Clarence Walton Musser (April 5, 1909, Mount Joy, Pennsylvania [1] – June 8, 1998) inventor of strain wave gearing and also credited with over 250 major inventions and discoveries. [ 2 ] Some of his inventions were the Army recoilless rifle , aircraft personnel catapults, instrumentation for underwater detonation testing.
A 10 July 2010 test validated the Triomphant-class submarine's capacity to launch the M51 in operational conditions. [18] On 5 May 2013, an M51 flight test missile failed after being fired by a submerged ballistic missile submarine off the coast of Brittany. This was the first failed launch of the M51 after five successful launches since 2006. [19]
The M51 Skysweeper (Gun, M51, Antiaircraft or Gun automatic, 75-mm T83E6, and E7, recoil mechanism, and loader rammer) was an anti-aircraft gun deployed in the early 1950s by both the U.S. Army and U.S. Air Force. It was the first such gun to combine a gun laying radar, analog computer (director) and an autoloader on a single carriage.
Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...
The use a variety of fuzes, a M61 pressure/friction fuze, a "tentacle" fuze with four hoses that triggers the mine when two of the opposite tentacles are crushed, and a tilt rod fuze. The M51 and M52 are broadly similar with a thin fibreglass cases, the principal difference being the M52 is slightly larger than the M51.
Takeoff weight components. The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
Weight machines commonly use specialized sets of plates (called "weight stacks"), consisting of a set of rectangular plates mounted on rails. Through a cable and pulley system, the burden is transferred to the machine's user. By placing a pin in the stack that causes the cable to pull on each plate above the pin, the weight is selected.
The M-1952 Flak vest, or "Armor, Body, Fragmentation, Protective, Vest Type, M-52" was a flak vest designed for the United States Marine Corps during the Korean war.. Following the joint US Army and Marine Corps designed M51 Flak Jacket, the M-52 used aluminum plates instead
