Welcome to the broken dawn

gas pressure pyrotechnics

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
