In fact, turboprop (and turboshaft which is the same thing, but for applications other than fixed-wing aircraft propulsion) is jet engine designed such that it produces mainly mechanical power instead of thrust. Most commercial airliners use turbofans which are similar in that majority of their thrust does not come from the engine's jet exhaust.
