The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was designed in the 1950s by Garrett AiResearch , and produced since 1999 by successor Honeywell Aerospace . The engine's power output ranges from 575 to 1,650 shaft horsepower (429 to 1,230 kW).
The company's first major product was an oil cooler for military aircraft. Garrett designed and produced oil coolers for the Douglas DB-7. [9] Boeing's B-17 bombers, credited with substantially tipping the air war in America's and Great Britain's favor over Europe and the Pacific, were outfitted with Garrett intercoolers, as was the B-25.

Speer pushed Garrett to take on larger incumbents in the general engine propulsion market, but didn't get approval to "boot-strap" the development of the turboprop 331 engine until 1962. The Garrett TPE331 would be Garrett's (later Honeywell's) first fixed-wing general propulsion turbine. [9]

The development of a turboprop derivative from the Honeywell TPE331 also reduced development time and production costs. [ 6 ] [ 7 ] Its applications include Airbus A220 -100 and -300 series, A300, A330, A340, Boeing 767 and 777, Bombardier CRJ700/900/100, Comac C919 and Irkut MC-21.

Cheyenne 400 with TPE331 rear exhaust. In the late 1970s, Piper avoided developing a clean-sheet light business jet to compete with the Cessna Citation I and upgraded its PT6As from 720 to 1,000 hp (540 to 750 kW) Honeywell TPE331-14s. [3] The PA-42-1000 Cheyenne IV was certified in 1984, 43 were built until 1991 and 37 remain in service in ...
