Fokker D.XVI

The Fokker D.XVI, sometimes written D.16, was a sesquiplane fighter developed in the Netherlands in the late 1920s. It was a conventional single-bay sesquiplane with staggered wings braced with V-struts, an open cockpit and a fixed undercarriage with a tailskid; the wings had wood spars and ribs with a plywood covering and the fuselage was steel tube with fabric covering. Power came from an Armstrong Siddeley Jaguar 14-cylinder radial of 340 kW fitted with a Townend ring, giving a maximum speed of 320 km/h. The Royal Netherlands Army ordered 14 aircraft, with divided main undercarriage units in place of the prototype's cross-axle, and Hungary bought four with Bristol Jupiter engines. Evaluation aircraft went to China, Italy, Romania and the Royal Netherlands East Indies Army; the type also won a Romanian fighter competition without bringing orders. Fokker then built the similar D.XVII with an inline engine in its place.
