| Status | Unbuilt Design |
The Porsche 005 (full RLM designation 109-005) was small single use turbojet design intended to power a long range version of the V1 flying bomb.[1][2][3] At the end WW2, the design of the Porsche 005 turbojet had not been finalized and no parts were constructed.[3]
Design and Development
The Argus As 014 pulsejet used in production V1 flying bombs was simple to build but relatively fuel inefficient. Design of the Porsche 005 began in late 1944 with the aim of proving a more fuel efficient engine for the V1 flying bomb allowing for greater ranges. The use of the Porsche 005 turbojet was projected to increase the range of the V1 flying bomb from 240km to 700km and allow for launching without the need for a ramp.[3]
During the last months of WW2 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]
