Abstract
An improved arrangement for more efficiently igniting and thereafter maintaining an optimum burning efficiency of a hollow, solid propellant charge cartridge disposed in a combustion chamber at the rear end of a rocket or other ballistic projectile is described. A support tube is mounted for extension coaxially into the hollow interior of the charge cartridge with a radial clearance therebetween. The rear end of the support tube is carried within the locking member at the rear end of the combustion chamber, so that upon bursting of a rupture disc between the locking member and the rear end of the combustion chamber, both the locking member and the support tube can be propelled axially rearwardly out of the combustion chamber. The advantageous function of the support tube to absorb radial acceleration forces during firing of the rocket, is preserved, while thereafter the deleterious effect of having the support tube remain in place during the ignition of the main propellant charge is obviated.
