Diagram comparing turbofan and turboprop air-breathing engines. The turbofan shows air split between the compressor and bypassing the engine, while the turboprop shows hot gases driving a turbine that powers both the compressor and a propeller. Key components such as air intake, compressor, combustion chamber, turbine, and exhaust are labeled, with arrows indicating airflow and hot gas movement. turboprop engine driving a single rotation propeller

•History

turboprop, hybrid engine that provides jet thrust and also drives a propeller. It is basically similar to a turbojet except that an added turbine, rearward of the combustion chamber, works through a shaft and speed-reducing gears to turn a propeller at the front of the engine.

The first experimental turboprop aircraft, a modified Gloster Meteor fighter equipped with two Rolls-Royce Trent units, flew in 1945 in England. The first turboprop commercial airliner to enter scheduled service was the Vickers Type 701 Viscount, April 18, 1953.

As a consequence of improvements in turbojet design, the turboprop—less efficient at high speeds—lost much of its importance in the 1960s, although it was retained for relatively short range aircraft.
