The Campini Caproni CC.2 Motorjet powered aircraft.

A motorjet is a rudimentary type of jet engine which is sometimes called thermojet, a term which is more appropriately referenced to the nearly unrelated pulsejet engine. At the heart the motorjet is always an ordinary piston engine (hence, the term motor), but instead of this driving a propeller, it drives a compressor. The compressed air is channeled into a combustion chamber, where fuel is injected and ignited. The high temperatures generated by the combustion cause the gases in the chamber to expand and escape at high pressure from the exhaust, creating a thermal reactive force that drives the engine.

Motorjet engines provide greater thrust than a propeller mounted on a piston engine; this has been demonstrated in a number of different aircraft.

Motorjet research was nearly abandoned at the end of World War II as the turbojet was a more practical solution to jet power as it used the jet exhaust to drive a gas turbine, providing the power to drive the compressor without the additional weight of a piston engine that generated no thrust.

  • The first application of the motorjet principle was by Henri Coandă in his Coanda-1910 aeroplane (1910).
  • NACA engineer Eastman Jacobs was actively pursuing thermojet research in the early 1940s for a project that came to be known as Jake's jeep but which was never completed as turbojet technology overtook it.
  • Japanese engineers developed the Tsu-11 engine to power Ohka kamikaze aircraft as an alternative to the rocket engines that these aircraft were then using.
  • The Soviet Mikoyan-Gurevich I-250 (N) designed in 1944 used a piston engine to drive both a propeller at the nose of the plane, and a compressor leading to a jet exhaust at the tail.
