    Pyrotechnics is the science and craft of using self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words pyr ("fire") and tekhnikos ("made by art"). Pyrotechnics includes, among other things, fireworks; safety matches; oxygen candles; explosive bolts and other fasteners; parts of automotive airbags; and gas-pressure blasting in mining, quarrying, and demolition.

PYROTECHNICS, PROPELLANTS AND EXPLOSIVES

They generate a large gas stream (like all other pyrotechnics) that is channelled with one free end to give propulsive thrust to a projectile or to the combustor body. The main difference between rocket propellants and gun propellants is the working pressure reached, which in rockets is around 10 MPa, and in guns more than 100

Combustion Properties of Gas-Generating Pyrotechnics

Abstract This work focuses particularly on solid energetic materials designed to produce high-pressure gas for pressurizing or inflating devices. In coot gas generators sodium azide is often used. Unfortunately, this chemical exhibits drawbacks concerning toxicity and yield of gas. Another gas-generating agent is double base propellant, which has traditionally been used in the rocket-industry.

Propellant Wikipedia

In aerosol spray cans, the propellant is simply a pressurized gas in equilibrium with its liquid (at its saturated vapour pressure).As some gas escapes to expel the payload, more liquid evaporates, maintaining an even pressure. Used to propel solid objects. Technically, the word propellant is the general name for chemicals used to create thrust. For vehicles, the term propellant refers only to
