space engineering. SUBSTANCE: solid-propellant charge has body, protective securing layer, star-shaped passage in bottom section of charge, adapter and cylindrical sections. Cylindrical section of passage has diameter equal to outer diameter of beams of star-shaped passage at end of transient section. Minimum area of flow section of star-shaped passage range from 0.004 to 0.005 of area of burning section of star-shaped passage as far as indicated section. Initial thickness of burning dome of charge in area of star-shaped passage at bottom end face ranges from 0.85 to 0,95e2, where e2 - is initial thickness of burning dome of charge in area of star-shaped passage at the beginning of transient section. EFFECT: increased coefficient of volumetric load at reduced spread in power characteristics. 2 dwg
