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]
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.

The Garrett ATF3 (US military designation F104) is a 3-spool turbofan engine developed at the California division of Garrett AiResearch. Due to mergers it is currently supported by Honeywell Aerospace. The engine's design is unusual; the core flow path is reversed twice.
It was Garrett's first free-turbine turboshaft, avoiding the high reduction gear of a single spool turboprop and allowing an easier starting since the gas generator is disengaged from the power turbine. The HP spool turns at 31,500 rpm while the LP spool turns at 19,444, reduced to 1,700 for the propeller: a 11.4 reduction ratio.
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace .
Garrett Motion Inc., formerly Honeywell Transportation Systems and Honeywell Turbo Technologies, is an American company primarily involved in engineering, development and manufacturing of turbochargers and related forced induction systems for ground vehicles from small passenger cars to large trucks and industrial equipment and construction machinery.
In 1981 the B21FT (a B21F with a turbo) was introduced with a compression ratio of 7.5:1 mated with a Garrett T3 turbocharger and a T camshaft. Additional turbo variants, not offered in the US market, were the B19ET and the B21ET, based on the B19E and B21E respectively. The turbocharger increased power output to 127 hp (95 kW) for the B21FT ...
