FIELD: engines and pumps.
SUBSTANCE: rocket solid-propellant charge incorporates channel grain furnished attached to rocket engine front bottom. Grain front end face is furnished with armored coat housing attachment unit representing axially symmetric reinforcing carcass coupled with armored centered in armoring body relative to charge axis. Said carcass represents thin-wall perforated annular plate projecting towards grain and coupled with rods or sleeve. Rods are arranged in parallel to charge axis and extend from armoring body to get linked to rocket engine front bottom. Aforesaid sleeve extends from armoring body to get coupled with rocket engine front bottom.
EFFECT: higher reliability of solid-propellant charge, ruling out regressive residue at rocket engine operation termination and lower smoke formation.
