This project was studied along with the FW "Triebflugel" design and utilized the same lift conception. The Flakmine V-7, called "Feuerball", was formed of the central body storing fuel, explosive (between 250 and 500kg) and vapourization system. A free spinning rotor with four Pubst jets was mounted around this body. The ignition and initial rotation was performed on the launch platform. After reaching the circular speed of 200m/sec the blades were tilted to a +3° angle and the machine took off into the air. When reaching the formation of the Allied bombers the Flakmine would have been detonated by means of infrared, radar or acoustic fuse. There's no doubt that such a weapon might have been highly effective against the Allied bombing raids. V-7 "Feuerball" data: T/O weight...................2000 kg Height .........................2.5 m Rotor diameter .........7 m
