ABSTRACT:
A hollow projectile, to be launched by rocket or fired from a cannon, has a central venturi tube that vents to the external environment near the forward end of the projectile. A pressurized liquid or a solid, combustible matrix that contains a gas or colloid producing material surrounds the venturi tube. This material is released through the venturi tube either by burning the matrix or by rupturing a diaphragm that retains the liquid. A timer, started by an accelerometer in response to the acceleration of the projectile when it is launched, fires an igniter or an explosive fuse to release the gaseous material. Spring loaded valve means, which normally closes the venturi tube, is forced open by gas pressure within the tube to permit discharge of gaseous material into the external environment. This valve means establishes a threshold pressure within the projectile that helps to ignite the matrix and to maintain combustion thereof, and to accelerate the gases being discharged from the projectile.
