FIELD: rocketry.
SUBSTANCE: invention can be used in liquid propellant and oxidant motors. According to invention, in proposed vortex rocket motor containing combustion chamber in form of cylinder with bottom at one side and dome to change into neck at other side, and nozzles to deliver propellant and oxidant, cone is made on bottom of chamber to turn vortex, some nozzles are uniformly spaced on dome to provide formation of vortex and designed to deliver propellant and part of oxidant, and one nozzle is located in cone to turn vortex and is designed to deliver remaining part of oxidant. Propellant and oxidant delivery nozzles are arranged tangentially relative to circumference of dome at angle of 60° to dome surface. motor is furnished with deflecting blades to compensate for reactive rotation of chamber secured on cone which is mated with chamber neck.
EFFECT: simplified design, reduced mass.
