TheHoneywell TPE331 (military designation:T76) is aturboprop engine. It was designed in the 1950s byGarrett AiResearch, and produced since 1999 by its successorHoneywell Aerospace. The engine's power output ranges from 575 to 1,650shaft horsepower (429 to 1,230 kW).[2][3][4]
Garrett AiResearch designed the TPE331 from scratch in 1959 for the military.[5] "Designed as a 575-horsepower engine it was not a scaled-down version of a larger engine, as competitors were offering."[6]The TPE331 originated in 1961 as a gas turbine (the "331") to power helicopters.[6] It first went into production in 1963.[7] More than 700 had been shipped by the end of 1973.[6] It was designed to be both aturboshaft (TSE331)[8] and a turboprop (TPE331), but the turboshaft version never went into production. The first engine was produced in 1963, installed on theAero Commander in 1964 and put into production on the Aero Commander Turbo Commander in June 1965.[citation needed]
The 715 shp TPE331-6 used in theBeechcraft King Air B100 has a 400 hr fuel nozzle cleaning interval, 1,800 hr hot section inspection interval, and a 5,400 hr.time between overhaul; approval is possible for 3,000 hr HSIs and 6,000 hr overhauls, and engine reserves are cheaper than for the PT6A.[9]
