FIELD: rocketry.
SUBSTANCE: proposed solid-propellant charge consists of solid-propellant grain restricted along side surface and end face with cellulose acetate-based inhibitory coating with synthetic glue-based sheathing film layer applied over inhibitory coating. Through central channel is made in charge. Surface of central though channel made in charge is restricted together with side surface and front end face of charge with possibility of removal of part inhibitory coating from side of burning eng face of side surface. Ratio of diameter of solid-propellant grain (D) and diameter of channel (d) is 2.0<D/d<5.0.
EFFECT: reduced smoking, increased destructive effect of cumulative warhead of shell, optimum conditions of realization of cruise and acceleration and cruise operating conditions of rocket engine.
