B7A Ryusei
The was a large and powerful carrier-borne torpedo-dive bomber produced by Aichi Kokuki for the Imperial Japanese Navy Air Service during the Second World War. Built in only small numbers and deprived of the aircraft carriers it was intended to operate from, the type had little chance to distinguish itself in combat before the war ended in August 1945. Design and development The B7A ''Ryusei'' (originally designated AM-23 by Aichi)Francillon 1979, p. 289. was designed in response to a 1941 16-Shi requirement issued by the Imperial Japanese Navy Air Service for a carrier attack bomber that would replace both the Nakajima B6N ''Tenzan'' torpedo plane and the Yokosuka D4Y ''Suisei'' dive bomber in IJN service. It was intended for use aboard a new generation of ''Taihō''-class carriers, the first of which was laid down in July 1941. Because the deck elevators on the ''Taihō''s had a larger square area than those of older Japanese carriers, the longstanding maximum limit of on ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...

Kōkūtai
A ''Kōkūtai'' () was a term used by the Imperial Japanese Navy Air Service (IJNAS) to designate a military aviation unit, similar to the Air Groups in other air arms and services of the time. (''Group'' in the British Royal Air Force, ''Gruppe'' in the German Luftwaffe, ''Groupe'' in the French Armée de l'Air etc.) A Kōkūtai could be based at land or on board aircraft carriers and could contain up to hundreds of men and aircraft. For example, the famous 343 Kōkūtai was a land based fighter group while the 652nd Kōkūtai was a carrier-based bomber group. Kōkūtai were divided into smaller units called Hikōtai, which were the equivalent of a squadron. Kōkūtai were usually divided into three Hikōtai. In general, most pilots and aircrew in the Imperial Japanese Navy Air Service were non-commissioned officers. The word Kōkūtai is abbreviated with the abbreviation "Ku" (空). 343 Ku, for example, stands for 343 Kōkūtai. In the Imperial Japanese Army Air Service (IJAA ...

Battle Of The Philippine Sea
The Battle of the Philippine Sea (June 19–20, 1944) was a major naval battle of World War II that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. This was the largest carrier-to-carrier battle in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft. The aerial part of the battle was nicknamed the Great Marianas Turkey Shoot by American aviators for the severely disproportional loss ratio inflicted upon Japanese aircraft by American pilots and anti-aircraft gunners. During a debriefing after the first two air battles, a pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Aircraft Carrier Taihō
was an aircraft carrier of the Imperial Japanese Navy during World War II. Possessing heavy belt armor and featuring an armored flight deck (a first for any Japanese aircraft carrier), she represented a major departure from prior Japanese aircraft carrier design and was expected to not only survive multiple bomb, torpedo, or shell hits, but also continue fighting effectively afterwards. Built by Kawasaki at Kobe, she was laid down on 10 July 1941, launched almost two years later on 7 April 1943 and finally commissioned on 7 March 1944. She sank on 19 June 1944 during the Battle of the Philippine Sea due to explosions resulting from design flaws and poor damage control after suffering a single torpedo hit from the American submarine USS ''Albacore''. Design ''Taihō'' was approved for construction in the 1939 4th Supplementary Programme. Her design was that of a modified . Under the Modified Fleet Replenishment Program of 1942, ''Taihō'' was to be the first of a new generat ... [...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. 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 such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...

Mitsubishi A6M Zero
The Mitsubishi A6M "Zero" is a long-range carrier-based aircraft, carrier-based fighter aircraft formerly manufactured by Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and was operated by the Imperial Japanese Navy from 1940 to 1945. The A6M was designated as the , or the Mitsubishi A6M Rei-sen. The A6M was usually referred to by its pilots as the ''Reisen'' (, zero fighter), "0" being the last digit of the Japanese calendar#Years, imperial year 2600 (1940) when it entered service with the Imperial Navy. The official World War II Allied names for Japanese aircraft, Allied reporting name was "Zeke", although the name "Zero" (from Type 0) was used colloquially as well. The Zero is considered to have been the most capable carrier-based aircraft, carrier-based fighter in the world when it was introduced early in World War II, combining excellent maneuverability and very long range.Hawks, Chuck"The Best Fighter Planes of World War II" chuckhawks.com.

Type 93 Torpedo
The was a -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given to it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time. History and development The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the s. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet.

Type 91 Torpedo
The Type 91 was an aerial torpedo of the Imperial Japanese Navy. It was in service from 1931 to 1945. It was used in naval battles in World War II and was specially developed for attacks on ships in shallow harbours. The Type 91 aerial torpedo had two unique characteristics. Firstly, it used wooden stabilizers attached to the tail fins which were shed upon water entry. Secondly, it engaged an angular acceleration control system to control rolling movements, which was very advanced for its time. This system made it possible to release the Type 91 not only at a cruising speed of at an altitude of , but also in a power-glide torpedo-bombing run at the maximum speed of the Nakajima B5N or ''Kate'', The Type 91 torpedo was in diameter. There were five models put into service, with high-explosive warheads weighing and having effective ranges of at . Since the Type 91 torpedo was the only practical aerial torpedo of the Imperial Japanese Navy, it was simply known as the ''Ko ...

Bomb
A bomb is an explosive weapon that uses the Exothermic process, exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress (mechanics), stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term bomb is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shell (projectile), shells, depth charges (used in water), or lan ...

Mitsubishi Ha-43
The Mitsubishi Ha-43, known as the Ha-211 by the Imperial Japanese Army Air Force (IJAAF) and MK9 by the Imperial Japanese Navy Air Service (IJNAS)), was a Japanese 18-cylinder, twin-row air-cooled radial engine developed during World War II. It was a more powerful derivative of Mitsubishi's 14-cylinder Kinsei. While planned for use in several promising aircraft, only prototypes were made and the engine never saw combat. Design and development The Ha-43 was Mitsubishi's answer to Nakajima's Ha-45. The engine was planned to produce while retaining high reliability and a superior power-to-weight ratio compared to contemporary engines in its class. The frontal area per hp. was also intended to be the smallest in the world. However, such ambitious targets necessitated extraordinary efforts and ingenuity at the same time. At the time, Mitsubishi was working to promote a different engine, the Ha-42 (an 18-cylinder derivative of the Kasei), development of which was priorit ...
