The Lycoming (now Honeywell) LTS101 is a turboshaft engine family ranging from 650 to 850 shaft horsepower, used in a number of popular helicopters, and, as the LTP101 turboprop, light aircraft. Both models carry the US military designation T702. The engine was originally designed at the Lycoming Turbine Engine Division in Stratford, Connecticut, but is now produced by Honeywell Aerospace.
