Rocket three-level solid-liquid main power and attitude control integrated system and method thereof

Abstract

The invention discloses a rocket three-level solid-liquid main power and attitude control integrated system and a method thereof, and relates to the technical field of aerospace. The rocket three-level solid-liquid main power and attitude control integrated system comprises a gas cylinder, a gas circuit stop valve, an oxidant storage tank, a main power system and an attitude control power system;the gas cylinder is communicated with the oxidant storage tank through the gas circuit stop valve; the main power system and the attitude control power system are respectively communicated with the oxidant storage tank; and the main power system includes a solid fuel. The rocket three-level solid-liquid main power and attitude control integrated method is suitable for the rocket three-level solid-liquid main power and attitude control integrated system. The invention aims to provide the rocket three-stage solid-liquid main power and attitude control integrated system and the method thereof inorder to solve the technical problems of overall complexity and structural quality increase of a power system due to the fact that a solid rocket engine is adopted as a main power engine and a liquidrocket engine is adopted as an attitude control engine in the prior art to a certain extent.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a rocket three-stage solid-liquid active force and attitude control integrated system and method thereof. Background technique [0002] The degree of development in the aerospace field is one of the important criteria to measure a country's space exploration capabilities and determine whether its comprehensive national strength is strong. The rocket engine is the heart of the rocket, and the design level of the rocket engine determines the level of aerospace technology of a country. [0003] The rocket's third-stage main engine mainly works on the basis of the shutdown of the second-stage rocket, so that the carried payload can reach the specified speed requirement. Existing rockets are usually equipped with an additional attitude control engine group in addition to the main power system to realize the attitude adjustment control of the rocket during flight; that is, the role...
