Fokker D.V
The Fokker D.V was a biplane fighter designed by the Fokker Aircraft Company during the First [World War] for the Imperial German Army's Imperial German Air Service and the Imperial German Navy's Naval Air Service. Developed from the Fokker D.II, the aircraft was designed as a fighter trainer in 1916, although it also saw service in the fighter role in rear areas.
Design and development
After the disappointing performance of his D.I through D.IV, Fokker resolved to produce a smaller, lighter rotary-powered design. The new prototype, designated M.22, was a development of the earlier single-bay D.II prototype with a Oberursel U.0 rotary engine which Fokker had produced for the Austro-Hungarian Air Service as the B.II.The prototype featured a swept-back upper wing to improve pilot view and it was fitted with ailerons rather than the wing warping used by the earlier aircraft. To reduce the M.22's drag, a circular cowling completely enclosed the Oberursel U.I engine and the propeller was fitted with a spinner. To smooth the transition between the circular cowling and the straight sides of the fuselage, stringers were added to the forward fuselage. The aircraft proved to be highly maneuverable and it was ordered the M.22 into production as the D.V in three batches totaling 300 aircraft in October 1916.
