Focke-Achgelis Fa 330 Bachstelze
Photographed at the Deutsches Museum, Munich, on 1 September 2010. See also picture #10475
Dating from 1942, the Bachstelze (= Wagtail) was pulled into the air like a kite by a submarine running at the surface. Around 200 were built. However, only a few were actually used because they considerably increased the time required for a dive. It took the kite eleven minutes to descend from a height of 200 m.
Altitude and direction control took place by tilting the rotor head. The angle of incidence of the three-blade rotor could not be changed.
