Abstract

The invention discloses a solid-liquid power engine and a rocket applying same, and belongs to the technical field of aerospace. The solid-liquid power engine comprises storage boxes, gas cylinders and thrust rooms, wherein the storage boxes are sequentially arranged into a ring-shaped structure; one thrust room is arranged between any adjacent two storage boxes; each thrust room arranged at one side away from the centre of the ring-shaped structure; one gas cylinder is arranged between each storage box and the thrust room; and each gas cylinder is arranged at one side away from the centre ofthe ring-shaped structure. The storage boxes are sequentially arranged into the ring-shaped structure, so that the cost is reduced; specifically, the thrust rooms adopt parallel type structures, are small in slenderness ratio and are flexible and various in forms; the thrust rooms cooperatively work, so that thrust generated by the solid-liquid engine is utilized to obtain excessive control momentof force, and therefore, posture control of the rocket is realized; and thrust regulation and multi-time start are realized by controlling flow of a liquid oxidant inside the storage boxes, so that general performances are good.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a solid-liquid power engine and a rocket using the same. Background technique [0002] At present, liquid rocket motors and solid rocket motors are mainly used in the power system of the upper stage; among them, the structure of the liquid rocket motor is complex and the maintenance cost is high; the working time of the solid rocket motor is short, the thrust adjustment and repeated start are difficult, and the overall performance is poor . [0003] Therefore, how to provide a solid-liquid engine and a rocket using it, which can not only reduce the maintenance cost of the liquid engine, but also improve the performance of the solid engine, has become an urgent technical problem to be solved by those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a solid-liquid engine and a rocket using it, so as to solve the technica...
