Fuel savings 60 gal/hr. Approx. 30%
Higher useful load
Weight Saving 50 Lbs from the standard UH-1H T53-13 installation
Less fuel needed for specific operations
No aux tank needed – more useful load
No bleed air requirements with the electric Oil Cooler Blower installation
15,000 ft. Auto Re-lite certification
As the engine increases in altitude, it’s “thermal power” available drops due to air density, because the PT6 is of a newer design era, its “lapse rate” (power fall-off due to altitude) is better (less) than that of the T53
Available Power (not at its max for the Engine Series)
Although the PT6C-67D Engine is certified to 1680 Thermo Horsepower for the Huey TALON installation, the engine series, which includes the PT6C-67A, is certified to a maximum of 2518 Thermo Horsepower. The additional power which is un-utilized in the PT6C-67D helps to improve the overall altitude performance.
The additional “reserve” power available helps with Altitude Performance of the engine.
Electronic Collective Power Anticipator, electronic replacement for the droop compensator system, very responsive
The advanced factory-new engine is equipped with an Electronic Engine Control (EEC) for precise and fast rotor governing with a hydro-mechanical back-up feature that provides for safe engine control and ease of helicopter operation.
