Abstract From the Canadian patent
The invention relates to a supporting cupola (11) for the propellant (6) of a base-bleed gas generator for a projectile, shell or the like. The supporting cupola (11) is arranged in the discharge aperture (7) of the gas generator and provides a reduced gas outlet area from the base-bleed combustion chamber (4) during launch of the projectile. The supporting cupola (11) is made of a material which is easily eroded by the hot combustion gases, such as magnesium. The reduced outlet area increases the pressure in the combustion chamber during the acceleration stage of the projectile so that an improved ignition of the propellant (6) and reduced risk of extinguishment is obtained. Due to erosion …
