Device for compensating for volume changes in a solid rocket motor propulsion charge

摘要

A device for compensating for the volume changes resulting from heat differences in a solid rocket motor propulsion charge which is arranged in a firmly adhering manner in the combustion chamber housing via an external thermal insulation layer, compensation holes running in the longitudinal direction being provided in the radially outer region of the propulsion charge, which compensation holes are clad with thin burning containment layers and/or are provided with an insulating filling which burns back with the burning front. <IMAGE>
