PT6A Engine Overview
Unmatched versatility, dependability and performance have made the PT6A
engine the most thoroughly proven and popular turboprop engine family
in the 500- to 1,700-shp class, covering a diverse range of applications
across all aircraft markets. We continually invest in technology to make our
engines the most environmentally friendly and to offer even greater value in
the form of higher performance and digital engine control.
The PT6 engine, a lightweight free turbine engine incorporating a reverse
flow combustion path, is designed for aircraft propulsion use. It utilizes two
counter-rotating turbines; one driving the compressor and the other driving
the propeller through a reduction gearbox. The latter turbine is “free”
or independent of the compressor turbine. More recent, higher powered
models incorporate a two-stage power turbine.
Over the years, the PT6 engine has evolved and adapted to a multitude of
uses. The PT6A engine is the turboprop designation, powering commuter,
corporate and utility aircraft, aerobatic trainers, agricultural aircraft, short
takeoff and landing (STOL) aircraft and water bombers. This handbook is
dedicated to the PT6A variant.
The PT6B, C & T (Twin-Pac®) engines are turboshaft variants, providing
reliable power to many of the worlds helicopters and more recently to
tiltrotors.
The ST6 engine is an industrial variant of the PT6 engine, originally
developed for the United Aircraft Corporation (UAC) TurboTrain and
intended for stationary application.
