Abstract : Solid fuel power units sometimes experience failure due to the motor exceeding its designed capacity and this leads to an explosion. One of the most frequent causes of this phenomenon are the numerous fissure like cavities, formed basically during the technological process, that are usually present in solid fuel. When the combustion front approaches the edge of such a cavity, as a result of increased pressure in the combustion chamber, the combustion quickly envelopes all of the cavity. In a sufficiently narrow and long cavity where gas encounters difficulty in escaping, the pressure in the cavity reaches such a magnitude, that the system begins to operate in a unstable manner. A theoretical description of indicated phenomena is presented. (Author)
