Shvetsov M-11
The Shvetsov M-11 is a five-cylinder air-cooled radial engine, radial aircraft engine produced in the Soviet Union between 1923 and 1952.Gunston 1989, p.158. Design and development The Shvetsov M-11 was designed under a 1923 competition in the Soviet Union for a new engine to power trainer aircraft. It is a single-row five-cylinder air-cooled radial engine, radial piston engine with aluminum cylinder heads. Like the American Kinner B-5 5-cylinder radial of similar size, the M-11 had individual camshafts for each cylinder, operating the pushrods, rather than a single central cam ring. The initial versions of the M-11 suffered from a short Time between overhaul, service life of only 50 hours. The basic M-11 engine had a power output of 100 hp (73 kW), the newer M-11D variant was higher at 125 hp (92 kW). The ultimate version, M-11FR, introduced in 1946, increased power output to 160 hp at 1,900 rpm on takeoff and 140 hp at cruise and had provisions for ...

VEF I-17
VEF I-17 was a Latvian trainer aircraft (intended also as a fighter) designed in 1939 by Latvian aircraft designer Kārlis Irbītis. The I-17 was test flown in early 1940 and almost immediately accepted by Latvian Air Force. It was produced by the VEF factory in Riga. Design and development In 1939 Latvia ordered 39 Hawker Hurricane fighters from United Kingdom, thus there was a need for monoplane pilots in Latvia. For this purpose, Irbītis designed the VEF I-17 among other trainer aircraft. Due to the start of Second World War in September 1939, the British Hawker Hurricanes never arrived in Latvia which induced the Latvian Air Force to encourage Latvian aircraft development instead. Due to the pressures of the war, the I-17 prototype was accepted almost without testing and serial production started. Six units of the I-17 were built and there was an order for another six, but that was halted following the Soviet occupation of Latvia in June 1940. After the occupation, the ...
