DF-1, D.D.Fedorov

20k b/w drawing "History of aircraft construction in the USSR", Vol.1 p.342

Two-seat long range reconnaissater, designed and built in extremely hard economical conditions right after the ('official') end of the Civil War. Project started in November 1920 in Sympheropol GAZ-15 (former Anatra) and received strong public support.

DF-1 had unconventional swept-back (20°) outer wing panels. The engine was a restored German Maybach, 'borrowed' from downed Zeppelin.

Despite designer's death (February 22, 1922) construction was finished, and flight tests took place in May-June 1922. Aircraft was easy on take off and fun to fly. Despite very strong structure, trials were interrupted after hard landing (pilot's error) when landing gear was damaged.

Plans to repair damaged aircraft and build the second DF-1 were scrapped when the factory was closed (August 1922???).
