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.)

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

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.

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. Although derived from the successful P-38 Lightning, the XP-58 was plagued by technical problems with its engines that eventually led to the pro ..., Vultee XP-68 Tornado, and the Republic XP-69.

Junkers Jumo 222
The Jumo 222 was a German high-power multiple-bank in-line piston aircraft engine from Junkers, designed under the management of Ferdinand Brandner of the Junkers Motorenwerke. Such was the projected performance of the engine compared to contemporary designs that many developments of wartime Luftwaffe piston-engined aircraft designs were based on it, at least as an option. These included the entire Bomber B program, which looked to replace all existing Luftwaffe bombers with a new twin-engine design that was larger, faster and more heavily armed than any aircraft in their inventory. The design failed to mature even after years of intensive development and several major design changes. The Bomber B program failed along with it, leaving the ''Luftwaffe'' with hopelessly outdated designs during the second half of the war. Only a small number of 222s were built, less than 300. They never left the prototype phase, but the design nevertheless continued appearing on proposals for ...

Dobrynin VD-4K
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, which m ...

Curtiss H-1640
The Curtiss H-1640 Chieftain was an unusual American 12-cylinder radial aero engine designed and built by the Curtiss Aeroplane and Motor Company in the mid-1920s.Gunston 1989, p. 46 Design and development The H-1640 was an air-cooled 12 cylinder two-row radial with the cylinder rows aligned rather than staggered as in most multi-row radials. One piece cylinder heads shared a single overhead camshaft and the propeller was directly driven. By aligning the cylinders the diameter of the engine was less than more conventional radial engines, and it was thought that the use of a Townend ring could make the engine more aerodynamically efficient than an inline engine. The engine first ran in 1927. The H-1640 was the first airworthy 'inline radial' and was sponsored for flight testing in a range of aircraft by the U.S. Government. Among the types selected were the Thomas-Morse XP-13 and the Curtiss XO-18. Cooling problems with the rear cylinders caused the project to be canceled wi ...
