FIELD: propelling equipment, applicable, in particular, for enhancing the efficiency of propelling devices and jet technology. ^ SUBSTANCE: the component has a massive central subcaliber-type core in the form of an extended cylinder with a sharpened front part and with tail fins in the rear part, leading device-obturator consisting of radially joined sections with the core of the propelled component fastened in its inner hole. The front end face surface of the obturator is made with a ring-shaped recess, concentric relative to the common axis of the core, leading device. Positioned above the outer rear part of the obturator is the casing of the propelled component, whose central axis coincides with the common axis of the core and obturator, the rear part of the mentioned casing rests on the ends of the fins, solid propellant is positioned in the space of the combustion chamber confined by the inner side surface of the casing outer surface of the core, rear end face surface of the obturator and the rear plane of the casing. The outlet section of the combustion chamber is divided into ring sections by the core fins, each section of the obturator has at least one through duct connecting the ring-shaped recess of the front end face surface of the obturator to its end face rear surface, the mentioned duct and its continuation in the space of the combustion chamber are filled with quick-burning propellant, and the rest section of the combustion chamber is filled with slow-burning propellant. ^ EFFECT: the following characteristics are improved: the absolute value of the on-board power reserve, useful power, power supply in the boost stage, economical efficiency, reliability, mass and dimensional characteristics, cost. ^ 6 cl, 4 dwg |
