Counter-rotating Propeller
Counter-rotating propellers, also referred to as CRP, are propellers which spin in opposite directions to each other. They are used on some twin- and multi-engine propeller-driven aircraft. The propellers on most conventional twin-engined aircraft spin clockwise (as viewed from behind the engine). Counter-rotating propellers generally spin clockwise on the left engine and counter-clockwise on the right. The advantage of such designs is that counter-rotating propellers balance the effects of torque and P-factor, meaning that such aircraft do not have a critical engine in the case of engine failure. Drawbacks of counter-rotating propellers come from the fact that, in order to reverse the rotation of one propeller, either one propeller must have an additional reversing gearbox, or the engines themselves must be adapted to turn in opposite directions. (Meaning that there are essentially two engine designs, one with left-turning and the other with right-turning parts, which compl ...

Messerschmitt Me 323
The Messerschmitt Me 323 ''Gigant'' ("Giant") was a German military transport aircraft of World War II. It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft to fly during the war. A total of 213 were made, 15 being converted from the Me 321. Development The Me 323 was the result of a 1940 German requirement for a large assault glider in preparation for Operation Sea Lion, the projected invasion of Great Britain. The DFS 230 light glider had already proven its worth in the Battle of Fort Eben-Emael in Belgium (the first ever assault by gliderborne troops), and would later be used successfully in the invasion of Crete in 1941. However, in order to mount an invasion across the English Channel, the Germans would need to be able to airlift vehicles and other heavy equipment as part of an initial assault wave. Although Operation Sea Lion was cancelled, the requirement for a heavy air transport capability still existed, with the fo ...

North American P-82 Twin Mustang
The North American F-82 Twin Mustang is the last American piston-engined fighter ordered into production by the United States Air Force. Based on the North American P-51 Mustang, the F-82 was originally designed as a long-range escort fighter for the Boeing B-29 Superfortress in World War II. The war ended well before the first production units were operational. In the postwar era, Strategic Air Command used the aircraft as a long-range escort fighter. Radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the Northrop P-61 Black Widow as all-weather day/night interceptors. During the Korean War, Japan-based F-82s were among the first USAF aircraft to operate over Korea. The first three North Korean aircraft destroyed by U.S. forces were shot down by F-82s, the first being a North-Korean Yakovlev Yak-11, Yak-11 downed over Gimpo International Airport, Gimpo Airfield by the USAF 68th Fighter Squadron.

De Havilland Hornet
The de Havilland DH.103 Hornet, developed by de Havilland, was a fighter aircraft driven by two piston engines. It further exploited the wooden construction techniques that had been pioneered by the de Havilland Mosquito. Development of the Hornet had started during the Second World War as a private venture. The aircraft was to conduct long range fighter operations in the Pacific Theatre against the Empire of Japan but the war ended before the Hornet reached operational squadron status. The Hornet entered service with RAF Fighter Command where it equipped several day fighter units and was commonly stationed in the British mainland. It saw combat in the Far East, being used as a strike fighter as part of the British military action taken during the Malayan Emergency. A naval carrier-capable version, the Sea Hornet, had been envisaged early on and was procured by the Fleet Air Arm of the Royal Navy. Development Origins In the autumn of 1941, de Havilland found that it had the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cessna 303
The Cessna T303 Crusader is an American six-place light twin-engined aircraft built by Cessna Aircraft Company. Production ceased in 1986. Design and development The original Cessna 303 Clipper was first flown on February 14, 1978;Taylor 1982, p.346. it was a low-wing four-seat Lycoming-powered twin-engined aircraft that would have competed with the Piper Seminole, Gulfstream American GA-7 Cougar, and Beechcraft Duchess. After market demand for four-place light twins declined, only one 303 Clipper was built before Cessna redesigned the aircraft as a six-seat twin. They also renamed the aircraft out of legal concern, since Pan Am Airlines held the trademark on the name "Clipper" in reference to their fleet aircraft. The new model, designated the T303 Crusader first flew on October 17, 1979, with the first deliveries being made in October, 1981. The T303 is an all-metal low-wing six-seat twin-engined aircraft with a retractable tricycle undercarriage. At the time, it was the ...

Beech Duchess
The Beechcraft Model 76 Duchess is an American twin-engined monoplane built by Beechcraft intended partly as a low cost introduction to twin-engine aircraft. Development Developed as Model PD289 (Preliminary Design 289), the prototype was unveiled on November 4, 1974, although it had first flown in September 1974. The Model 76 was designed as an economical twin-engine trainer for the Beech Aero Centers and to compete with the similar Gulfstream Cougar as well as the Cessna 310. The first production version flew on 24 May 1977, and the name "Duchess" was chosen through a company competition. Construction of the Duchess was set for a new factory built at the Liberal Division, with deliveries beginning early in 1978. Production of the Duchess continued until 1983, with no significant changes. A single example was tested with turbocharged engines in 1979, but did not proceed to production.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Benz DB 610
The Daimler-Benz DB 605 is a German aircraft engine built during World War II. Developed from the DB 601, the DB 605 was used from 1942 to 1945 in the Messerschmitt Bf 109 fighter, and the Bf 110 and Me 210C heavy fighters. The DB 610, a pair of DB 605s geared to turn a single output shaft that replaced the similar DB 606, was used in the A-3 and all A-5 variants of Germany's only operational heavy bomber, the Heinkel He 177A. License-built versions of the DB 605 were used in the Macchi C.205, Fiat G.55, Reggiane 2005 and some other Italian aircraft. It was also used in the Swedish SAAB B 18B and initially in the pusher-design SAAB J 21. Approximately 42,400 DB 605s of all kinds were built. Design and development The primary differences between the 605 and 601 were greater displacement, higher revolutions, higher compression ratio and a more powerful supercharger. Engineers determined that the cylinders could be bored out to a larger diameter without seriously affecting th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Benz DB 606
The Daimler-Benz DB 601 was a German aircraft engine built during World War II. It was a liquid-cooled inverted V12, and powered the Messerschmitt Bf 109, Messerschmitt Bf 110, and many others. Approximately 19,000 601's were produced before it was replaced by the improved Daimler-Benz DB 605 in 1942. The DB 601 was basically an improved DB 600 with direct fuel injection. Fuel injection required power to be taken off the drive shaft, but in return, improved low-RPM performance significantly and provided aerobatic performance in maneuvers where early versions of carburated engines like the British Rolls-Royce Merlin would lose power when the carburetor float bowl ran dry. The 601's fuel injection provided a significant boost in performance which its competitor, the Junkers Jumo 210, did not match for some time. By the time the fuel-injected 211 arrived, the 601 had already cemented its place as the engine for high-performance designs like fighters, high-speed bombers, and ...
