FIELD: power engineering.
SUBSTANCE: when manufacturing a composite solid propellant charge, a composite solid propellant is injected into a press mould via a stock line. The press mould is a rocket engine vessel, the inner cavity of which is connected to atmosphere via bleeding holes. Bleeding holes are arranged in the front bottom of the vessel at the joint of a detaching collar and a cylindrical sleeve, which armours the charge channel. At the side of bleeding holes flanging is arranged as directed inside the vessel, the height of which closes bleeding holes, and T-shaped flanging is arranged at the other end of the sleeve to connect the stock line to the press mould.
EFFECT: invention makes it possible to provide for defect-free manufacturing of a composite solid propellant charge, excluding air capsulation in a propellant in an inner cavity of a rocket engine vessel closed at all sides.
