The gas pressure is ported into the cylinder and enters an orifice in the base of the indexing bar. The gas pressure is then ported through the hollow inner piston extension and exerts force on the bottom of the outer piston, causing it to sever the retaining pin and extend the outer piston with indexing bar attached.

Explosive and pyrotechnic devices transform a small input of mechanical or electrical energy into a higher level of mechanical or thermal energy, which is then applied to do practical work on a one-time basis. This is accomplished by releasing the stored energy in an explosive or pyrotechnic mixture through a precisely con…

The pressure of a sample of gas is measured at sea level with an open-end Hg (mercury) manometer, as shown to the right. Determine the pressure of the gas in: (a) mm Hg (b) atm (c) kPa. Solution: The pressure of the gas equals the hydrostatic pressure due to a column of mercury of height 13.7 cm plus the pressure of the atmosphere at sea level ...
Explosives are classified as 'low' and 'high', depending upon the rate at which they decompose. At a relatively low rate of decomposition, these materials undergo fast burning, and produce huge amount of gas. These are generally known as propellants, and the laser ignitibility of such materials are also discussed in the chapter.
We design mechanical, hot gas pressure and detonation initiation with single or redundant features – either explosive loaded or inert. If your needs require it, an internal time delay element can be added for sequencing requirements.
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.
The M-796 and BBU-35B use a double base NC/NG propellant for producing gas pressure against the countermeasure piston for ejection (and to ignite a Mg-Teflon flare) from the aircraft dispenser.
