Fokker D.XVII (sometimes written as Fokker D.17), was a 1930s Dutchsesquiplane developed by Fokker. It was the last fabric-covered biplane fighter they developed in a lineage that extended back to the First World WarFokker D.VII.
Problems with severe vibration in the Armstrong Siddeley Jaguar radial engine on the Fokker D.XVI resulted in one being converted to use a normally aspirated Шаблон:CvtCurtiss Conqueror V-1570 V-twelve, becoming the prototype for the D.XVII.
Production versions were fitted with a Шаблон:CvtRolls-Royce Kestrel, while one aircraft was built with a Шаблон:CvtLorraine Pétrel and another was built with a Шаблон:CvtHispano-Suiza 12Xbrs for comparison purposes.[1][2]
Structure was standard for Fokkers throughout the 1920s. The sesquiplane's fuselage was welded steel tube with fabric covering and the wings were made with wood spars and ribs covered with plywood.[3]
Operational history
On 18 January 1935, Lieutenant René Wittert van Hoogland set a Dutch high-altitude record in a Fokker D.XVII of Шаблон:Cvt while using oxygen and high octane fuel.
By May 1939, the aircraft was obsolete and remaining examples were transferred to the LVA Flying School for fighter pilot training however they saw some action during the Battle of the Netherlands, escorting Fokker C.Vs and C.Xs on bombing missions.[2]
When the Netherlands surrendered to the Germans, all surviving aircraft were burnt.[2]
Airspeed Ltd. had a licence to build Fokker aircraft in England and considered making the Fokker D.XVII fighter for Greece under the designation Airspeed AS.17. Greek government interest was constrained by currency concerns. Nevil Shute and a Fokker representative "who was well accustomed to methods of business in the Balkans" spent three weeks in Athens but they did not close the deal.[4][5]
