Polymer-bonded explosives have several potential advantages: If the polymer matrix is an elastomer (rubbery material), it tends to absorb shocks, making the PBX very insensitive to accidental detonation, and thus ideal for insensitive munitions.
Electrothermal-chemical (ETC) technology is an attempt to increase accuracy and muzzle energy of future tank, artillery, and close-in weapon system [1] guns by improving the predictability and rate of expansion of propellants inside the barrel.
PEX – platform express toolstring (resistivity, porosity, imaging) PFC – perforation formation correlation; PFD – process flow diagram; PFD – probability of failure on demand; PFE – plate/frame heat exchanger; PFHE – plate fin/frame heat exchanger; PFPG – perforation plug log; PFREC – perforation record log; PG – pressure ...
The XM360 is an American experimental 120 mm tank gun developed by U.S. Army's Watervliet Arsenal, Benét Laboratories for use by General Dynamics Land Systems (GDLS) on one of their proposals for the Future Combat Systems (FCS). [1]
A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
It was first invented in 1955 by H.B. Sargent, R.M. Poorman and H. Lamprey and is applied to a component using a specifically designed detonation gun (D-gun). The component being sprayed must be prepared correctly by removing all surface oils, greases, debris and roughing up the surface in order to achieve a strongly bonded detonation spray ...
The PP-91 is a simply designed, easy to manufacture selective fire submachine gun designed by Yevgeny Dragunov (the designer of the SVD sniper rifle).. It is blowback operated and fires from a closed bolt, allowing for more accurate shooting than would be possible from an open bolt design.
