SOLID ROCKET PROPELLANT CHARGE Russian patent published in 2005 - IPC

FIELD: rocketry.

SUBSTANCE: proposed solid propellant rocket charge has central and peripheral unrestricted- burning pots of shaped profile. Channels of peripheral pots have triangular profile with fillets at vertices. Evolutes of profiles of peripheral pot channels coincide with evolutes of their external profile. Central pot has circular contour of axial channel. Thickness of burning dome of peripheral pots is equal to 1.0-1.1 of thickness of burning dome of central pot. Outer surface of central pot has longitudinal ridges of triangular profile whose number is equal to number of peripheral pots at length of base over chord of external profile of central pot no more than double thickness of burning dome of central pot.

EFFECT: high density of filling the engine combustion chamber with propellant; reduction of thermal loads on engine combustion chamber.
