How does the 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.
Do turboprops have reverse thrust?
Propeller-driven aircraft generate reverse thrust by changing the angle of their controllable-pitch propellers so that the propellers direct their thrust forward. Piston-engine aircraft tend not to have reverse thrust, however turboprop aircraft generally do.
How many PT6 engines have been made?
Since the PT6A family entered service in the 1960s, more than 41,000 engines have been produced. To date, the PT6A has accumulated 335 million flying hours and is therefore a highly proven and durable engine.
How much is a pt6 overhaul?
PT6A Series Overhaul The PT6A is the most popular turboprop engine in history. It’s well known for its extremely high reliability. Overhaul costs range from $160,000 to $600,000.
How much does a pt6 engine weigh?

How does a PT-6 turboprop engine work?
A PT-6 turboprop engine. f Gear Coupled / Fixed Turbine And Free Turbine There are two types of multiple stage turbine configurations in turboprop engines: gear coupled also known as fixed turbine, and free turbine. In a fixed turbine engine, all turbine stages are connected to a single shaft.
What’s the difference between PT6 and pt6e 67xp engines?
The new turbine design of the PT6E-67XP engine model powering the PC-12 NGX aircraft allows for quicker climb, greater speed (based on greater thermal energy), and a 10 per cent increase in power (at sea level) when compared to the PT6A-67P engine model deployed in the current PC-12 NG airframe.
How does the Pratt and Whitney PT6 E series EEC work?
It changes how the pilot sees information, how the maintainer accesses information on the engine, and even how it interacts with our training manuals.” The PT6 E-Series EEC allows a pilot to start and stop the engine with the push of a button, while being protected against hot and hung starts.
