Walther HWK 109-500

From PlaneSpottingWorld, for aviation fans everywhere

The Walther HWK 109-500 is a liquid fuelled rocket motor developed by Germany during the Second World War.

The 109-500 is a Starthilfe (take-off assist) motor in a pod, able to produce 500kg (1100 lb) thrust for thirty seconds. After the fuel was expended, the pod was jettisoned and it returned to earth by parachute.[1]

It entered service in 1942, and some 6000 were built, by Heinkel.[2]
