ROCKET SOLID PROPELLANT FUEL CHARGE FOR GAS GENERATOR Russian patent published in 2009 - IPC F02K9/10 F02K9/18 

FIELD: rocket engineering.

SUBSTANCE: invention relates to rocket engineering and is designed to be used primarily in gas-generator and rocket engines charged with solid propellant rocket fuel. The proposed rocket solid propellant fuel charge for gas generator comprises a solid-propellant grain armored on side surface and front face and furnished with a blunt duct arranged on the side of rear burning face. Aforesaid blunt duct is shifted relative to the charge lengthwise axis and parallel to it, the said shift magnitude making 0.12 to 0.40 of the solid-propellant grain OD. The blunt duct sizes meet the ratios covered by this invention.

EFFECT: higher efficiency and reliability of proposed charge with improved output intraballistic characteristics.
