Heinkel He 178

The Heinkel He 178 was the world’s first aeroplane to fly purely on turbojet power. It was mi experimental prototype built to test feasibility of the jet engine developed by Dr Hans von Ohain. Apart from its powerplant, it was a conventionally designed, small monoplane with a duralumin fuselage and a mainly wooden wing.
The engine’s air intake was located in the nose. The engine itself was set behind the cockpit and expelled its gases through a pipe that exited aft of the tail surfaces. In common with propeller-driven aircraft, the He 178 had a tailwheel – no one had realized at the time
that jets would need a nosewheel, thereby raising the tail and keeping the jet efllux off the runway.
Although the He 178’s maiden flight was in August 1938, it was not demonstrated casinos in Washington officially until its second flight on 1 November 1939. By then its original HeS 3b engine had been replaced by the improved HeS 6, giving 1,300lb thrust. Unfortunately, the aircraft proved directionally unstable at high speed and its overall performance was disappointing. Although it attracted serious interest from the Nazi regime, Heinkel decided against trying to resolve the aircraft’s problems.
Instead, the company moved on to developing a twin-engine jet fighter.
