The gas laws are now explained by the microscopic behavior of gas molecules: Boyle's Law: The pressure of a gas is inversely proportional to its volume. A container's volume and surface area are obviously proportional. Based on the pressure equation, an increase in volume (and thus surface area) will decrease pressure.

Propellant - Wikipedia

In rockets and aircraft, propellants are used to produce a gas that can be directed through a nozzle, thereby producing thrust. In rockets, rocket propellant produces an exhaust, and the exhausted material is usually expelled under pressure through a nozzle. The pressure may be from a compressed gas, or a gas produced by a chemical reaction.

1) Effects of blast pressure on the human body

To demonstrate the effects of explosion pressure on objects, an LLEM test moved a 1,560 pound object about 79 feet. The explosion pressure on the object was estimated at 3.5 psi and lasted less than 7 milliseconds. The exposed cross-sectional area is estimated at about 900 square inches, and therefore, the total force on the object was about 3,150

Theoretical energy release of thermites, intermetallics ...

Abstract. Thermite (metal oxide) mixtures, intermetallic reactants, and metal fuels have long been used in pyrotechnic applications. Advantages of these systems typically include high energy density, impact insensitivity, high combustion temperature, and a wide range of gas production.

AD 042

If this gas is confined in the delay column, the resulting pressure causes erratic burning times, but the pressure may be reduced easily by venting the delay colun to the atmosphere or into very small internal expansion chambers. Other methods have been considered(7 8;9J10! I'2) for employing pyrotechnic mixtures in timing devices.

Gas Pressure Pyrotechnics

The build-up of gas pressure is instantaneous. GeminiGuide PYROTECHNICS and RETRO ROCKET SYSTEM. The gas pressure moves the release piston forward, which enables the four locking pins to cam inboard, releasing the main piston. The gas pressure causes the main piston, with attached actuator, to move through the length of the actuator housing.
