SOLID-PROPELLANT CHARGE Russian patent published in 2001 - IPC

Abstract RU 2166660 C1

FIELD: rocketry. SUBSTANCE: solid-propellant charge has case and propellant charge rigidly secured to it by one protective strengthening layer and end collars whose base corresponds to base of propellant charge by its chemical composition; it may be made from polydivinylurethan epoxide. Composition contains also filler made from commercial carbon and the following additional components: maleic anhydride, isomethyl tetrahydrophthalic anhydride, glycedol and panyl-β --naphthylamine. Total amount of additional components ranges from 3.0 to 10% of main components of polymer base of protective strengthening layer and end collars. Thickness of protective strengthening layer ranges from 0,1•10-2 to 2,0•10-2 of outer diameter of propellant charge. EFFECT: enhanced reliability; extended range of temperature application; increased service life; facilitated manufacture at reduced contamination of environment. 4 dwg
