Propellant charge element - for use in e.g. rockets with combustion-inhibiting coating to ensure uniformly increasing combustion gas pressure

摘要

In a propellant charge element =1 face of which has grooves, the bottom of which are situated at a constant distance from the final combustion surface of the construction, while the side walls delimit projections the ends of the projections are covered, at least partly, with a combustion inhibitor. The presence of the inhibitor prevents the development of excessive pressure at the start of combustion, allowing the steady build-up of pressure desirable for accelerating a rocket.
