VL Tuisku
The VL Tuisku (English: Blizzard or Snowstorm) was a Finnish trainer aircraft designed in the 1930s. It was a two-seat, single-engined biplane with a welded steel framework, covered with fabric. 30 were produced for the Finnish Air Force and served from 1935 to 1949. Design and development Arvo Ylinen, who was the chief designer at the State Aircraft Factory ('' Valtion lentokonetehdas'', abbreviated VL) led a project to create a new trainer aircraft for the Finnish Air Force. A prototype was built in 1933 and it was first flown on January 10, 1934 by lieutenant U.E. Mäkelä. Series production began one year later in 1935 - 30 aircraft were built over a period of two years. Operational history Three different versions of the aircraft were made: a maritime, a pilot training and a reconnaissance training version. Examples were attached to all Finnish Air Force squadrons until 1949, with the identification codes TU-149 to TU-179. The FAF ordered 12 planes in February 1935, eight ...

Trainer (aircraft)
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valtion Lentokonetehdas
''Valtion lentokonetehdas'' (State aircraft factory) was a Finnish aircraft manufacturing company that was founded on 23 February 1928 from the IVL or I.V.L. factory (Ilmailuvoimien lentokonetehdas, Finnish Air Force Aircraft Factory), founded in 1921. The company was transferred from being subordinate to the Finnish Air Force to being subordinate to the Ministry of Defence. The company, and its products were named with the prefix VL. Island factory The company began its production at Suomenlinna and Santahamina in Helsinki. The factory did not have an airport, only the sea and sea ice could be used for take-off and landing. Most of the aircraft built in Helsinki were seaplanes. In Helsinki the aircraft built were small compared to the Bristol Blenheim bombers built under licence in the late 1930s. Much of the final assembly was done outdoors. The company was looking for a new production facility further away from the Soviet Union. Helsinki was seen as a bad location for an a ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be ...
