How does PT6 engine work?
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.
What type of engine is the PT6?
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.
How reliable is the PT6 engine?
The PT6 family is known for its reliability with an in-flight shutdown rate of 1 per 333,333 hours up to October 2003, 1 per 127,560 hours in 2005 in Canada, 1 per 333000 hours from 1963 to 2016, 1 per 651,126 hours over 12 months in 2016.
Why is pt6 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.
Why is pt6 reverse flow?
the reverse flow of the tractor layout allows for additional FOD protection vis a vis an intertial separator prior to air entering the first stage of the compressor.
