Nakajima Ki-201
The was a Japanese jet fighter-attacker project designed during the final stages of World War II but which was never completed. Development The Nakajima Kikka had been inspired by the successful German Messerschmitt Me 262, but the similarities to that aircraft were limited to the general configuration. On the other hand, the design team led by Iwao Shibuya based the ''Karyū'' far more closely on the German aircraft, which had already proven itself quite formidable. The Ki-201 project was ordered by the Imperial Japanese Army between October and December 1944, with the Army laying out a performance requirement of an 800~1,000 km/h top speed, 12,000 meter practical ceiling, and 800~1,000 km range. The design was advanced by Nakajima during 1945 and the basic drawings were completed in June. Nakajima anticipated the completion of the first ''Karyū'' by December 1945, and the first 18 units by March 1946. Most sources agree that work on the first prototype A ...

Jet Airplane
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered flig ...

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] |

1940s Japanese Fighter Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

List Of Jet Aircraft Of World War II
World War II was the first war in which jet aircraft participated in combat with examples being used on both sides of the conflict during the latter stages of the war. The first successful jet aircraft, the Heinkel He 178, flew only five days before the 1 September 1939 start of the war. By the end of the conflict on 2 September 1945 Germany, the United Kingdom, and the United States all had operational turbojet-powered fighter aircraft while Japan had produced, but not used, motorjet-powered kamikaze aircraft, and had tested and ordered into production conventional jets. Italy and the Soviet Union had both tested motorjet aircraft which had turbines powered by piston engines and the latter had also equipped several types of conventional piston-powered fighter aircraft with auxiliary ramjet engines for testing purposes. Germany was the only country to use jet-powered bombers operationally during the war. This list includes only aircraft powered by turbine engines, either on their o ...

Ho-5 Cannon
The Ho-5 (Army Type 2) was a Japanese aircraft autocannon used during World War II. Developed from the Ho-103 machine gun, it was a version of the American Model 1921 Browning aircraft machine gun. It replaced the Ho-1 and Ho-3 (Army Type 97) in general service. The Ho-5 was belt-fed using typical Browning-style steel disintegrating links. The cartridge used was a shortened version of the Allied 20 x 110mm Hispano-Suiza HS.404. The Ho-5 was used mostly as wing mounts in late-war fighters, but saw limited use as cowl mounted in fighters and as flexible mounted (retrofit) in bombers.

Ho-155 Cannon
The 30 mm Ho-155 cannon was a Japanese aircraft autocannon used during World War II, often mistakenly called with the Ho-105 or Ho-151. A lighter and more compact Ho-155-II was designed towards the end of the war. Development The Ho-155-I was first began development in 1942 as a scaled-up and modified version of the 20mm Ho-5 cannon, itself a scaled-up Model 1921 aircraft .50-inch Browning machine gun. In 1943-44 began development of the Ho-155-I and in late 1944 began the development and production of the Ho-155-II for fit into tighter wing bays of fighter planes such as the Ki-84-Ic, Ki-102 and on the project design of the jet-powered Ki-201.

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. 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 and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed ''Schwalbe'' (German: "Swallow") in fighter versions, or ''Sturmvogel'' (German: "Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft. The initial design of what would become the Me 262 started in April 1939, prior to the start of the Second World War. While the aircraft performed its maiden flight on 18 April 1941, this was using piston engine instead of jet propulsion; it was not until 18 July 1942 that the first jet-powered flight was performed. Progress on the project was delayed by problems with engines, metallurgy and top-level interference from figures such as Hermann Göring, head of the Luftwaffe, and Adolf Hitler. The latter advocated from the Me 262 to be operated as a ground-attack/bomber aircraft rather than a defensive interceptor, thus necessitating a ...
