BALLISTITE SOLID PROPELLANT ROCKET ENGINE Russian patent published in 2001 - IPC

Abstract RU 2168648 C1

FIELD: rocket engines. SUBSTANCE: rocket engine with inserted charges in form of cylindrical grain with central star-shaped channel over entire length working in wide temperature range from -50 C to +60 C; at stress concentration factor at vertices of charge beams ranging from 1.3 to 2.2, solid propellant has standard modulus of elasticity at high temperature of engine combat use within range of 2,1P+60max

≅ E+6СТ

⁰ ≅ 3,3P+60max

, where E+6СТ

⁰ is standard modulus of elasticity of propellant at temperature of 60 C, MPa and

is maximum pressure in engine at temperature of 60 C, MPa. EFFECT: enhanced interballistic characteristics of engine due to high level of mechanical reliability of charge. 5 dwg
