BMW 018

The BMW 018, with the Reich Air Ministry designation 109-018, was an early axial-flow turbojet engine project by BMW in Germany. The design began in 1940 and was generally similar to the BMW 003, but with a twelve-stage axial compressor, annular combustors and a three-stage turbine, for a thrust of 34.3 kilonewtons. It was 4,190 millimetres long, 1,252 millimetres in diameter and weighed 2,295 kilograms dry, a thrust-to-weight ratio of 1.52. Three engines were at various stages of completion at Stassfurt, but continuing efforts on the 003, Allied bombing and the liberation of France stopped official development in late 1944. BMW moved the examples to Bavaria on its own initiative, and in March 1945 its personnel destroyed the engines and components to keep them from Allied hands.
