The Dutch Fokker T.VIII-W was a seaworthy floatplane during World War II . It was used for reconnaissance and as a torpedo bomber .
development
The T.VIII-W was due to a requirement of the Marine Luchtvaartmuseum service (MLD, Dutch naval aviation) for a succeeding pattern for the property in use outdated seaplanes, especially the T.IV . Project planning work began in 1937 and the first flight took place the following year. There were three main versions. The first series T.VIII-W / G ( G for mixed construction wood / metal) appeared from June 1939 and comprised a total of 19 machines. The T.VIII-W / M ( M for all-metal construction) was delivered in twelve copies. The last version was the T.VIII-W / C from 1940, again in mixed construction, but with larger dimensions and more powerful engines. Five of these machines had originally been ordered by Finland, but could no longer be delivered due to the German invasion and were later used by the German Air Force .
A total of 36 T.VIII-W were made.
commitment
Until the German troops marched in, the eleven aircraft that had been completed by then were used for reconnaissance and submarine hunting on the Dutch coast. The plan to send some machines to the Dutch East Indies was no longer realized.
At the beginning of the fighting, nine T.VIII-W moved to French bases on the Channel coast, where they flew patrol missions. Members of the Dutch government were flown to England by plane. On May 22, 1940, eight aircraft escaped to England, where they were combined in the 320th (Dutch) Squadron of the RAF and used against sea targets from Pembroke Dock / South Wales. Due to a lack of spare parts, these flights were discontinued after two months.
Five aircraft had been captured by the Germans, twenty others were still in production. After a test at the E -stelle Travemünde , these machines were used by the German Air Force over the North Sea for reconnaissance, sea rescue and submarine hunting until 1942.
construction
Conceptually, the T.VIII-W was a cantilevered middle-decker with braced light metal normal tail unit with fabric covering and a float landing gear. The fuselage was in three parts with an oval cross-section and consisted of a light metal bow, middle part made of wood and stern made of steel frame with fabric covering (T.VIII-W / G). The wing had two spars, bakelite ribs and plywood planking. In the T.VIII-W / M version, the rear fuselage and the wing were made of light metal.
The landing gear consisted of two single-stage , keeled floats made of corrosion-resistant Dural , each with six watertight compartments and a fuel reserve tank.
