Around the world, a number of projects have used small gas turbines for propulsion of gliders. They usually come from the world of micro-turbines for radio controlled aircraft, and are not certified.
Since April 2008, M & D Flugzeugbau is a gas turbine development company for gliders or powered sailplanes, certified by EASA.
TJ-42 has been studied to provide the perfect balance between optimum climbing and rapid cruising. Pilots can choose between climbing at two metres per second at 135 km/h and a solid 200 km/h cruising speed.
The jet engine requires no aviation fuel. Instead, it’s fuelled by regular diesel.
