Combination recovery rocket overall structure based on general core level

Abstract

The invention provides an overall structure of an assembly recovery rocket based on a general core level. The overall structure comprises the following components of two first-stage liquid oxygen kerosene engines, a first-stage empennage, a first-stage tail section, a first-stage rear transition section, a first-stage kerosene tank, a first-stage inter-tank section, a first-stage liquid oxygen tank, a grid rudder and a second-stage inter-tank section. Two second-stage liquid oxygen kerosene engines, a second-stage kerosene tank, a second-stage tank interval section, a second-stage liquid oxygen tank, an instrument disc, a supporting cabin, an adapter and a belting connection unlocking device; each universal core-level booster comprises a nose cone, a grid rudder, a reaction thrust system, a liquid oxygen tank, an inter-tank section, a coal oil tank, a rear transition section, two liquid oxygen kerosene engines, a tail section and a landing buffer mechanism; front, middle and rear binding connection devices; a satellite fairing; the reverse thrust rocket is arranged between the first core stage and the booster box; and the forward thrust rocket and the reverse thrust rocket are arranged in the second-stage coal oil tank. According to the invention, general core-level assembly recovery is realized for the first time in China, an efficient and reliable assembly rocket recovery scheme is provided, the safety of a rocket falling area can be improved, and the rocket launching cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a return-type recovery rocket configuration based on a general-purpose core stage assembly. Background technique [0002] Entering space, using space and controlling space are the main tasks of aerospace forces, and entering space quickly and efficiently is the basis for using space and controlling space. As the main means of entering space at present, the development of launch vehicles has always been highly valued by the world's space powers, and puts forward higher requirements for new capabilities to enter space. In recent years, the rapid development of low-cost space access capabilities represented by repeated use has greatly reduced the cost of rocket launches. [0003] In order to further enhance my country's ability to enter space, it is necessary to vigorously develop launch vehicle reuse technology. At present, there is a gap in the domestic reuse field.
