BMW 018
Type	Turbojet
National origin	Germany
Manufacturer	BMW
Number built	3
Developed from	BMW 003

Design

The 018 design was begun in 1940. It was generally similar to the BMW 003, but had a twelve-stage axial compressor and three-stage turbine, for a thrust of 34.3 kN (7,700 lbf).[1]

Three engines were at various stages of completion at Staßfurt, but due to continuing efforts toward protracted development of the 003 along with Allied bombing and the liberation of France, official 018 development was stopped in late 1944. On BMW's own initiative, it was decided that the existing 018 development examples would be moved to a pair of successive locations in Bavaria; to Kolbermoor to finish construction, and then move them to Oberwiesenfeld for testing. Despite this planning, the rapidly deteriorating war situation of March 1945 prompted BMW personnel to destroy the engines and their components in order to prevent them from falling into Allied hands.[2]

Das BMW 018 ist ein Turbinen-Luftstrahltriebwerk des deutschen Herstellers BMW, das aus dem Turboprop BMW 028 entwickelt wurde. Dabei wurden einfach die Luftschraube, das Luftschraubengetriebe sowie eine Turbinenstufe weggelassen, so dass das BMW 018 drei Turbinenstufen hatte. Der Treibstoffverbrauch sollte rechnerisch etwa 25 % niedriger sein als beim BMW 003. Das BMW 018 war das stärkste während des Zweiten Weltkrieges in Deutschland entwickelte Triebwerk. Der Bau eines Prototyps wurde kurz vor Kriegsende begonnen, konnte aber nicht fertiggestellt werden.
