Mitsubishi A7M
The Mitsubishi A7M ''Reppū'' (烈風, "Strong Wind") was designed as the successor to the Imperial Japanese Navy's A6M Zero, with development beginning in 1942. Performance objectives were to achieve superior speed, climb, diving, and armament over the Zero, as well as better maneuverability. To meet these performance specifications its size and weight were significantly greater than its predecessor. The A7M's allied codename was "Sam". Design and development Towards the end of 1940, the Imperial Japanese Navy asked Mitsubishi to start design on a carrier-based fighter, to meet specification ''16-Shi'' (a designation under a system using regnal years that indicated "1941" – the year in which the specification was formally issued). The fighter would be the successor to the carrier-based Zero. At that time, however, there were no viable high-output, compact engines to use for a new fighter. In addition, Jiro Horikoshi's team was preoccupied with addressing early production issue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mitsubishi Kinsei
The was a 14-cylinder, air-cooled, twin-row radial aircraft engine developed by Mitsubishi Heavy Industries in Japan in 1934 for the Imperial Japanese Navy. The Mitsubishi model designation for this engine was A8 while it was an experimental project; in service, it was known as the MK8 "Kinsei" by the Navy. In 1941 the engine was adopted by Army, receiving designation Ha-112 (later Ha-112-I, 1,300hp Army Type 1). In May 1943 it received Ha-33 unified designation code. Design and development Early Kinsei models (1 and 2) had A4 internal designation and their cylinder and detail design was based on the single-row, 9-cylinder air-cooled Pratt and Whitney R-1690 Hornet. In 1933 engine underwent a major redesign and redesignated A8. Head layout was reversed to allow exhaust exit to the rear, reducing back-pressure and allowing for a cleaner installation. Compression ratio increased from 5.3:1 to 6.0:1. These changes resulted in a significant performance uplift, compared to pre ...

Mitsubishi MK9C
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 ...

Bombing Of Nagoya In World War II
The Bombing of Nagoya in World War II by the United States Army Air Forces took place as part of the air raids on Japan during the closing months of the war. History The first strategic bombing attack on Nagoya was on April 18, 1942, as part of the Doolittle Raid. A B-25 bomber targeted the Mitsubishi Aircraft Works, the Matsuhigecho oil warehouse, the Nagoya Castle military barracks, and the Nagoya war industries plant. However, it was not until the aerial attacks of 1944 and 1945 that Nagoya would suffer serious bomb damage. According to the United States Strategic Bombing Survey, during the last 9 months of the Pacific War 14,054 tons of bombs were dropped in precision and area air attacks on the factories and urban areas of Nagoya. No other Japanese city other than Tokyo received as many attacks. The city was attacked 21 times between December 13, 1944 and July 24, 1945. The aim of the attacks was stated as ''"(1) mainly by precision attacks, to wipe out Nagoya's aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nagoya
is the largest city in the Chūbu region, the fourth-most populous city and third most populous urban area in Japan, with a population of 2.3million in 2020. Located on the Pacific coast in central Honshu, it is the capital and the most populous city of Aichi Prefecture, and is one of Japan's major ports along with those of Tokyo, Osaka, Kobe, Yokohama, and Chiba. It is the principal city of the Chūkyō metropolitan area, which is the third-most populous metropolitan area in Japan with a population of 10.11million in 2020. In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. The arrival of the 20th century brought a convergence of economic factors that fueled rapid growth in Nagoya, during the Meiji Restoration, and became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1944 Tōnankai Earthquake
The 1944 Tōnankai earthquake occurred at 13:35 local time (04:35 UTC) on 7 December. It had an estimated magnitude of 8.1 on the moment magnitude scale (making it the strongest known earthquake of 1944) and a maximum felt intensity of greater than 5 Shindo (about VIII (''Severe'') on the Mercalli intensity scale). It triggered a large tsunami that caused serious damage along the coast of Wakayama Prefecture and the Tōkai region. Together, the earthquake and tsunami caused 3,358 casualties. Tectonic setting The southern coast of Honshū runs parallel to the Nankai Trough, which marks the subduction of the Philippine Sea Plate beneath the Eurasian Plate. Movement on this convergent plate boundary leads to many earthquakes, some of them of megathrust type. The Nankai megathrust has five distinct segments (A–E) that can rupture independently, the segments have ruptured either singly or together repeatedly over the last 1300 years. Megathrust earthquakes on this structure tend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
Type 3 Aircraft Machine Gun
Type 3 (三式, San-Shiki) was a Japanese Navy aircraft machine gun used during World War II. It was based on the American M2 Browning machine gun but used the 13.2x99mm Hotchkiss cartridge. History The Type 3 was a copy of the M2 Browning and had very similar ammunition to that of the 13.2 mm Hotchkiss M1929 machine gun. Despite the small difference in calibers, it was possible to use M2 Browning tapes in the Japanese machine gun, which apparently took place during World War II. The machine gun was produced from 1943 to 1945. It came in flexible and fixed versions which differed slightly in construction details. The flexible version featured a longer barrel. The fixed version was used on later models of the Mitsubishi A6M Zero fighterRené J. Francillon: Japanese Aircraft of the Pacific War. s. 531. and prototypes of the Kawanishi N1K Shiden Kai.A. G.

Saburō Sakai
was a Japanese naval aviator and flying ace (''"Gekitsui-O"'', ) of the Imperial Japanese Navy during World War II. Sakai had 28–64 aerial victories, including shared ones, according to official Japanese records, but his autobiography, ''Samurai!'', which was co-written by Martin Caidin and Fred Saito, claims 64 aerial victories. Early life Saburō Sakai was born on 25 August 1916 in Saga Prefecture, Japan. He was born into a family with an immediate affiliation to the samurai and their warrior legacies. Their ancestors were themselves samurai and had taken part in the Japanese invasions of Korea (1592–1598) but were later forced to take up a livelihood of farming after '' haihan-chiken'' in 1871. He was the third-born of four sons (his given name literally means "third son") and had three sisters. Sakai was 11 when his father died, which left his mother alone to raise seven children. With limited resources, Sakai was adopted by his maternal uncle, who financed his education i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawanishi N1K-J
The Kawanishi N1K ''Kyōfū'' (, "Strong Wind", Allied reporting name "Rex") is an Imperial Japanese Navy floatplane fighter. The Kawanishi N1K-J ''Shiden'' (, "Violet Lightning") was an Imperial Japanese Navy Air Service land-based version of the N1K. Assigned the reporting name "George", the N1K-J was considered by both its pilots and opponents to be one of the finest land-based fighters flown by the Japanese during World War II. The ''Shiden Kai'' possessed heavy armament, as well as surprisingly good maneuverability, due to a mercury switch that automatically extended the flaps during turns. These "combat" flaps created more lift, thereby allowing tighter turns. Unlike the Mitsubishi A6M Zero, the ''Shiden Kai'' could compete against the best late-war Allied fighters, such as the F6F Hellcat, F4U Corsair, and P-51 Mustang. Design and development Kawanishi's N1K was originally built as a single pontoon floatplane fighter to support forward offensive operations where no air ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...
