The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada.Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since.
Congress only approved the purchase when it was assured that a U.S. source would be found for the PT6T engines. This source was Pratt & Whitney Engine Services in Bridgeport, West Virginia, which was established in 1971 to assemble and test new T400-WV-402 engines. As a result, the U.S. military ordered 294 Bell 212s under the designation UH-1N ...
Combining the engine and wings of the PAC Cresco with a new larger fuselage and modified tail, all versions to date have been powered by a 750 hp (560 kW) Pratt & Whitney Canada PT6 turboprop. It is designed and manufactured in Hamilton, New Zealand , by Pacific Aerospace Limited .
The availability of the 550 shaft horsepower (410 kW) Pratt & Whitney Canada PT6A-20 turboprop in the early 1960s made the concept of a twin feasible. A DHC-3 Otter with its piston engine replaced with two PT6A-4 [3] engines had already flown in 1963. It had been extensively modified for STOL research. [4]
The Model 3000/T-6 is a low-wing cantilever monoplane with enclosed tandem seating for two. It is powered by a single Pratt & Whitney Canada PT6A-68 turboprop engine in tractor configuration with an aluminum, 97-inch (8.1 ft; 2.5 m), four-blade, constant-speed, variable pitch, non-reversing, feathering propeller assembly and has retractable tricycle landing gear.
The engine maintenance interval (time-on-wing) is increased from 14,000 hours to 20,000 hours and would use three percent less fuel than the PW127M. [6] The engine series will premiere as the standard powerplant on all new ATR 42 and ATR 72 aircraft, with a launch order from Air Corsica using the PW127XT-M engine model. The PW127XT-N variant ...
Re-engined with PT6A-67As and five-blade composite propellers instead of the PT6A-60A engines with unit power increasing from 1,050 to 1,200 hp (780 to 890 kW), boosting the maximum cruise speed by 50 kn (93 km/h) to 340 kn (630 km/h) and capable of climbing to 35,000ft in 19min; Blackhawk targets 30% of the 850 King Air 300 globally.

Two further turboprop prototypes followed in 1989 and 1990, powered by a Czech-built 560 kW (750 shp) Walter M-601E and a PT6A-25 as the PZL-130TB and PZL-130TP respectively. [ 5 ] In 1990, development of the piston-engined Orlik was abandoned, as the Polish built radial engines gave insufficient power, with Polish interest switching to the M ...
