FIELD: rocketry.
SUBSTANCE: invention relates to gas generator and rocket engines with solid propellant charges. Proposed solid-propellant charge includes side and end face-restricted burning grain rigidly connected to front bottom of engine body. Charge is fastened on body bottom over surface of restricted burning end face by means of liquid viscous polymerizing compound. Side clearance between body and side surface of charge from side of restricted burnished end face is also up with polymerizing compound over 0.2 - 0.8 of length of charge. Adhesion of polymerizing compound to side surface of charge is prevented by application of layer of polyethylene onto side surface of charge.
EFFECT: improved efficiency and operation reliability of solid propellant charge.
