MANUFACTURE METHOD FOR DESTRUCTIBLE COVER OF LAUNCHING TUBE CONTAINING SPHERICAL SEGMENT Russian patent published in 2017 - IPC F41F3/77 

FIELD: weaponry and ammunition supplies.

SUBSTANCE: manufacture method for destructible cover of launching tube containing spherical segment of glass fibre reinforced plastic (GRP), includes providing basic matrix from a material which is identical to the material of the spherical segment, contact moulding of spherical segment billets by coating the basic matrix with fiberglass impregnated with the binder, binder curing. When forming a spherical segment form at least two fibreglass substrate so that the thickness of the previous sublayer is equal to the thickness of the subsequent sublayer. Subsequent sublayer is applied on top of the previous sublayer after partial binder curing in the previous sublayer, machining a spherical segment billet for specified sizes, splitting the spherical segment into shares to form gaps, filling gaps with casting composition of a strength which is lower than the strength of the material of the spherical segment, with the formation of a single spherical segment.

EFFECT: improvement of operational reliability of the cover.
