Front look at the Twin Cyclones on the North American B-25J Mitchell, Tondelayo from the Collings Foundation.

In 1935, Curtiss-Wright began work on a more powerful version of their successful R-1820 Cyclone 9. The result was the R-2600 Twin Cyclone, with 14 cylinders arranged in two rows. The 1,600 hp R-2600-3 was originally intended for the C-46 Commando and was fitted to the CW-20A prototype, but a running change[clarification needed] led to the adoption of the 2,000 hp Pratt & Whitney R-2800 in its place. The Twin Cyclone engine went on to power several key World War II production aircraft including the B-25 Mitchell.

This plane is one of two that still flies with Buffalo Airways in Yellowknife NWT. They deliver food and supplies to 5 settlements and villages north of Yellowknife and do this 5 days a week. Getting a 50 hour check.

The Pratt & Whitney R-2800 Double Wasp is a two-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,804 in³ (46 L), and is part of the long-lived Wasp family.

The R-2800 is considered one of the premier radial piston engines ever designed and is notable for its widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade this already powerful workhorse, most notably water injection to give emergency power in combat.

Anzani 3-cylinder radial

From 1905 to 1915, Alessandro Anzani built a number of three-cylinder fan and radial engines, one of which powered Louis Blériot's 1909 cross-channel flight. An Anzani three-cylinder engine that powers a Blériot XI based in England is thought to be the oldest airworthy engine in the world.

BMW 114 Radial Diesel Engine

flyvertosset — Fri, 17 Dec 2010 07:37:22 GMT

The BMW 114 was a nine-cylinder air cooled radial engine intended for military aircraft use. Developed in 1935 from the BMW 132 with which it could be interchanged, work did not progress beyond experimental prototype engines.

BMW 132E Radial

flyvertosset — Fri, 22 Apr 2011 17:33:27 GMT

The BMW 132 was a nine-cylinder radial aircraft engine produced by BMW starting in 1933.

BMW took over the license for manufacturing air-cooled radial engines from US aircraft manufacturer Pratt & Whitney Aircraft Company on 3 January 1928. The nine-cylinder model Pratt & Whitney Hornet was initially manufactured virtually unchanged under the designation BMW Hornet. Soon BMW embarked on its own development. The result was the BMW 132 that went into production in 1933, which was essentially an improved version of the Hornet engine. A number of different versions were built. Aside from the carburettor designs used mainly in civilian aircraft, versions with direct fuel injection were manufactured for the German Luftwaffe. The engines had a displacement of 27.7 liters and generated up to 1,200 PS (880 kW)[citation needed], depending on model.

BMW 801D, Radial Aircraft Engine

flyvertosset — Wed, 19 Oct 2011 22:17:11 GMT

The BMW 801 was a powerful German air-cooled radial aircraft engine built by BMW and used in a number of German military aircraft of World War II. The engine's 14 cylinders were in two rows of seven cylinders each, the bore and stroke were both 156 mm (6.14 in), giving a total capacity of 41.8 litres (2,502 in³). The engine generated between 1600 and 2000 hp. The unit (including mounts) weighed from 1,010 to 1,250 kg and was about 1.29 m (51 in) across, depending on the model.

Like most German aero engines, the BMW 801D did not have a carburetor, but featured direct fuel injection. An additional feature on the BMW engine in the Fw 190 was the Kommandogeraet a hydraulic-electric unit that automatically adjusted engine fuel flow, mixture and timing with propeller pitch in response to throttle demand and also engaged the supercharger. Over 61,000 examples of the 801 were made, the largest number of any single German aviation radial engine design in World War II, and whose production total for the entire WW II German aviation industry was only exceeded by the liquid-cooled Junkers Jumo 211 inverted V-12 engine.

The BMW 801D engine made history once coupled to the Fw 190, an extremely successful aircraft. It was a perfect combination, ensuring Fwl90 ranks with the Supermarine Spitfire, Vought Corsair and North American Mustang as one of the best fighters of World War II.
