The VL Tuisku was a Finnish trainer aircraft from the 1930s.
History and construction
Arvo Ylinen , chief designer of the state aircraft factory Valtion lentokonetehdas , was the project manager for the development of this aircraft for the Finnish Air Force .
The first prototype was built in 1933 and first flown by Lieutenant UE Mäkelä on January 10, 1934. Series production began a year later. 30 planes were built within two years. These were given the identification codes TU-149 to TU-179. The Tuisku was the first Finnish aircraft with a welded tubular steel frame.
Three versions of this aircraft were built, one with floats, one for pilot training and one for scout training. The aircraft was used by all Finnish squadrons until 1949.
A preserved tuisku with the name "Sokeri-Sirkku", (TU-178) is exhibited in the Aviation Museum in Vantaa (Suomen Ilmailumuseo). The hull of another (TU-169) has been preserved and is kept in the museum's warehouse. Another restored tuisku stands in front of the old state aircraft factory in Tampere.
