The Lycoming T53, (company designation LTC-1) is a turboshaft engine used on helicopters and fixed-wing aircraft (in turboprop form) since the 1950s. It was designed at the Lycoming Turbine Engine Division in Stratford, Connecticut by a team headed by Anselm Franz, who was the chief designer of the famed Junkers Jumo 004 during World War II. A much larger engine, similar in overall design, became the Lycoming T55. Both engines are now produced by Honeywell Aerospace.
