Klimov M-103
The Klimov M-103 is a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.Gunston 1989, p.90. Design and development The M-103 was a further development of the Klimov M-100 engine that was itself a licensed copy of the French Hispano-Suiza 12Ybrs. It differed from both engines in a number of aspects such as increased compression ratio, increased supercharger ratio, increased rpm's, strengthened cylinder blocks, a new crankshaft, a more aggressive camshaft, and flat bottomed cylinders. Developed in 1936 it was ready for testing in October 1936. The first two models failed testing due to cracked cylinder blocks and the engine was resubmitted for testing in 1937. After passing its trials it was cleared for production in 1938 and 11,681 were produced until 1942 at its factory in Rybinsk. The M-103 was followed by the M-105. Variants * M-103A - 148mm rather than 150mm bore cylinders. * M-103P - A ShVAK cannon fitted to fire through the engine v ...

Beriev MBR-7
The Beriev MBR-7 (sometimes Beriev MS-8) was a Soviet Union, Soviet short-range Surveillance aircraft, reconnaissance/bomber flying boat developed by the Beriev design bureau at Taganrog. Designed as a successor to the Beriev MBR-2, MBR-2 but it did not go into production due to lack of engines. Development The MBR-7 (Morskoy Blizhnii Razvedchik - naval short-range reconnaissance) was a similar configuration to the earlier Beriev MBR-2, MBR-2 but was a more advanced design. A mainly wooden cantilever shoulder-wing monoplane flying-boat. The Klimov M-103 inline piston engine was mounted on struts above the wing driving a pusher propeller. The pilot in an enclosed cockpit in the nose had access to a fixed forward-firing machine gun, the observer/gunner sat underneath a glazed canopy. The observers canopy slid forward to access a pintle-mounted ShKAS machine-gun. It had an excellent performance but due to the lack of supply of Klimov engines the decision was made to continue building ...

Klimov VK-107
The Klimov VK-107 was a V-12 liquid-cooled piston aircraft engine used by Soviet Union, Soviet aircraft during World War II. Development The VK-107 was developed from the Klimov M-105, M-105 and Klimov VK-106, VK-106. To achieve a greater power output, each cylinder now had four valves (two intake and two exhaust), crankshaft and camshafts were completely revised, and a new supercharger design was implemented. Although the engine could have been ready for production as early as 1942, the Soviet Union, Soviets' factories lacked the capacity to produce a brand new design. Thus, the less powerful Klimov VK-105PF and VK-105PF2 V12 engines were built instead. However, the appearance of Luftwaffe Messerschmitt Me 109, Messerschmitt Bf 109G with Daimler-Benz DB 605 engine in 1943 created an urgent demand for a more powerful engine. VK-107A was put into production in 1944 and was used on Yakovlev Yak-9, Yak-9U fighters. The engine was not well liked by either pilots or mechanics – it ha ...

Klimov VK-106
The Klimov M-106 was an experimental liquid-cooled V12 piston aircraft engine intended for Soviet aircraft during World War II.Gunston 1989, p. 90. Development With the VK-105PF exhausting the potential of the M-105, Klimov prolonged its development into new VK-106 engine from 1941. Since air combat on the Eastern Front took place primarily at low altitudes under the new engine was built specifically for peak performance at those altitudes with a reduced compression ratio and a single-speed supercharger. Static testing was carried out from 27 October till 9 November 1942. Although reliable and easily installed in M-105-powered aircraft, VK-106 did not enter production because its cooling problems were not solved. Like M-105P, VK-106P could house an autocannon An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-cali ...

Klimov M-100
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. Its design was based on the earlier, and somewhat smaller, 12X. The 12X did not see widespread use before the 12Y replaced it and became one of the most powerful French designs on the eve of the war. The 12Z was being designed but this was ended by the fall of France and the German occupation. The 12Y was produced under Hispano-Suiza licence in the Soviet Union as the Klimov M-100. This design led to the highly successful Klimov VK-105 series that powered the Yakovlev and Lavochkin fighters as well as the Petlyakov Pe-2 bomber. Licensed production of the early models was also undertaken in Czechoslovakia as the Avia HS 12Ydrs and in Switzerland as the HS-77. Design and developme ...

Hispano-Suiza 12Z
The 12Z, designated Type 89 by the company, was the final evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model had just entered production when France fell to the Germans during World War II. A small number were produced during the war but the German occupation government would not allow full-scale production to start. After the war small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development. Design and development The 12Z differed from the earlier 12Y primarily in the use of four valves per cylinder operated by dual overhead cams, as opposed to two valves operated by a single camshaft. This gave the cylinders considerably better volumetric efficiency and faster operation, raising the RPM from 2,400 to 2,700. The engine was also designed to run only on 100 octane fuel (instead of 87, which was common at that point) which allowed the compression ratio to rise from the 12Y's 5.8:1 to the 12Z's 6.75:1. ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including h ...

Yakovlev Yak-2
The Yakovlev Yak-2 was a short-range Soviet light bomber/reconnaissance aircraft used during World War II. It was produced in small numbers, and most of them were destroyed during the opening stages of Operation Barbarossa. Design and development The Yak-2 was initially known as the Ya-22, in the Yakovlev OKB numbering sequence, before it was redesignated as the Yak-2 in 1941. It was of mixed construction with wooden wings and center fuselage, duralumin forward fuselage, and steel tube framing in the rear fuselage with a wooden upper decking and fabric skin. The cockpit was at the very tip of the nose, but the navigator/gunner was in a compartment behind the trailing edge of the wing. The prototype was unarmed and no bomb shackles were fitted. It also lacked a radio and navigational equipment. It was, however, the fastest multi-engined aircraft in the Soviet Union, able to reach at , not least because it lacked heavy military equipment.Gordon, p. 132 Stalin ordered it into produc ...

Bolkhovitinov S
The Bolkhovitinov S (''Sparka'' – twin/joined (engine)) was a high speed bomber aircraft designed and built in the USSR from early in 1937. Other designations used at various times: BBS, BB, LB-S or SSS. Development The plane was conceived as a fast light bomber and reconnaissance plane. To obtain high speed and good aerodynamics, it was powered by two M-103 inline engines in tandem, driving two contra-rotating, coaxial three-blade propellers. The design had quite unusual look, with long fuselage nose and a cockpit moved rearwards, towards a double tail-fin. The wings had a fighter-like form and their span was rather short. The rear engine was geared to two high-speed shafts which passed either on side of the forward engine to drive the rear propeller gearbox, whilst the forward engine and gearbox drove the forward propeller via shaft through the middle of the rear propeller gearbox. The structure of the ''S'' was predominantly light alloy stressed skin, the wing having two s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
