The PT6A is a two-shaft engine with a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the propeller through an epicyclic concentric reduction gearbox.
Is the PT6A jet engine?
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. The PT6A covers the power range between 580 and 1,940 shp (430 and 1,450 kW) while the PT6B/C are turboshaft variants for helicopters.
Why is the PT6 so popular?
There are good reasons why the PT6A design is a success. Far simpler than the large radial engines it was built to replace, the engine has a high power-to-weight ratio, for one thing. Its reverse-flow, free-turbine arrangement is even more significant.Feb 5, 2018
