The Mikulin AM-35 was a 1930s Soviet piston aircraft engine. [1] Derived from the AM-34FRN, the AM-35 entered production in 1940 and was used on the MiG-1 and MiG-3 World War II fighters as well as the Petlyakov Pe-8 heavy bomber.
The AM-35 was a high-altitude engine for fighters and bombers that evolved from the earlier AM-34FRN. Compared to the AM-34FRN it had an improved cylinder block, strengthened crankcase, higher compression ratio and a single-speed geared centrifugal supercharger with variable incidence blades. The AM-35 was developed in 1938 at the design bureau of Factory No. 24 now called the Salyut factory in Moscow. In March 1939 the AM-35 successfully passed its Factory tests and in April 1939 it passed its State tests. However, the VVS was not satisfied with the engine due to its rated power of 1,300 horsepower, which was 200 horsepower less than the specified requirement. The AM-35 also used a single-speed supercharger instead of the two-speed supercharger specified. In order to obtain higher performance a new version the AM-35A was designed with greater supercharger output and this was produced in large numbers at Factory No. 24 until the end of 1941 when the factory was evacuated to Kuybyshev. Although formally phased out of production small numbers of replacement AM-35A engines were produced at Kuybyshev during 1942-43 from AM-38 parts. In total 4,659 AM-35 and AM-35A engines were produced. [2]
A combination of factors led to the AM-35 being removed from production:

The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520.
The Petlyakov Pe-8 was a Soviet heavy bomber designed before World War II, and the only four-engine bomber the USSR built during the war. Produced in limited numbers, it was used to bomb Berlin in August 1941. It was also used for so-called "morale raids" designed to raise the spirit of the Soviet people by exposing Axis vulnerabilities. Its primary mission, however, was to attack German airfields, rail yards and other rear-area facilities at night, although one was used to fly the People's Commissar of Foreign Affairs Vyacheslav Molotov from Moscow to the United States in 1942.
The Mikoyan-Gurevich DIS was a prototype Soviet heavy fighter of World War II, envisioned to serve primarily in the escort fighter role. The service designation MiG-5 was reserved for the production version of the aircraft. Competing designs in the USSR included the Grushin Gr-1, Polikarpov TIS and Tairov Ta-3.
The Klimov M-105 was a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.
The Klimov M-106 was an experimental liquid-cooled V12 piston aircraft engine intended for Soviet aircraft during World War II.
The Klimov VK-107 was a V-12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.
The Mikulin AM-34 (M-34) was a Soviet mass-produced, liquid-cooled, aircraft engine of domestic design. Its initial development was troubled, but it eventually became one of the most successful Soviet aircraft engines of the 1930s. It was utilized on numerous aircraft, including the Beriev MBR-2, Tupolev TB-3, Tupolev TB-4, Tupolev ANT-20, Petlyakov Pe-8, Kalinin K-7, Polikarpov I-17, and Bolkhovitinov DB-A, as well as the G-5 and various prototype motor torpedo boats. A version of the maritime model was adapted for use in several prototype heavy tanks in 1939, although none was placed into production.
The Mikulin AM-38 was a 1940s Soviet aircraft piston engine. It was a further development of the Mikulin AM-35 design. The AM-38 was used on the Il-2 Shturmovik and Il-10 ground attack aircraft. The AM-38 was installed experimentally in a MiG-3 and tested during August 1941. A slight performance improvement was seen at low-altitude but the engine experienced overheating problems due to the cooling and oil systems remaining unchanged from the AM-35A.
The Mikulin AM-39 was a 1940s Soviet aircraft piston engine. Representing a high-output version of the AM-35A, AM-39 was used on the Mikoyan-Gurevich I-220 and Polikarpov ITP fighters, and the Tupolev SDB bomber.
The Mikulin AM-42 was a 1940s Soviet aircraft piston engine designed by Alexander Mikulin. Representing a high-output version of the AM-38F, the AM-42 was used in the Ilyushin Il-1 fighter, and the Il-8 and Il-10 ground attack aircraft.
The Mikulin M-17 was a Soviet-licensed copy of the German BMW VI V-12 liquid-cooled aircraft piston engine, further developed by Alexander Mikulin and used by Soviet aircraft and tanks during World War II. Production began in 1930 and continued through 1942. More than 27,000 were produced, of which 19,000 were aircraft engines while the rest were used in Soviet tanks of the period.

The Shvetsov ASh-73 was an 18-cylinder, air-cooled, radial aircraft engine produced between 1947 and 1957 in the Soviet Union. It was primarily used as the powerplant for the Tupolev Tu-4 heavy bomber, an unlicensed, reverse engineered copy of the American Boeing B-29 Superfortress.
Tupolev TB-6 was a proposal by the Tupolev Design Bureau in the 1930s for a super-heavy bomber. Had it been built, it would have been the biggest-ever Soviet bomber and the largest aircraft by wingspan of its time, nine feet short of the 320 foot span of the Hughes H-4 Hercules, although the Scaled Composites Stratolaunch is now the biggest plane by wingspan.
The Ilyushin I-21,, also known as TsKB-32, was a single-engined, single-seat fighter produced in the USSR in 1936-7 in response to a government specification.
The Charomskiy ACh-30 was a Soviet aircraft diesel engine developed during World War II. The initial version was not very satisfactory and it was cancelled when its factory was forced to evacuate in the autumn of 1941. Production was reinitiated in the summer of 1942 and continued until September 1945 to meet the need for an economical engine to power the Soviet long-range bombers like the Petlyakov Pe-8 and the Yermolayev Yer-2.
The Charomskiy M-40 was a Soviet turbocharged aircraft diesel engine developed during World War II. It was used in a few Petlyakov Pe-8 heavy bombers until August 1941 when it was removed, because it was unreliable at high altitudes. The engines were stored until 1944 when they were disassembled and their components were used in the closely related Charomskiy ACh-30B.
The Shvetsov M-71 was a Soviet radial engine built in small numbers during World War II. It was derived from the Shvetsov M-25, which was a license-built copy of the American Wright R-1820-F3 Cyclone engine.
The Mikulin AM-37 was a Soviet aircraft piston engine designed prior to Russia's entry into World War II. An improved version of the Mikulin AM-35 V-12 engine, it was only produced in small numbers because of its unreliability.
The Klimov M-120 was a Soviet prototype 18-cylinder liquid-cooled inline aircraft engine designed during the early years of World War II. Testing did not go well and it was cancelled in 1942.
