Description
VL Pyörremyrsky was a war time development, with the aim to produce a fighter that would meet the performance of Messerschmitt Bf 109G-6, using a Daimler-Benz DB 605 engine and as much wooden structures as possible. Two prototypes were ordered from Valtion Lentokonetehdas in 1943 but only one was eventually completed and flown in 1945. Development and construction were delayed by the need to keep existing aircraft repaired and ready to fight.
The Pyörremyrsky was more agile and climbed better than the Bf 109G but wasnt quite as fast. That was to be expected because it was decided to pick a design proposal with more wing area.
The Pyörremyrsky prototype - PM-1 - flew 27 hours between 1945 and 1947. It was struck off charge in 1953, with a stipulation that it must be preserved. The restored aircraft is on display at the Finnish Air Force Museum.
