Tumansky M-90
The Tumansky M-90 was a prototype Soviet radial engine designed before World War II. It proved unreliable and incapable of reaching its designed output and was cancelled in 1944. Development The M-90 began development in the spring of 1939 under the leadership of S. K. Tumansky as a coupled version of the 9-cylinder Gnome-Rhône 9K, which was built under license as the M-75. Later, possibly after E. V. Urmin assumed leadership of the project, the cylinder-piston group of the Tumansky M-88 was adopted, although the cylinder ribbing area was increased.Kotelnikov, p. 156 The layout of the engine was completed by 15 August 1939 and the engineering drawing by 15 October. The first prototype began bench tests on 29 November 1939. A total of five prototypes were built in 1939 and another five in 1940. They could not reach the engine's specified power output and suffered from broken crankshafts, pinion shafts and crankcase In a piston engine, the crankcase is the housing that surro ...

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 added i ...

1930s Aircraft Piston Engines
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Nakajima Homare
The Nakajima Homare (誉, "praise" or, more usually, "honour") was an air-cooled twin-row 18 cylinder radial Japanese aircraft engine manufactured during World War II. Producing almost 2,000 horsepower, it was used widely by both the Imperial Japanese Army and the Imperial Japanese Navy. Given the Navy service designation NK9, the "Homare" was also given the company designation NBA, Army experimental designation Ha-45 (ハ45) or, Army long designation Nakajima Army Type 4 1,900 hp Air-Cooled Radial and, (coincidentally) unified designation code of Ha-45.Gunston 1989, p.105. Design and development Development of the Homare started in 1940, and certification was completed in 1941. It succeeded Nakajima's previous 14 cylinder Sakae (Ha-25) engine, which had its own forward seven cylinders staggered from the rear seven for efficient cooling. The design was exceptionally compact, with an external diameter of 118 cm, a mere 3 cm larger than the Sakae. With a bore and ...

Gnome-Rhône 18L
The Gnome et Rhône 18L was a French-designed twin-row 18-cylinder air-cooled radial engine. The 18L was a large step up in terms of displacement, power and number of cylinders. The majority of Gnome-Rhone engines were either 7, 9 or 14 cylinders. The engine proved not to be a success, and it was dropped in 1939 due to a poor power-to-weight ratio.

BMW 802
The BMW 802 was a large air-cooled radial aircraft engine, built using two rows of nine cylinders to produce what was essentially an 18-cylinder version of the 14-cylinder BMW 801. Although promising at first, development dragged on and the project was eventually cancelled to concentrate on jet engines instead. Design and development Soon after the 801 entered testing, BMW engineers turned to building much larger versions. One idea was to bolt two 801s back to back. Although seemingly a simple concept, the resulting, 83.5 litre displacement BMW 803 was in fact fantastically complicated. The power of the engine could only practically be used in extremely large propellers, or, as selected, a contra-rotating pair of propellers. This required a large gearbox on the front of the engine, which combined with the layout of the cylinders, left no room for airflow over the cylinders. This demanded the addition of liquid cooling. Another idea was to add more cylinders to the 801 design, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfa Romeo 135
The Alfa Romeo 135 Tornado was an Italian 18-cylinder radial engine designed by Giustino Cattaneo in 1934–1935. Design and development The Alfa 135 consists of two nine-cylinder radial rows, back to back, operating a two-throw crankshaft. Cattaneo left Alfa Romeo in 1936, leaving the development of the 135 to eng. Bossi and his staff, but without success. At the time of its first running in 1938 and 1939 it was one of the most powerful radial engines in the world, generating just less than on 100 octane fuel, but the standard fuel available was 87 octane, with which the 135 developed . Despite the obvious potential, this engine was affected by many reliability problems. Although many mechanical defects were addressed during testing, it suffered from overheating and vibrations so seriously that it was rejected from service. Up to 1944 approximately 150 were made, none of which were fitted in operational aircraft. Further development resulted in the Alfa Romeo 136, but this re ...

Tumansky
Sergei Konstantinovich Tumansky (russian: Серге́й Константинович Туманский; – 9 September 1973) was a designer of Soviet aircraft engines and the chief designer in the Tumansky Design Bureau, OKB-300. He worked in TsIAM (1931–38 and in 1940), and at the aircraft-engine plant N 29, in Zaporozhye. He also worked as a substitute main designer in OKB A.A. Mikulin beginning in 1943.

Motor Sich
The Motor Sich Joint Stock Company ( uk, АТ «Мотор Січ») is a Ukrainian aircraft engine manufacturer headquartered in Zaporizhzhia. The company manufactures engines for airplanes and helicopters, and also industrial marine gas turbines and installations. Overview Motor-Sich currently produces the Ivchenko Progress D-18 turbofan which powers variants of the Antonov An-124 and An-225 freighters, although the Ivchenko Progress D-36/ Ivchenko Progress D-436 series remain the highest production-rate engines in the CIS. Motor Sich inherited some of the former Soviet Union's aero engine manufacturing capabilities. It produces turbofan, turboprop and rotary-wing turboshaft engines that power aircraft in Russian service, such as Mi- and Ka-series military helicopters. In 2017 Beijing's Skyrizon Aviation purchased a 41% holding in Motor Sich. Skyrizon Aviation had agreed to first invest $250 million in the Ukrainian Zaporizhzhia plants and help Motor Sich to set up a new ...

Crankcase
In a piston engine, the crankcase is the housing that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder(s). This design of the engine does not include an oil sump in the crankcase. Four-stroke engines typically have an oil sump at the bottom of the crankcase and the majority of the engine's oil is held within the crankcase. The fuel/air mixture does not pass through the crankcase in a four-stroke engine, however a small amount of exhaust gasses often enter as "blow-by" from the combustion chamber. The crankcase often forms the lower half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals. An ''open-crank'' engine has no crankcase. This design was used in early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
