Engines On UFO's in GERMANY

BMW (who was to provide the turbojets for Heinkel's jets) started work on a design very similar to Schriever's Flugkreisel but utilizing the company's own BMW 003 jet engines. These machines, called "Flugelrads" (Winged Wheels) were not true disc aircraft but jet autogyros that used a standard BMW 003 with a Strahlrohr (Jet pipe) deflector to power a multi-blade disc rotor.These craft were built on a much smaller scale than Schriever's Flugkreisel so work proceeded from 1941-45 with construction of prototypes beginning in 1943. Instability, however, was never really solved in the earlier designs. Only one disc, a BMW Flugelrad II V-2 (or V-3) possibly achieved flight in April 1945. Schriever's own design began to take shape in 1942 and flew in 1943. It flew under jet power provided by three attached special kerosene-burning engines driving the disc rotor as well as two kerosene jets attached to the body for forward thrust and horizontal stability.
