ABSTRACT:
A solid grain block is housed in a casing with interposition of a heat protection layer and defines a combustion chamber, and a separation zone is formed between the solid grain and the heat protection layer of the rocket motor bottom structure by means of a skin detached from said layer and adhering to the solid grain, at least one of the two parts constituted by the detached skin and the heat-protection layer of the rocket motor bottom structure being provided with projections or teeth to ensure a minimum spacing of the detached skin with respect to said layer and to give easy access to the gases into the separation zone.
