FIELD: transport.
SUBSTANCE: invention relates to armored insertion charges of rocket solid propellants (RSP). Proposed charge represents RSP grain with armor coat on its surface. Said armor coat represents a self-adhesive δ-thick tape based on softened rubber that inhibits ignition of the grain armored surface for preset time of charge ignition. Note here that tape length exceeds grain surface circumference by at least 3δ. Said tape is wrapped around said grain through 360° with rebate joint along its length formed by skewed cuts at angle α, not exceeding 45°, to grain surface.
EFFECT: higher fire safety in fabricating insertion RSP charges.
