SOLID ROCKET PROPELLANT CHARGE (VERSIONS) Russian patent published in 2009 - IPC F02K9/10 

FIELD: weapons.

SUBSTANCE: proposed charge of solid rocket propellant is in form of a blasting cartridge, whose lateral surface is armour plated. The armour plate consists of a polymer binder and a reinforcement material with the following ratio of components, in wt. pts: polymer binder from 90 to 60, reinforcement material from 10 to 40. The invention proposes two versions of the binder. The reinforcement material is in form of low twist cotton yarn or cotton viscose or lavsan bands, which are wound on a rotating charge during the amour plating process. Solidification of the amour plate on the charge takes place at 15...40°C temperature for a period of 24-96 hours.

EFFECT: increased erosion resistance and thermal protective capacity of the armour plate, and increased rate of its polymerisation.
