With excellent performance, reliability, and value, the Pratt & Whitney Canada (P&WC) PT6 turboprop aircraft engine entered service in 1964 and continues to evolve, powering mid-size aircraft across the world. Ranging in power from 500 shp to over 2,000 shp and available in over 70 models, it offers flexibility and capability for a variety of applications. It consists of a gas generator with accessory gearbox and a free-power turbine with reduction gearbox. New technologies have enabled the PT6 to gain more power without significantly increasing size or weight, reduce emissions, and enhance ease of operation.

PT6 variants are found in helicopters, boats, and industry. According to the P&WC website, the PT6 turboprop has 400+ million flying hours and flies in 180 countries.

This Pratt & Whitney PT6 is displayed in the Museum's Main Gallery as a tribute to the many aircraft it powers around the world.
