Plain English Meaning

A jet-style engine that uses its spinning power to turn a propeller instead of producing thrust mainly from exhaust. The propeller does most of the work of pulling the airplane through the air.

Full Definition

A turboprop engine is a turbine engine that drives a propeller through a reduction gearbox. The engine's hot exhaust gases spin a turbine, which turns a shaft that, after gearing down to a usable propeller speed, rotates the propeller. Most of the engine's useful thrust comes from the propeller; only a small portion comes from the residual jet exhaust.
