METHOD FOR DESTRUCTION OF SOLID PROPELLANT CHARGE Russian patent published in 2010 - IPC F42B33/06 F42D5/04 C06B21/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to disposal of solid propellant rocket engine (SPRE) with tightly fixed solid propellant charge, neutralisation of solid propellant (SP) wastes. In proposed method case of rocket engine with charge without covers is placed into tight reservoir, filled with destructive mixture until the change is fully submerged. Pressure from 0.3 to 1.5 MPa is developed, as well as temperature of not lower than 120°C, but not exceeding temperature of thermal decomposition of propellant, and maintained until complete structural destruction of charge. For this purpose destructive mixture is aqueous solution of surfactants and mineral salts. Pressure in reservoir is developed by means of solution injection by piston pump, and temperature - by coolant supply into reservoir jacket.

EFFECT: invention provides for charge destruction directly in rocket engine body with elimination of application of aggressive and toxic substances.
