Nakajima J5N
The Nakajima J5N was an abandoned Japanese prototype fighter aircraft of the World War II era. J5N was developed as twin-engine interceptor for countering attacks by Boeing B-29 Superfortress. Design and development During the spring of 1943, the JNAF issued an 18-Shi specification for a single-seat twin-engine interceptor capable of reaching a top speed of 666 km/h (414 mph) at 6,000 m (19,690 ft). Nakajima submitted a proposal based on the earlier J1N1 ''Gekko'' three-seat night fighter, although this new aircraft – designated J5N1 – was slightly smaller. The layout of the J5N was similar to the J1N: a low set wing on which were mounted the two powerplants, 1,484 kW (1,990 hp) Nakajima Homare 21 18-cylinder air-cooled radial engines, with a long fuselage ending in a conventional tail arrangement. For maximum utilization of the power from the twin engines, large four-blade propellers were fitted which also featured large spinners (as fitt ...

Nacelle
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engi ...

Mitsubishi Ki-83
The Mitsubishi Ki-83 (キ83) was a Japanese experimental long range heavy fighter designed near the end of World War II. It did not reach production status. Design and development The Mitsubishi Ki-83 was designed as a long range heavy fighter. It was designed and built by a team led by Tomio Kubo, designer of the highly successful Mitsubishi Ki-46. The design was a response to a 1943 specification for a new heavy fighter with great range. The first of four prototypes flew on 18 November 1944. The machines displayed remarkable maneuverability for aircraft of their size, being able to execute a 671 m (2,200 ft) diameter loop in just 31 seconds at a speed of over 644 km/h (400 mph). The Ki-83 carried a powerful armament of two 30 mm (1.18 in) and two 20 mm cannon in its nose. Despite the bomb-ravaged Japanese manufacturing sector, plans for the Ki-83 to enter production were underway when Japan surrendered on 15 August 1945. Both the existence an ...

Kawasaki Ki-96
The Kawasaki Ki-96 was a Japanese single seat, twin-engine heavy fighter of World War II. It was intended to replace the Kawasaki Ki-45s of the Imperial Japanese Army Air Service. However, it was not adopted and only three prototypes were built. Design and development The success of the Kawasaki Ki-45 led Kawasaki to start development of an evolved version, on Kawasaki's own authority, in August 1942. Like the Ki-45, the proposed design was a two-seat, twin-engine fighter, but larger and using more powerful engines. In December 1942 the ''Koku Hombu'' ( Imperial Japanese Army Aviation Bureau) showed interest, but asked Kawasaki to complete the aircraft as single-seat fighters. The first prototype, which was converted while being produced and which retained the larger cockpit canopy Canopy may refer to: Plants * Canopy (biology), aboveground portion of plant community or crop (including forests) * Canopy (grape), aboveground portion of grapes Religion and ceremonies * Balda ...

Grumman F7F Tigercat
The Grumman F7F Tigercat is a heavy fighter aircraft that served with the United States Navy (USN) and United States Marine Corps (USMC) from late in World War II until 1954. It was the first twin-engine fighter to be deployed by the USN. While the Tigercat was delivered too late to see combat in World War II, it saw action as a night fighter and attack aircraft during the Korean War. Designed initially for service on ''Midway''-class aircraft carriers, early production F7Fs were land-based variants. The type was too large to operate from older and smaller carriers, and only a late variant (F7F-4N) was certified for carrier service. Design & development Based on the earlier Grumman XP-50 that was eventually canceled, the company developed the XP-65 (Model 51) further for a future "convoy fighter" concept. In 1943, work on the XP-65 was terminated in favor of the design that would eventually become the F7F.Dorr and Donald 1990, p. 119. The contract for the prototype XF7F-1 wa ...

