped with a three-stage power turbine and a four-bladed propeller.

Several models exist within the PW100 family, including the PW118, PW120, PW121, PW123, PW124, PW125, PW126, PW127, and PW150. Each model offers different power outputs and specifications tailored to the requirements of various aircraft. These engines power aircraft such as the ATR 42/72, Bombardier Dash 8 (Q100/Q200/Q300), and Embraer EMB 120 Brasilia. The PW100's robust design has made it a popular choice for operators seeking dependable and economical propulsion for short-to-medium haul operations.
