Dornier Do 417
The Dornier Do 417 was a twin-engine multirole combat aircraft. Developed in 1942, it resulted from the Luftwaffe's request for a medium bomber, a contest in which Dornier, Junkers, Heinkel, and Blohm & Voss competed. In the end, the Junkers Ju 188 was chosen by the Luftwaffe, and the Do 417 never entered production. Design and development The plans for the Do 417 were first presented to the RLM on January 22, 1943 in response to the Bomber B competition. It was intended to fill both the bomber and reconnaissance roles. It was to have a stepless cockpit housing three of the four crew, and was to be fitted with Kuto-Nase cable-cutters on the nose and along the leading edge of the wing to defend against barrage balloon A barrage balloon is a large uncrewed tethered balloon used to defend ground targets against aircraft attack, by raising aloft steel cables which pose a severe collision risk to aircraft, making the attacker's approach more difficult.

Multirole Combat Aircraft
A multirole combat aircraft (MRCA) is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses. Definition The term "multirole" was originally reserved for aircraft designed with the aim of using a common airframe for multiple tasks where the same basic airframe is adapted to a number of differing roles. The main motivation for developing multirole aircraft is cost reduction in using a common airframe. More roles can be added, such as aerial reconnaissance, forward air control, and electronic-warfare aircraft. Attack missions include the subtypes air interdiction, suppression of enemy air defense (SEAD), and close air support (CAS). Multirole has also been applied to one aircraft with both major roles, a primary air-to-air combat role, and a secondary role like air-to-surface attack. However, those designed with an emphasis ...

MG 151 Cannon
The MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II. Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe Fighter aircraft, fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft. Salvaged guns saw post-war use by other nations. Development and wartime history (MG 151/20) The pre-war German doctrine for arming single-engine fighter aircraft mirrored that of the French. This doctrine favoured a powerful autocannon mounted between the cylinder banks of a V engine and firing through the propeller hub, known as a ''moteur-canon'' in French (from its first use with the Hispano-Suiza 8#Variants, Hispano-Suiza HS.8C engine in World War I, on the SPAD S.XII) and by the cognate ''Motorkanone'' in German by the 1930s. The weapon preferred by the French in this role was the most powerful 20mm Oerlikon of the time, namely the Oerlikon 20 mm cannon, FFS model, b ...

North American B-25 Mitchell
The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber. Design and development The Air Corps issued a specification for a medium bomber in March 1939 that was capable of carrying a payload of over at North American Aviation used its NA-40B design to develop the NA-62, which competed for the medium bomber contract. No YB-25 was available for prototype service tests. In September 1939, the Air Corps ordered the NA-62 into production as the B-25, along with the ...

Mitsubishi Ki-67
The Mitsubishi Ki-67 ''Hiryū'' (飛龍, "Flying Dragon"; Allied reporting name "Peggy") was a twin-engine heavy bomber produced by Mitsubishi Aircraft Company and used by the Imperial Japanese Army Air Service and Imperial Japanese Navy Air Service in World War II. Its Army long designation was "Army Type 4 Heavy Bomber" (四式重爆撃機). Japanese Navy variants included the P2M and Q2M. Design The Ki-67 was the result of a 1941 Japanese army specification for a successor to the Nakajima Ki-49 "storm dragon". This new aircraft was specified to be a high-speed twin-engined heavy bomber suitable for possible conflicts with the Soviet Union over the Manchuria-Siberia border, and unlike many Japanese warplanes, was required to have good defensive armament and the ability to survive heavy battle damage. It was also required to be highly maneuverable allowing it to carry out dive-bombing attacks and escape at low level. The Ki-67 was designed by a team led by Kyūnojō Ozawa, chie ...

Martin B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual the aircraft would often stall and crash.Ethell 1995, p. 24 ...

Dornier Do 317
The Dornier Do 317 was a prototype German medium bomber of World War II. Design and development In June 1940, Dornier produced plans for a further development of the Do 217, which would have a pressurized cabin and more powerful engines (DB 604, BMW 802 or Jumo 222). Designated Do 317, it was one of the proposals submitted to the RLM for the " Bomber B" project. Two versions of the Do 317 were proposed: the simplified Do 317A, powered by two DB 603A engines and featuring conventional defensive armament, and the more advanced Do 317B with the heavy, 1.5 tonnes apiece, counter-rotating DB 610A/B "power system" engines, remotely aimed ''Fernbedienbare Drehlafette'' (FDL)-style gun turrets, higher bombload, and an extended wing. The "Bomber B" project was partially based off of improved engines, however its engines such as the DB 604 and Jumo 222 failed to reach full production. As a result, the Do 317 had to use the less powerful engines. Six prototypes of the Do 317A were ordered, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Do 215
The Dornier Do 215 was a light bomber, aerial reconnaissance aircraft and later a night fighter, produced by Dornier originally for export, but in the event most served in the ''Luftwaffe''. Like its predecessor, the Dornier Do 17, it inherited the title "The Flying Pencil" because of its slim fuselage. The successor of the Do 215 was the Do 217. Design and development The Do 17 fast bomber elicited renewed interest from foreign air forces (after the initial Do 17K series production). In July 1937, Dornier therefore prepared a pre-series Do 17 Z-0 as a demonstrator for export customers. It was given the civil registration D-AAIV. While this aircraft was essentially identical to the production Do 17Z, the assigned the designation Do 215 to the export version. However, in spite of the Do 215 being designated as an export version, many Do 215s were used by the Luftwaffe. The first prototype, Do 215 V1, retained the nine-cylinder Bramo 323 ''Fafnir'' radial engine of the Do 17Z. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Do 17
The Dornier Do 17 is a twin-engined light bomber produced by Dornier Flugzeugwerke for the German Luftwaffe during World War II. Designed in the early 1930s as a ''Schnellbomber'' ("fast bomber") intended to be fast enough to outrun opposing aircraft, the lightly built craft had a twin tail and "shoulder wing". Sometimes referred to as the ''Fliegender Bleistift'' ("flying pencil"), it was popular among its crews due to its handling, especially at low altitude, which made the Do 17 harder to hit than other German bombers. The Do 17 made its combat debut in 1937 during the Spanish Civil War, operating in the Condor Legion in various roles. Along with the Heinkel He 111 it was the main bomber type of the German air arm in 1939–1940. The Dornier was used throughout the early war, and saw action in significant numbers in every major campaign theatre as a front line aircraft until the end of 1941, when its effectiveness and usage was curtailed as its bomb load and range were limi ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

Daimler-Benz DB 603
The Daimler-Benz DB 603 was a German aircraft engine used during World War II. It was a liquid-cooled 12-cylinder inverted V12 enlargement of the DB 601, which was in itself a development of the DB 600. Production of the DB 603 commenced in May 1942, and with a 44.5 liter (44,500 cc) displacement figure, was the largest displacement inverted V12 aviation engine to be produced and used in front line aircraft of the Third Reich during World War II. The DB 603 powered several aircraft, including the Do 217 N&M, Do 335, He 219, Me 410, BV 155 and Ta 152C. Design and development The Mercedes-Benz T80 land speed record car, designed by aircraft engineer Josef Mickl with assistance from Ferdinand Porsche and top German Grand Prix racing driver Hans Stuck, incorporated the third prototype DB 603. It was set up for the land speed record run attempt to operate on an exotic fuel mix based on a 63% methanol, 16% benzene and 12% ethanol content, with minor percentages of acetone, ...

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] |
