By creating a pressure differential in the barrel after the shell leaves, the bore evacuator causes most of the propellant gases and combustion residues to exit via the muzzle. Thus, when the breech opens for reloading, those gases and residues do not escape into the crew compartment and pose a hazard to the gun crew. [1]
The endurance of the cylinder can be calculated from the volume, pressure and breathing rate of the user. The formula: volume (in liters) × pressure (in bars) / 40 (litres per minute) - 10 minutes (the 10 minutes is a safety margin, or reserve), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - 10 = 35 minutes working duration.
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high speed. Tanks in this state are capable of breaking through a brick wall. [19]
In response to the information about the T-54A tank the US had to develop new M60 tank (production started in 1959) heavier than 46 metric tons, which M74 armored recovery vehicle was unable to retrieve. The design of a new ARV vehicle was based on the chassis and parts of the automotive component of the M48 Patton and M60 tanks. The original ...
