The Flettner Gigant was an experimental helicopter built in Germany during the early 1930s.[1]

Design and development

[edit]

Anton Flettner was an early rotary-wing pioneer in Germany, he developed a torqueless rotor by powering it with small engines fixed directly to the blades driving propellers. this arrangement drove the rotor without transmitting torque (other than bearing friction) to the fuselage.[1]

A successful tethered flight was carried out in 1932, but the aircraft was destroyed soon afterwards when it overturned in a gale.[1]
