Dobrynin VD-3K
The Dobrynin VD-4K was a Soviet six-bank, 24-cylinder, turbo-compound, inline engine developed after the end of World War II. It was superseded by turboprop engines before it could be widely used. Development The VD-4K, originally designated as the M-253K, was a development of the post-war VD-3TK (M-251K) engine. Like Nazi Germany's experimental Junkers Jumo 222 multibank wartime engine, the VD-4K had six monobloc banks, each with four liquid-cooled cylinders. However, the VD-4K had a larger displacement figure — at nearly 59.5 litres — than any planned or tested development of the German powerplant; itself only planned to have a top displacement figure of 55.5 litres, with a 145 x 140 mm bore-stroke figure for each cylinder in its planned 222C/D version. The VD-4K utilized a trio of blow-down exhaust, also known as power-recovery, turbines were fitted between the cylinder banks, and a geared centrifugal supercharger and a turbocharger were fitted to the engine itself, w ...

Turbo-compound Engine
A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines, the energy is instead sent to the output shaft to increase the total power delivered by the engine. The turbine is usually mechanically connected to the crankshaft, as on the Wright R-3350 Duplex-Cyclone, but electric and hydraulic power recovery systems have been investigated as well. As this recovery process does not increase fuel consumption, it has the effect of reducing the specific fuel consumption, the ratio of fuel use to power. Turbo-compounding was used for commercial airliners and similar long-range, long-endurance roles before the introduction of turbojet engines. Examples using the Duplex-Cyclone include the Douglas DC-7B and Lockheed L-1049 Super Constellation, while other designs did not see production use. Concept Most piston engines have a hot exhau ...

Tupolev Tu-4
The Tupolev Tu-4 (russian: Туполев Ту-4; NATO reporting name: Bull) is a piston-engined Soviet strategic bomber that served the Soviet Air Force from the late 1940s to mid-1960s. It was reverse-engineered from the American Boeing B-29 Superfortress. Design and development Toward the end of World War II, the Soviet Union saw the need for a strategic bombing capability similar to that of the United States Army Air Forces. The Soviet VVS air arm had the locally designed Petlyakov Pe-8 four-engined "heavy" in service at the start of the war, but only 93 had been built by the end of the war and the type had become obsolete. The U.S. regularly conducted bombing raids on Japan, from distant Pacific forward bases using B-29 Superfortresses. Joseph Stalin ordered the development of a comparable bomber. The U.S. twice refused to supply the Soviet Union with B-29s under Lend Lease. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950s Aircraft Piston Engines
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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.

Wright R-2160 Tornado
The Wright R-2160 Tornado was an experimental 42-cylinder, 7-cylinder per row, 6-row liquid-cooled inline radial aircraft engine. It was proposed in 1940 with 2,350 hp (1,752 kW) for experimental aircraft such as the Lockheed XP-58 Chain Lightning The Lockheed XP-58 Chain Lightning was an American long-range fighter developed during World War II.

Daimler-Benz DB 604
The Daimler-Benz DB 604 was an experimental German 24-cylinder aircraft engine, which did not progress beyond the initial engine testing phase and was ultimately abandoned in 1942. Design and development The DB 604 was unique among the DB 600 series of aircraft engines by having its 24 cylinders arranged in an X, with four inline rows of six cylinders. The DB 604 was also unique amongst the X-24 engines, in that it was not conceived as a further development of existing Daimler-Benz aircraft engines such as the DB 601, DB 603 or DB 605, which themselves had been twinned-up as two separate powerplants sharing a new common gear reduction case at their front ends, into the 1.5-tonne dry weight DB 601-based "coupled" DB 606 in February 1937, the same-weight figured DB 605-based DB 610 by June 1940, and just slightly earlier, in March 1940, the 1.8 tonne approximate weight replacement for the DB 606 and 610, the DB 603-based DB 613 "power system" of nearly 3,500 PS output.

Armstrong Siddeley Deerhound
The Armstrong Siddeley Deerhound was a large aero engine developed by Armstrong Siddeley between 1935 and 1941. An increased capacity variant known as the Boarhound was never flown,Gunston 1989, p.18. and a related, much larger, design known as the Wolfhound existed on paper only. Development of these engines was interrupted in April 1941, when the company's factory was bombed, and on 3 October 1941 the project was cancelled by the Air Ministry. Design and development The Deerhound I was a triple-row, 21-cylinder, air-cooled radial engine design with the unusual feature of inline cylinder banks. Unlike earlier Armstrong Siddeley engines the Deerhound used overhead camshafts to operate its poppet valves, using one camshaft for each bank of three cylinders.Lumsden 2003, p.77. Flight testing began in 1938 using an Armstrong Whitworth Whitley II, serial number ''K7243'', during which cooling problems were encountered with the rear row of cylinders. This problem was solved by a 'r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Siddeley Hyena
The Armstrong Siddeley Hyena was a British aero engine developed by Armstrong Siddeley. Designed in the 1930s, it was an unusual experimental radial engine with inline cylinder banks. It was flown using an Armstrong Whitworth A.W.16 fighter aircraft as a test bed. Unresolved problems with cooling of the rear cylinders prevented the engine from going into production. Few details of this engine survive as company records were lost.Lumsden 2003, p.76. Armstrong Siddeley in-line radial engines The Hyena arrangement of cylinder banks arranged as a radial engine was continued with further designs, but with little commercial success, with only the Deerhound and Hyena being built. ;Hyena: 15 cylinders (5 banks of 3 cyl.) ;Terrier: 14 cylinders (7 banks of 2 cyl.) ;Deerhound: 21 cylinders (7 banks of 3 cyl.) ;Wolfhound: 28 cylinders (7 banks of 4 cyl.) ;Boarhound: 24 cylinders (6 banks of 4 cyl.) ;Mastiff: 36 cylinders (9 banks of 4 cyl.)

Napier Nomad
The Napier Nomad is a British diesel aircraft engine designed and built by Napier & Son in 1949. They combined a piston engine with a turbine to recover energy from the exhaust and thereby improve fuel economy. Two versions were tested, the complex Nomad I which used two propellers, each driven by the mechanically independent stages, and the Nomad II, using the turbo-compound principle, coupled the two parts to drive a single propeller. The Nomad II had the lowest specific fuel consumption figures seen up to that time. Despite this the Nomad project was cancelled in 1955 having spent £5.1 million on development, as most interest had passed to turboprop designs. Design and development In 1945 the Air Ministry asked for proposals for a new class engine with good fuel economy. Curtiss-Wright was designing an engine of this sort of power known as the turbo-compound engine, but Sir Harry Ricardo, one of Britain's great engine designers, suggested that the most economical comb ...
