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.
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.

Now with GE’s electronic engine and propeller control available in 2018, pilots will enjoy less work in the cockpit.
Which is better General Electric PT6 or H75?
The H75-100 weighs 94 lb (43 kg) more than the equivalent PT6 but pioneers single lever electronic propeller and engine control in general aviation, for an initial TBO of 4,000 hr which could be increased with experience. It promises 10% better fuel burn, 10% longer overhaul and lower maintenance costs than the PT6A-135 for the Nextant G90XT.
When did the General Electric H80 come out?
The H80 was launched in 2009 based on the M601. GE added a new compressor, blisks, blades and new stators to enhance power by 3% and boost efficiency by 10%. It reaches 597 kW (801 hp) ( shaft horsepower) from the M601-F’s 580 kW (780 hp), and improves hot and high performance.
Which is lighter a GE thrush or a GE H80?
The H80 weighs 382 pounds and is lighter than a PT6A-34AG, so the Thrush 510G had its Pinocchio-like nose extended another 14 inches to accommodate the new engine. The change also allowed Thrush to remove ballast from the Pratt & Whitney-powered aircraft, so a GE Thrush is more than 200 pounds lighter.
