Type 98 Ta-Se
The experimental Type 98 Ta-Se was a Japanese self-propelled anti-aircraft gun using a Type 98 20 mm anti-aircraft gun. It used the chassis of the Type 98 Ke-Ni light tank. It did not enter production. Development During development of the AA gun tank, the Imperial Japanese Army experimented with various configurations. This single gun prototype was designated the Type 98 Ta-Se self-propelled anti-aircraft gun. Initial development began in November 1941. The name was taken from ''taikū'' ('anti-air') ''sensha'' ('tank'). The conventional turret was removed from the hull and a new open-top cylindrical shaped turret was installed. It was equipped with a single converted Type 98 20 mm AA machine cannon. During trials, it was determined that the chassis used for the Ta-Se was too small to be a stable "firing platform". It did not enter production. Gallery File:Jap exp aa tank ta-se - front view.jpg, Front view of Type 98 Ta-Se File:Side angle view of Type 98 Ta-Se SPAAG.jpg, ...

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Anti-aircraft Gun
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir-S1). Platforms used include both trucks and heavier combat vehicles such as armored personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, missiles (generally mounted on similar turrets) have largely supplanted anti-aircraft guns, but they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Crank
A bellcrank is a type of crank that changes motion through an angle. The angle can be any angle from 0 to 360 degrees, but 90 degrees and 180 degrees are most common. The name comes from its first use, changing the vertical pull on a rope to a horizontal pull on the striker of a bell, used for calling staff in large houses or commercial establishments. Angles A typical 90 degree bellcrank consists of an "L" shaped crank pivoted where the two arms of the L meet. Moving rods (or cables or ropes) are attached to the ends of the L arms. When one is pulled, the L rotates around the pivot point, pulling on the other arm. A typical 180 degree bellcrank consists of a straight bar pivoted in the center. When one arm is pulled or pushed, the bar rotates around the pivot point, pulling or pushing on the other arm. Mechanical advantage Changing the length of the arms changes the mechanical advantage of the system. Many applications do not change the direction of motion but instead amplify a ...

Type 98 20 Mm AA Machine Cannon
The Type 98 20 mm AA machine cannon was the most common light anti-aircraft gun of the Imperial Japanese Army. It entered service in 1938 and was used until the end of World War II. After World War II this gun was used by the Indonesian Army in the Indonesian National Revolution and North Vietnam in First Indochina War. Design and use The Type 98 20 mm AA machine cannon was the most common light anti-aircraft gun of the Japanese military. The Type 98 designation was given to this gun as it was accepted in the year 2598 of the Japanese calendar (1938).War Department TM-E-30-480 ''Handbook on Japanese Military Forces''. September 1944, p. 400. It entered service that same year and first saw combat in Nomonhan. It was used until the end of World War II. About 80% of the Imperial Japanese Army light AA guns were Type 98s. The gun could be emplaced in about three minutes by an experienced crew or fired inaccurately from its wheels.

Type 98 Ke-Ni Light Tank
The or Type 98A Ke-Ni Ko (also known as Type 98 Chi-Ni light tank) was designed to replace the Imperial Japanese Army's Type 95 Ha-Go light tank, Japan's most numerous armored fighting vehicle during World War II. Although designed before World War II began, production did not start until 1942, with 104 being produced by the end of the war in the Pacific. History and development The Type 98 developed in 1938 was a light tank with the same weight as the earlier Type 95 Ha-Go, but with thicker armor. The first prototype was originally known as the "Chi-Ni Model A" and completed by Hino Motors. The second prototype was originally known as the "Chi-Ni Model B" (a/k/a the "Type 98B Ke-Ni Otsu") and completed by Mitsubishi. This second experimental model had a different suspension system with four larger road-wheels, similar to the US Christie suspension design. During field trials the "Model A" demonstrated superior performance, especially in off-road capabilities, so the Hino design ...

Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Type 98 20 Mm AAG Tank
The Type 98 20 mm AAG (anti-air gun) tank was a Japanese self-propelled anti-aircraft gun using a twin Soki Type II 20 mm anti-air gun. They were combined with the chassis of the Type 98 Ke-Ni. The gun crew worked from a raised platform with a modest amount of protection from the sides - the twin 20 mm gun fired through a large gun shield gave further protection for the crew from that direction. In November 1941, development began on an anti-aircraft version of the Type 98 with a 20 mm AA gun. During development of the AA gun tank, the Imperial Japanese Army experimented with various configurations. Single gun variant An earlier produced single gun prototype was designated the ''Type 98 Ta-Se'' anti-aircraft tank, in November 1941. The name was taken from ''taikū'' ('anti-air') ''sensha'' ('tank'). It was equipped with a single converted Type 98 20 mm AA machine cannon in a circumferential turret. During trials, it was determined that the chassis used for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 2 20 Mm AA Machine Cannon
The Type 2 20 mm AA machine cannon was a Japanese-designed anti-aircraft gun, based on the assembly of the German Flak 38. It entered service in 1942. Design Introduced in 1942, compared to the earlier Type 98 20 mm AA machine cannon, Type 2 20 mm had higher maximum rate of fire, could be elevated to 95 degrees and had a central fire-control system. The central fire-control system developed for the Type 2 could control and direct six of the guns at once. The gun was based on the German 2 cm Flak 30/38/Flakvierling. The Type 2 number was designated for the year the gun was accepted, 2602 in the Japanese imperial year calendar, or 1942 in the Gregorian calendar.War Department TM-E-30-480 ''Handbook on Japanese Military Forces'', September 1944, p. 400.

Experimental SPAAG Ki-To
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 97 Te-Ke Tankette
The was a tankette used by the Imperial Japanese Army in the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in World War II. It was designed as a fast reconnaissance vehicle, and was a replacement for the earlier Type 94 tankette. History and development The origins of the Type 97 lay in a prototype diesel-engine version of the Type 94 Te-Ke developed by Hino Motors in 1936. Although the prototype had a more powerful engine and larger gun, initial trials were not successful and the Japanese Army demanded changes before acceptance. Hino responded with a modified prototype in November 1937, in which the engine was moved towards the rear of the chassis. This design was accepted and full production began in 1938. A total of 616 units were produced from 1938 to 1944 (1 unit in 1937, 56 units in 1938, 217 units in 1939, 284 units in 1940, 58 units between 1941 and 1944).
