Udet U 11 Kondor
The Udet U 11 Kondor was a German four-engined airliner designed and built by Udet Flugzeugbau, only one was built.[1][2]
Design and development
The U 11 Kondor was an open-cockpit, metal-fuselage, wooden high-wing monoplane powered by four 100 hp (75 kW) Siemens-Halske Sh 12 piston engines in shaft-driven pusher configuration.[1] It had a crew of three and room for eight passengers with a dangerously close clearance between the pusher propellers and rear passenger door, which caused one fatality.[1] The aircraft was tested by Harry Rother near Munich, finding a tail-heavy condition which required addition of larger control surfaces. The only U 11 was first flown on 19 January 1926 and was refused by Deutsche Luft-Reederei then purchased by Deutsche Luft Hansa, crashing on its delivery flight. The cost to develop and produce the prototype was a factor in the collapse of the company, which was then taken over by Bayerische Flugzeugwerke.[1]
