Focke Wulf Ta 400
The Focke-Wulf Ta 400 was a large six-engined heavy bomber design developed in Nazi Germany in 1943 by Focke-Wulf as a serious contender for the Amerikabomber project. One of the first aircraft to be developed from components from multiple countries, it was also one of the most advanced Focke-Wulf designs of World War II, though it never progressed beyond a wind tunnel model. Designed as a bomber and long-range reconnaissance plane by Kurt Tank, the Ta 400 had a shoulder-mounted wing with 4° dihedral. One of the most striking features were the six BMW 801D radial engines, to which two Jumo 004 jet engines were later added. Design and development In response to the RLM guidelines of 22 January 1942, Kurt Tank of the Focke-Wulf company designed the Ta 400 as a bomber and long-range reconnaissance aircraft, to be powered by six BMW 801D radial engines, to which two Jumo 004 jet engines were later added. Design work was begun in 1943, much of it being carried out by French techni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-range Bomber
A strategic bomber is a medium- to long-range penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombers, penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after strategic bombing was widely employed, and atomic bombs were first used in combat during World War II. Nuclear strike missions (i.e., delivering nuclear-armed missiles or bombs) can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW 801D
The BMW 801 was a powerful German air-cooled 14-cylinder-radial aircraft engine built by BMW and used in a number of German Luftwaffe The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabtei ... aircraft of World War II. Production versions of the Radial engine#Multi-row radials, twin-row engine generated between 1,560 and 2,000 metric horsepower, PS (1,540–1,970 hp, or 1,150–1,470 Kilowatt, kW). It was the most produced radial engine of Germany in World War II with more than 61,000 built. The 801 was originally intended to replace existing radial types in German transport and utility aircraft. At the time, it was widely agreed among European designers that an inline engine (aviation), inline engine was a requirement for high performance designs due to its smaller frontal area a ...

Messerschmitt Me 264
The Messerschmitt Me 264 was a long-range strategic bomber developed during World War II for the German ''Luftwaffe'' as its main strategic bomber. The design was later selected as Messerschmitt's competitor in the ''Reichsluftfahrtministerium''s (the German Air Ministry) ''Amerikabomber'' programme, for a strategic bomber capable of attacking New York City from bases in France or the Azores. Three prototypes were built but production was abandoned to allow Messerschmitt to concentrate on fighter production and the Junkers Ju 390 was selected in its place. Development continued as a maritime reconnaissance aircraft instead. Development The origin of the Me 264 design came from Messerschmitt's long-range reconnaissance aircraft project, the P.1061, of the late 1930s. A variant on the P.1061 was the P.1062 of which three prototypes were built, with only two "engines" to the P.1061's four, but they were, in fact, the more powerful Daimler-Benz DB 606 "power systems", each comprisi ...

Heinkel He 277
The Heinkel He 277 was a four-engine, long-range heavy bomber design, originating as a derivative of the Heinkel He 177, He 177, intended for production and use by the Nazi Germany, German Luftwaffe during World War II. The main difference was in its engines. The He 177 used two Daimler-Benz DB 606 "power system" engines, each of which consisted of two combined Daimler-Benz DB 601 engines, each DB 606 weighed 1.5 tons. The He 177A-3 and its successors used two DB 610 "power system" engines, each of which consisted of two combined Daimler-Benz DB 605 engines, each DB 610 weighed 1.5 tons. Due to problems with both the DB 606 and the DB 610, the He 277 was intended to use four Kraftei, unitized BMW 801E 14-cylinder radial engines, each mounted in an individual nacelle and each turning a three-blade, four-meter diameter propeller. The design was never produced and no prototype airframe was completed.Griehl & Dressel 1998, p. 203 The deteriorating condition of the German aviation indu ...

Gross Weight
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force. Yet others define it as the magnitude of the reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale. Thus, in a state of free fall, the weight would be zero. In this sense of weight, terrestrial objects can be weightless: ignoring air resistance, the famous apple falling from the tree, on its way to meet the ground near Isaac Newton, would be weightless. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Tanks
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine. Fuel tanks range in size and complexity from the small plastic tank of a butane lighter to the multi-chambered cryogenic Space Shuttle external tank. Uses Typically, a fuel tank must allow or provide the following: * Storage of fuel: the system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions. * Filling: the fuel tank must be filled in a secure way, without sparks. * Provide a method for determining level of fuel in tank, gauging (the remaining quantity of fuel in the tank must be measured or evaluated). * Venting (if over-pressure is not allowed, the fuel vapors must be managed through valves). * Feeding of the engine (through a p ...

Heinkel He 177
The Heinkel He 177 ''Greif'' (Griffin) was a long-range heavy bomber flown by the ''Luftwaffe'' during World War II. The introduction of the He 177 to combat operations was significantly delayed, by both problems with the development of its engines, and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the ''Luftwaffe'' during the war. The He 177 had a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the European theatre. Work on the design began in response to a 1936 requirement, known as Bomber A, issued by the RLM for a purely strategic bomber. Thus the He 177 was intended originally to be capable of a sustained bombing campaign against Soviet manufacturing capacity, deep inside Russia. In contrast to its heavy payload and very wide, planform, the specifications called for the design to have only two very powerful engines. To deliver the power ...

MG 131 Machine Gun
The MG 131 (shortened from German: ''Maschinengewehr'' 131, or "Machine gun 131") was a German 13 mm caliber machine gun developed in 1938 by Rheinmetall-Borsig and produced from 1940 to 1945. The MG 131 was designed for use at fixed, flexible or turreted, single or twin mountings in Luftwaffe aircraft during World War II. It was one of the smallest, if not the smallest among the heavy machine guns of that conflict, with a weight of 16.6 kilograms (37 lb,) less than 60% of the M2 Browning or the Breda-SAFAT machine gun. Despite this, the MG 131 was a rapid fire weapon with an elevated firepower for its mass. It was equipped with HEI ammunition. Its nearest contemporary equivalent may have been the Japanese Ho-103, itself based on the earlier American M1921 Browning machine gun. The other main Axis automatic weapon of similar caliber, the Italian Breda 12.7 mm was around 13 kg heavier and bigger, while slower by at least 150 rpm. This small size allowed them to be mount ...

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 ...
