Heinkel HeS 011

The Heinkel HeS 011 is a jet engine from the German manufacturer Heinkel. This engine should almost all designs of aircraft with jet engines that were developed towards the end of the war in the Third Reich, are equipped. So the engine was also provided for the Experimental Aircraft P.1101 Messerschmitt.

The HeS 109-011 was designed under the direction of Hans Joachim Pabst von Ohain with five compressor stages - the first stage in an axial type, the second as a radial compressor and the last three again as axial compressor. This arrangement was called diagonal construction. In contrast to most of the other jet engines of this time, such as the Jumo 004, an annular combustion chamber and no individual combustion chambers was used. The turbine was equipped with hollow turbine blades and cooled with compressor air.

The first prototypes were tested on the test bench at the beginning of 1944. However, problems with the complicated compressor delayed the construction. The project never got beyond the experimental stage. It was planned to continue a turboprop variant of the HeS 011 labeled HeS Heinkel 021 as a wave Comparison Performance 3300 PSe had been given.

A total of nine specimens have been built, all of which have been brought to the U.S. and tested there.
