The Kondor D 2 was a German single seat, biplane fighter aircraft designed and built close to the end of World War I.
Design and development
[edit]The Kondor D 2 was a basically a redesign of the D 1, which had proven underpowered in flight tests. Like the D 1, the D 2 was a single-seat biplane of wooden construction, powered by a 110 hp (82 kW) Oberursel Ur.II rotary engine and armed with two 7.92 mm (0.312 in) LMG 08/15 Spandau machine guns. However, the D 2 differed from its predecessor in having equal span wings with a two-spar lower wing with parallel inter-plane struts. The first flight of the Kondor D 2 took place in May 1918, in time for the second D-type competition at Aldershof in June 1918. Oberleutnant Hermann Göring praised the aircraft's flying qualities, but criticised the poor performance, consequently the D 2 was not ordered into production.[1]
Confusion reigned after the competition, up to the present day, because the Idflieg referred to the two D 2 prototypes as the D.I and D.II during the competition, which were actually fictitious designations.[1]
The first D 2 prototype had ailerons on the upper wings, while the second D 2 prototype had ailerons on both upper and lower wings.[citation needed]
