METHOD OF SOLID PROPELLANT CHARGE CHANNEL ARMOURING Russian patent published in 2008 - IPC C06B21/00 C06D5/00 

FIELD: weapons and ammunition.

SUBSTANCE: method offered implies solid propellant charge channel armouring using pasting an armour cover into the channel. Before that, an adhesive substratum is applied to the channel section being armoured. Then, an armoured floor is applied to the expander buttered by anti-adhesive mixture. The outer profile of armoured floor is to comply with cross-section profile and with length of channel section being armoured. Then the expander with armoured floor is glued into charge channel, the armour cover is pressed to the channel surface and the expander is extracted. The expander surface, contacting with armoured floor, can have screwed protrusions. Armoured floor can be made from mixture based on acetylcellulose or ethylcellulose. Polyisobutylene rubber substance can be used as anti-adhesive material, and acetylcellulose or ethylcellulose-based lacquers can be used as adhesive substratum. Armoured floor can be applied to expander in a press mold of automatic molding machine.

EFFECT: reliability of armoured floor bracing to the surface of solid propellant charge channel.
