W.K.F. 80.05 Austria-Hungary
The first fighter of original design to be produced by W.K.F. (Wiener Karosserie- und Flugzeugfabrik Dr W v Gutmann), the W.K.F. 80.05 single-bay staggered triplane designed by Ing Alfred Gassner was completed in November 1917. Of wooden construction, it utilised a so-called Fischrumpf, or ‘‘Fish[-shaped] Fuselage”, of hexagonal cross section with plywood skinning, and the wings, which had I-type, aerofoil-section interplane struts, had ailerons on the upper and centre planes only. The W.K.F. 80.05 was powered by a 200 hp Austro-Daimler six-cylinder inline water-cooled engine and provision was made for an armament of twin synchronised Schwarzlose machine guns. Forward view from the cockpit was extremely limited by the very shallow cabane and the radiator bracing, and only limited flight testing of the sole W.K.F. 80.05 prototype was undertaken.
