sentences: The Pratt & Whitney Canada PW800 is a turbofan engine in the 10,000 - thrust class, under development by Pratt & Whitney Canada.
 Intended for the regional jet and business jet market, the gear-less PW800 share a common core with the larger, geared PW1000G.
 The first variants were certificated on February 15, 2015 to power the new Gulfstream G500/G600.
The Pratt & Whitney Canada PW100 aircraft engine family is a series of 2,000 to 5,000 horsepower (1,500 to 3,700 kW) turboprops manufactured by Pratt & Whitney Canada.
 The engine first entered service in 1984.
 It dominates its market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engines.
The Conroy Tri-Turbo-Three was a Douglas DC-3 fitted with three Pratt & Whitney Canada PT6 engines by Conroy Aircraft; the third engine was mounted on the nose of the aircraft.
The Basler BT-67 is a utility aircraft produced by Basler Turbo Conversions of Oshkosh, Wisconsin.
 It is a remanufactured and modified Douglas DC-3; the modifications designed to significantly extend the DC-3's serviceable lifetime.
 The conversion includes fitting the airframe with new Pratt & Whitney Canada PT6A-67R turboprop engines, lengthening the fuselage, strengthening the airframe, upgrading the avionics, and making modifications to the wings' leading edges and wing tips.
The Pratt & Whitney Canada PT6T Twin-Pac is a turboshaft engine designed for helicopters.
 Manufactured by Pratt & Whitney Canada, its first application was in the Bell 212 and UH-1N Twin Huey helicopter family.
 The PT6T Twin-Pac consists of two PT6 power turbines driving a common output reduction gearbox, producing up to 2,000 hp at 6,000 rpm.
 The engine is designated T400 by the U.S. military.
The PAC P-750 XSTOL, (formerly known as the PAC 750XL) is a utility aircraft of conventional all-metal low-wing monoplane design, with fixed tricycle undercarriage.
 Combining the engine and wings of the PAC Cresco with a new large 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 Pratt & Whitney Canada JT15D is a small turbofan engine built by Pratt & Whitney Canada.
 It was introduced in 1971 at 2200 lbf thrust, and has since undergone a series of upgrades to just over 3000 lbf thrust in the latest versions.
 It is the primary powerplant for a wide variety of smaller jet aircraft, notably business jets.
Airtech Canada is a Canadian aerospace engineering firm established at the Peterborough Airport, Ontario in 1977.
 It specializes in modifying aircraft for a variety of roles, particularly aero-medical conversions.
 It has also marketed conversions for popular radial-engined transport aircraft such as the Douglas DC-3, de Havilland Canada DHC-2 Beaver and de Havilland Canada DHC-3 Otter.
The MS-500V is a Ukrainian family of military and civilian turboshaft engines developed by Motor Sich.
 The new engine is intended for helicopters with a takeoff weight up to 6 tonnes.
 Its certification is scheduled for the first quarter of 2011, and it will power the new Kazan Ansat-U training helicopter, currently equipped with the Pratt & Whitney Canada PW207K engine.
The Pratt & Whitney Canada PT6, produced by Pratt & Whitney Canada, is one of the most popular turboprop aircraft engines in history.
