Focke-Wulf Ta 152
The Focke-Wulf Ta 152 is a German high-altitude fighter and interceptor aircraft designed by Kurt Tank and produced by Focke-Wulf. It entered production too late and in insufficient numbers to have a significant role in the Second World War. The Ta 152 was developed from the Focke-Wulf Fw 190 fighter. It was intended to be produced in at least three versions—the Ta 152H (high-altitude fighter); the Ta 152C designed for medium-altitude operations and ground-attack, using a Daimler-Benz DB 603 and with smaller wings and the Ta 152E fighter– reconnaissance aircraft with the engine of the H model and the wing of the C model. The first Ta 152H entered service with the ''Luftwaffe'' in January 1945; one month later production of the Ta 152 had ceased due to Germany's declining position in the conflict. Japan acquired material from Germany towards establishing domestic production of the Ta 152, but no aircraft are believed to have been completed. Development Fw 190 The Fw 190 ...

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-b ...

Heavy Bomber
Heavy bombers are bomber Fixed-wing aircraft, aircraft capable of delivering the largest payload of air-to-ground weaponry (usually Aerial bomb, bombs) and longest range (aeronautics), range (takeoff to landing) of their era. Archetypal heavy bombers have therefore usually been among the largest and most powerful Military aviation, military aircraft at any point in time. In the second half of the 20th century, heavy bombers were largely superseded by strategic bombers, which were often even larger in size, had much longer ranges and were capable of delivering nuclear bombs. Because of advances in Aerospace engineering, aircraft design and engineering — especially in Aircraft engine, powerplants and aerodynamics — the size of payloads carried by heavy bombers has increased at rates greater than increases in the size of their airframes. The largest bombers of World War I, the ''Riesenflugzeuge'' of Germany, could carry a payload of up to of bombs; by the latter half of World ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, Potsdam Declaration, when it was dissolved following surrender of Japan, Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952 and 1954 after the dissolution of the IJN. The IJN was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for reconnaissance and airstrike operations from the fleet. It was the primary opponent of the Allies of World War II, Western Allies in the Pacific War. The IJN additionally fielded Imperial Japanese Navy land forces, limited land-based forces, including Special Naval Landing Forces, professional marines, Japanese marine paratroopers of World War II, marine paratrooper units, anti-aircraft defense units ...

Imperial Japanese Army
The Imperial Japanese Army (IJA; , ''Dai-Nippon Teikoku Rikugun'', "Army of the Greater Japanese Empire") was the principal ground force of the Empire of Japan from 1871 to 1945. It played a central role in Japan’s rapid modernization during the Meiji period, fought in numerous conflicts including the First Sino-Japanese War, the Russo-Japanese War, World War I, the Second Sino-Japanese War, and World War II, and became a dominant force in Japanese politics. Initially formed from domain armies after the Meiji Restoration, it evolved into a powerful modern military influenced by French and German models. The IJA was responsible for several overseas military campaigns, including the invasion of Manchuria, involvement in the Boxer Rebellion, and fighting across the Asia-Pacific during the Pacific War. Notorious for committing widespread Japanese war crimes, war crimes, the army was dissolved after Japan's surrender in 1945, and its functions were succeeded by the Japan Ground Self-D ...

Licenced Production
Licensed production is the production under license of technology developed elsewhere. The licensee provides the licensor of a specific product with legal production rights, technical information, process technology, and any other proprietary components that cannot be sourced by the licensor. This is an especially prominent commercial practice in developing nations, which often approach licensed production as a starting point for indigenous industrial development. While licensed production in developing nations provides stimulus to the production and technical capabilities of local industry, in many cases it remains at least partly dependent on foreign support. History The four most common applications of licensed production have historically been automotive engines and parts, weaponry, aircraft, and pharmaceuticals. During World War I, it was more common for licensing agreements to take place between companies in the same country; for example, Opel was granted a license to pr ...

Imperial Japanese Army Air Service
The Imperial Japanese Army Air Service (IJAAS) or Imperial Japanese Army Air Force (IJAAF; ) was the Military aviation, aviation force of the Imperial Japanese Army (IJA). Its primary mission was to provide tactical close air support for ground forces, as well as a limited air interdiction capability. The IJAAS also provided aerial reconnaissance to other branches of the IJA. While the IJAAS engaged in Strategic bombing during World War II, strategic bombing of cities such as Shanghai, Battle of Nanking#Aerial bombardment of Nanking, Nanjing, Guangzhou, Canton, Bombing of Chongqing, Chongqing, Bombing of Rangoon in World War II, Rangoon, and Bombing of Mandalay (1942), Mandalay, this was not the primary mission of the IJAAS, and it lacked a heavy bomber force. It did not usually control artillery spotter/observer aircraft; artillery battalions controlled the light aircraft and observation balloon, balloons that operated in these roles. The Imperial Japanese Navy Air Service was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation prototypical. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms ...

Ground-attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se''; fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bf 109H
Due to the Messerschmitt Bf 109's versatility and time in service with the German and foreign air forces, numerous variants were produced in Germany to serve for over eight years with the Luftwaffe. Additional variants were produced abroad totalling in 34,852 Bf 109s built. Bf 109 A/B/C/D The Bf 109A was the first version of the Bf 109. Armament was initially planned to be just two cowl-mounted 7.92 mm (.312 in) MG 17 machine guns. However, possibly due to the introduction of the Hurricane and Spitfire, each with eight 7.7 mm (.303 in) machine guns, experiments were carried out with a third machine gun firing through the propeller shaft. V4 and some A-0 were powered by a 640 PS (631 hp, 471 kW) Junkers Jumo 210B engine driving a two-blade fixed- pitch propeller, but production was changed to the 670 PS (661 hp, 493 kW) Jumo 210D as soon as it became available. The A-0 was not of a uniform type; there were several changes in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichsluftfahrtministerium
The Ministry of Aviation (, abbreviated RLM) was a government department during the period of Nazi Germany (1933–45). It is also the original name of the Detlev-Rohwedder-Haus building on the Wilhelmstrasse in central Berlin, Germany, which houses the modern German Finance Ministry (). The Ministry was in charge of development and production of all aircraft developed, designed, and built in Germany during the existence of the Third Reich, overseeing all matters concerning both military and civilian designs – it handled military aviation matters as its top priority, particularly for the Luftwaffe. As was characteristic of government departments in the Nazi era, the Ministry was personality-driven and formal procedures were often ignored in favour of the whims of the Minister, ''Reichsmarschall'' Hermann Göring. As a result, early successes in aircraft development progressed only slowly and erratically during World War II. History The Ministry was formed on 27 April 1933 ...

Boeing B-29 Superfortress
The Boeing B-29 Superfortress is a retired American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the Boeing B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 and a half dollar cost of design and production (equivalent to $6769 billion in 400), fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
