SOLID FUEL CHARGE Russian patent published in 2020 - IPC F02K9/18 

Abstract RU 2716122 C1

FIELD: solid fuel.

SUBSTANCE: charge of solid fuel contains organoplastic body made by spiral winding with protective-fixing layer applied on internal surface of the housing, and solid fuel fixed to it by means of protective-securing layer. In the fuel there is a central channel and on the side of the front end face the slit-type compensator of progressive burning in the form of two groups of slots of identical length and different height, wherein the height of the slit of the second group is 0.4–0.6 of the height of the slits of the first group, and the lengths of slits are 0.15–0.3 of the channel length.

EFFECT: such design of solid fuel charge reduces amplitude of thrust oscillations, value of maximum loads and value of passive mass of item.
