Yokosuka B3Y
The Kugisho B3Y, or Navy Type 92 Carrier Attack Bomber, also popularly titled Yokosuka B3Y, was a Japanese carrier-based torpedo bomber of the 1930s. It was designed by the Naval Air Technical Arsenal at Yokosuka, and while unimpressive during testing, it was ordered into service by the Imperial Japanese Navy and used until replaced by more capable aircraft. Development and design In 1932, the Imperial Japanese Navy had a requirement, 7-''Shi'', for a new torpedo bomber to replace the Mitsubishi B2M. The air arsenal at Yokosuka prepared its own design to meet this requirement, competing against designs by Mitsubishi and Nakajima. The resulting aircraft was a three-seat single-engine biplane, with a fuselage of steel tube construction and two-bay wooden wings that could fold rearwards for storage aboard aircraft carriers. It was powered by a single Hiro Type 91 W engine rated at 450 kW (600 hp). Testing proved that the aircraft had poor stability and control, and ...

W Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons. W6 engines The Rumpler Tropfenwagen had a Siemens and Halske-built overhead valve W6 engine, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin BM
The Martin BM was a 1930s American torpedo bomber built by the Glenn L. Martin Company for the United States Navy. Design and development To meet the requirement for a special-purpose dive bomber for the United States Navy and United States Marine Corps, the US Navy's Bureau of Aeronautics designed a biplane with fixed tailwheel landing gear, designated Bureau Design 77. It had room for two crew in tandem. Two prototypes were ordered in June 1928, one from Martin (designated the XT5M-1) and one from the Naval Aircraft Factory (designated the XT2N-1). The Martin XT5M-1 was powered by a Pratt & Whitney R-1690-22 Hornet radial engine, and, following test during 1930, the Navy ordered 12 aircraft from Martin with the designation BM-1. The BM-1 had a more powerful R-1690-44 engine. A further order for four was followed by an order for 16 for the BM-2. Martin moved to a new factory in Baltimore, Maryland, where the XT5M-1 was built, and it was first flown on 17 May 1929. During test ...

Fairey Swordfish
The Fairey Swordfish is a biplane torpedo bomber, designed by the Fairey Aviation Company. Originating in the early 1930s, the Swordfish, nicknamed "Stringbag", was principally operated by the Fleet Air Arm of the Royal Navy. It was also used by the Royal Air Force (RAF), as well as several overseas operators, including the Royal Canadian Air Force (RCAF) and the Royal Netherlands Navy. It was initially operated primarily as a fleet attack aircraft. During its later years, the Swordfish was increasingly used as an anti-submarine and training platform. The type was in frontline service throughout the Second World War. Despite being outmoded by 1939, the Swordfish achieved some spectacular successes during the war. Notable events included sinking one battleship and damaging two others of the ''Regia Marina'' (the Italian navy) during the Battle of Taranto, and the famous attack on the German battleship ''Bismarck'', which contributed to her eventual demise. Swordfish sank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn Shark
The Blackburn Shark was a carrier-borne torpedo bomber designed and built by the British aviation manufacturer Blackburn Aircraft. It was originally known as the Blackburn T.S.R., standing for ''torpedo-spotter-reconnaissance'', in reference to its intended roles. The Shark was the last of Blackburn's biplane torpedo bombers. The prototype Shark performed its maiden flight on 24 August 1933, the first production aircraft was introduced to service during the following year. It was operated by the Fleet Air Arm, Royal Canadian Air Force, Portuguese Navy, and the British Air Observers' School. By 1937, the Shark was already approaching obsolescent and replacement by the more capable Fairey Swordfish began during the following year. Despite this, numerous aircraft continued to be operated during the Second World War, largely being confined to secondary roles away from the front lines, such as training and target tug duties. Despite this, Sharks were repeatedly deployed in front ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiro Type 91 520 Hp Water-cooled W-12
The Hiro Type 91, (full designation Hiro Type 91 520 hp water-cooled W-12), was a 12-cylinder, water-cooled, W engine developed for aircraft use by the Imperial Japanese Navy in the mid-1930s. Power was in the 450 kW (600 hp) range. Its design was derived from the Napier Lion. An enlarged more powerful engine, the Hiro Type 90 600 hp water-cooled W-12 had also been developed, producing 600 hp.

Yokosuka B4Y
The Yokosuka B4Y, (Navy Type 96 Carrier Attack Bomber), carrier-borne torpedo bomber was used by the Imperial Japanese Navy Air Service from 1936 to 1943. The B4Y replaced the Mitsubishi B2M2 and was the last biplane bomber used operationally by the Imperial Japanese Navy. The Allied reporting name was "Jean". Design and development In 1932, the Imperial Japanese Navy issued a requirement for a new carrier-borne attack aircraft. Aichi, Mitsubishi and Nakajima responded to this requirement and each built a prototype. None of these aircraft were deemed satisfactory, and the service thus issued in 1934 a new requirement, 9-''Shi'', for a more capable aircraft to replace the obsolescent Yokosuka B3Y. The B4Y was designed by Sanae Kawasaki at the First Naval Air Technical Arsenal at Yokosuka. Regarded only as an interim type, the Navy wanted a torpedo bomber offering performance comparable to the Mitsubishi A5M monoplane fighter. The result was a biplane with fixed landing g ...

Dive Bomber
A dive bomber is a bomber aircraft that Dive (aviation), dives directly at its targets in order to provide greater accuracy for the Aerial bomb, bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved Anti-aircraft warfare, anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighter aircraft, fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aichi D1A
The Aichi D1A or Navy Type 94/96 Carrier Bomber ( Allied reporting name "Susie") was a Japanese carrier-based dive bomber of the 1930s. A single-engine, two-seat biplane based on the Heinkel He 50, the D1A was produced by Aichi for the Imperial Japanese Navy, remaining in service as a trainer at the time of the attack on Pearl Harbor. The D1A was produced in two variants, the D1A1 (Navy Type 94 Carrier Bomber), and the D1A2 (Navy Type 96 Carrier Bomber, sometimes referred to as the D2A). Design and development The D1A came out of the Imperial Japanese Navy's need for an advanced carrier-based dive bomber, and in late 1934 the IJN ordered the finalisation of the Aichi AB-9 design which was produced as the early model D1A1. However, the D1A1 was not designed by aircraft company (later Aichi Kokuki), but by Ernst Heinkel Flugzeugwerke at the request of the Aichi company. The initial version designed by Heinkel was the He 50, a similar model equipped with floats instead of landi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Sino-Japanese War
The Second Sino-Japanese War (1937–1945) or War of Resistance (Chinese term) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan. The war made up the Chinese theater of the wider Pacific Theater of the Second World War. The beginning of the war is conventionally dated to the Marco Polo Bridge Incident on 7 July 1937, when a dispute between Japanese and Chinese troops in Peking escalated into a full-scale invasion. Some Chinese historians believe that the Japanese invasion of Manchuria on 18 September 1931 marks the start of the war. This full-scale war between the Chinese and the Empire of Japan is often regarded as the beginning of World War II in Asia. China fought Japan with aid from Nazi Germany, the Soviet Union, United Kingdom and the United States. After the Japanese attacks on Malaya and Pearl Harbor in 1941, the war merged with other conflicts which are generally categorized under those conflicts of World War II ...
