T48 Gun Motor Carriage
The T48 57 mm gun motor carriage was a self-propelled anti-tank gun produced by the Diamond T company in 1943 for the United States. The design incorporated a 57 mm gun M1, a US production of the British Ordnance QF 6 pounder, mounted on an M3 half-track. A total of 962 vehicles were produced from 1942 to 1943. It had originally been planned that Britain would receive all of the examples produced through Lend-Lease, intending to use them in the Western Desert, but by the time they arrived the campaign was over. Additionally, the purpose-built M10 tank destroyer, armed with a 3-inch gun (and later a 17-pounder gun in British service) had begun to enter production. As a result, the British transferred 650 half-tracks to the Soviet Union under the Soviet Aid Program. Britain retained 30 and the remainder were taken by the US; except for one kept by the U.S. Army, these British and American vehicles were converted back to standard M3 half-tracks. The Soviets called it the SU-57 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philippines Campaign (1941–1942)
The Philippines campaign (, , ), also known as the Battle of the Philippines () or the Fall of the Philippines, was the invasion of the Commonwealth of the Philippines, Philippines by the Empire of Japan during the Pacific War, Pacific Theater of World War II. The operation to capture the islands, which was defended by the U.S. and Philippine Armies, was intended to prevent interference with Japan's expansion in Southeast Asia. On 8 December 1941, several hours after the attack on Pearl Harbor, Japanese planes began bombing U.S. forces in the Philippines, including Attack on Clark Field, aircraft at Clark Field near the capital of Manila on the island of Luzon. Japanese landings on northern Luzon began two days later, and were followed on 22 December by Japanese invasion of Lingayen Gulf, major landings at Lingayen Gulf and Japanese invasion of Lamon Bay, Lamon Bay by the Japanese Fourteenth Area Army, Fourteenth Army under Masaharu Homma.

Gun Laying
Gun laying is the process of aiming an artillery piece or turret, such as a gun, howitzer, or mortar, on land, at sea, or in air, against surface or aerial targets. It may be laying for either direct fire, where the gun is aimed directly at a target within the line-of-sight of the user, or by indirect fire, where the gun is not aimed directly at a target within the line-of-sight of the user. Indirect fire is determined from the information or data that is collected, calculated, and applied to physical coordinates to identify the location of the target by the user. The term includes automated aiming using, for example, radar-derived target data and computer-controlled guns. Description Gun laying is a set of actions to align the axis of a gun barrel so that it points in the required direction. This alignment is in the horizontal and vertical planes. A gun is "traversed" (rotated in a horizontal plane) to align it with the target, and "elevated" (moved in the vertical plane) ...

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Volute Spring Suspension
The vertical volute spring suspension system is a type of vehicle suspension system which uses volute springs to compensate for surface irregularities. This type of the suspension system was mainly fitted on US and Italian tanks and armored fighting vehicles starting from throughout the 1930s up until after the end of the Second World War in 1945. Principle The horizontal arms connected to the road wheels are cranks that drive the vertical arm up and down. The vertical arm connects to the volute spring in the box-shaped area above. Development During the 1930s, many innovations in the components of light tanks would make US tanks considerably more reliable. These included rubber-bushed tracks, rear mounted radial engines and the vertical volute spring suspension. A volute spring is a compression spring in the form of a cone (a volute). Under compression the coils slide over each other, affording a long travel. The result is more stable and powerful than any leaf, coil, ...

Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