De Havilland Hornet
The de Havilland DH.103 Hornet, developed by de Havilland, was a fighter aircraft driven by two piston engines. It further exploited the wooden construction techniques that had been pioneered by the de Havilland Mosquito. Development of the Hornet had started during the Second World War as a private venture. The aircraft was to conduct long range fighter operations in the Pacific Theatre against the Empire of Japan but the war ended before the Hornet reached operational squadron status. The Hornet entered service with RAF Fighter Command where it equipped several day fighter units and was commonly stationed in the British mainland. It saw combat in the Far East, being used as a strike fighter as part of the British military action taken during the Malayan Emergency. A naval carrier-capable version, the Sea Hornet, had been envisaged early on and was procured by the Fleet Air Arm of the Royal Navy. Development Origins In the autumn of 1941, de Havilland found that it had the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 99 Cannon
The Type 99 Mark 1 machine gun and Type 99 Mark 2 machine gun were Japanese versions of the Oerlikon FF and Oerlikon FFL autocannons respectively. They were adopted by the Imperial Japanese Navy (IJN) in 1939 and served as their standard aircraft autocannon during World War II. Adoption In 1935, officers in the Imperial Japanese Navy began to investigate 20 mm automatic cannon as armament for future fighter aircraft.Robert C. Mikesh, ''Zero'', Motorbooks USA, 1994. Their attention was drawn to the family of aircraft autocannon manufactured by Oerlikon, the FF, FFL and FFS. These all shared the same operating principle, the advanced primer ignition blowback mechanism pioneered by the Becker cannon, but fired different ammunition: 20×72RB, 20×101RB, and 20×110RB, respectively. Following the import and evaluation of sample guns, the Imperial Japanese Navy decided in 1937 to adopt these weapons. To produce the Oerlikon guns, a group of retired Navy admirals created a new ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
20 Mm Caliber
20 mm caliber is a specific size of popular autocannon ammunition. It is typically used to distinguish smaller-caliber weapons, commonly called "guns", from larger-caliber "cannons" (e.g. machine gun vs. autocannon). All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of . These projectiles are typically long, cartridge cases are typically long, and most are shells, with an explosive payload and detonating fuze. Weapons using this caliber range from anti-materiel rifles and anti-tank rifles to aircraft autocannons and anti-aircraft guns. Usage Twenty-millimeter-caliber weapons are generally not used to target individual soldiers, but have targets such as vehicles, buildings, or aircraft. Types of ammunition *High explosive (HE) *High explosive incendiary (HEI) *Armor-piercing (AP) * Semi-armor-piercing high explosive incendiary (SAPHEI) *Armor-piercing discarding sabot (APDS) *High explosive fragmentation tracer (HEF-T) * High ex ...

Type 5 Cannon
The 30 mm Type 5 cannon was a Japanese Navy autocannon used near the end of World War II. It was an indigenous 30 mm design with better performance than the Navy's earlier Oerlikon-derived Type 2 or the Imperial Army's Browning-derived Ho-155, although it was considerably heavier. The Type 5 was to have become the standard fighter cannon of the Japanese Navy – four would have been mounted on the J7W Shinden – but by the end of the war had seen use on only a few aircraft, including variants of the Mitsubishi J2M and Yokosuka P1Y. Specifications *Caliber: 30 mm (1.2 in) *Ammunition: 30 × 122 (345 g) *Weight: 70 kg (155 lb) *Rate of fire: 350 rounds/min Cannon was constructed by engineer Masaya Kawamura, in Nihon Tokushu-Ko KK, and produced in Navy factories in Toyokawa and also in small numbers KK Nihon Seikojo and Nihon Tokushu-Ko KK.

30 Mm Caliber
30 mm caliber is a specific size of popular autocannon ammunition. Such ammunition includes NATO standard 30×113mmB and 30×173mm (STANAG 4624), Soviet 30×155mmB, 30×165mm, and 30×210mmB, Yugoslav 30×192mm, Anglo-Swiss 30×170mm, and Czechoslovak 30×210mm rounds which are widely used around the world. Usage Thirty-millimeter ammunition is typically not used against personnel, but rather as an anti-materiel or armor-piercing round. Rounds of this size can be effective against lightly armored vehicles as well as fortified bunkers. It is also a popular caliber for shipboard close-in weapons systems, such as the Russian AK-630 and Dutch Goalkeeper CIWS. The Armed Forces of the Russian Federation use their 30 mm weapons in a variety of vehicles, including the Su-25 attack aircraft, Mi-24 helicopter, Mi-28 attack helicopter, Ka-50 attack helicopter, and the BMP-2, BMP-3, and BTR-90 infantry fighting vehicles.
