turboprop

n. type of jet engine which includes a turbine-driven propeller adding to the thrust of the jet; aircraft powered by one or more turboprop engines (Aeronautics)

A turboprop engine is a type of gas turbine engine used in aircraft. Most of a turboprop engine's power is used to drive a propeller, and the propellers used are very similar to the propellers used in piston or reciprocating engine-driven aircraft (with the exception that turboprops usually use a constant velocity propeller).
