Unpowered rotary wing aircraft for use from submarines, Germany, 1938

[Technical Data] [Expo/Images] - [ Focke Achgelis] [ Helicopters 1919-1938] [ Navy and carrier based aircraft 1919-1938]

Description:

By the low height of submarines, the observation radius of subs was
very limited. The Bachstelze should carry an observer into a better
observation position, so the radius was greatly enhanced. The
Bachstelze is without propulsion so it was dragged by the U-boat
very much the same than today's paraglider being towed by boats
at the beach. The Bachstelze's design allowed the crew to take her
apart and stow it in the U-Boat. Every part was sized so it could pass
the small hatches. A disadvantage was that when the U-Boot was
attacked while the Bachstelze was outside, it's pilot and the apparatus
was lost.
