The Spijker V.2, sometimes anglicized to Spyker V.2 or Spyker-Trompenburg V.2, was a low powered, tandem seat biplane designed and built for the Dutch government for pilot training towards the end of World War I. More than seventy were built.
Design[]
The Spijker V.2 was a conventionally laid out single engine tractor biplane. Its wings had constant chord and no sweep or stagger. It was a two bay biplane, with two pairs of parallel interplane struts on each side and two further pairs acting as a cabane between fuselage and the upper wing.[1] Ailerons were fitted to both upper and lower wings.[2] Over the fuselage was a semicircular cut out in the trailing edge of the upper wing to enhance the upward view from the rear seat. The tandem open cockpits were fitted with dual controls.[1]
The V.2 was powered by a 60 kW (80 hp) Thulin A (Le Rhône 9C) rotary engine,[3] driving a two blade propeller and enclosed by a 360° or 270° cowling. Its fuselage was built with wooden longerons and T-sectioned cross pieces braced with wire.[2] The conventional undercarriage was fixed, with mainwheels on a single axle supported at each end on V-form struts, cross braced. A tail skid completed the landing gear.[1]
Operational history[]
Because of the war in which the Netherlands remained neutral the European public did not see the V.2 until one of the first post-war air shows, the Eerste Luchtverkeer Tentoonstelling (First Air Traffic Exhibition) held in Amsterdam in August 1919. The V.2's ability to loop on a small engine was noted.[2] Seventy-eight V.2s were built for the Dutch government.[4] Fifty-eight of these were for the Army Aviation Group (LVA), eighteen for the Dutch Naval Aviation Service (MLD) and two for the KNIL. There were a significant number of fatal losses in both the LVA and MLD but the V.2s were flown by both services until 1924, when the MLD replaced their V.2s with Fokker S.3s; nine of their V.2s went to the LVA.[5]
