FIELD: rocketry. SUBSTANCE: proposed housing of solid-propellant rocket engine contains cylindrical shell, end parts including adapter and threaded sections. Thickness of cylindrical shell and thickness of threaded section are equal, respectively, to 0.18- 0.25 and 0.4-0.6 of thickness of adapter section. Inner diameter of cylindrical shell inner diameter of threaded section are equal, respectively, to 1.04-1.05 and 1.01- 1.05 of inner diameter of adapter section. Ultimate strength of threaded and adapter sections is equal to 0.55-0.90 of ultimate strength of cylindrical shell. EFFECT: provision of reliable functioning of rocket projectile with such engine owing to rational design parameters of housing of solid propellant rocket engine. 1 dwg
