Type 4 Ho-Ro
The was based on an already existing reinforced Type 97 Chi-Ha medium tank chassis developed by the Imperial Japanese Army in World War II. Development Inspired by the Grille series of self-propelled artillery vehicles developed by Nazi Germany during World War II, wherein a 15 cm sIG 33 infantry support gun was mounted on a tracked chassis, engineers at the Army Technical Bureau resolved to do the same. Just like the German Grille, the Ho-Ro was based on an already existing chassis. Production was assigned to Mitsubishi Heavy Industries. The exact number produced is uncertain, but 12 units were built in 1944. Design The chassis selected was a modified Type 97 Chi-Ha medium tank chassis. On to this platform, a Type 38 150 mm howitzer based on a design by the German arms-manufacturer Krupp was mounted, but dated from 1905 and had been withdrawn from service as being obsolete in 1942. The main gun could fire Type 88 APHE rounds and HEAT rounds, if necessary. Given its br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns ( tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

HEAT
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
