The Porsche 005 (full RLM designation 109-005) was a small, single-use turbojet design intended to power a long-range version of the V-1 flying bomb.[1][2][3] At the end of World War II, the design of the Porsche 005 turbojet had not been finalised and no parts had been constructed.[3]
Design and development
The Argus As 014 pulsejet used in production V-1 flying bombs was simple to build but relatively fuel inefficient. Design of the Porsche 005 began in late 1944 with the aim of providing a more fuel efficient engine for the V-1 allowing for greater ranges. The use of the Porsche 005 turbojet was projected to increase the range of the V-1 from 240 km (149 mi) to 700 km (435 mi) and allow launching without ramps.[3]
During the last months of World War II the Porsche 005 project was being led by Dr Max Adolf Mueller,[3] who had worked on jet engine projects for both Junkers and Heinkel.[3][4] Dr Mueller was taken into captivity at the end of the war, and later prepared a drawing of the Porsche 005 for American investigators. Post-war, Porsche did not continue work on gas turbines or jet engines.[3]
