End cover and first-stage integral recovery low-cost second-stage low-orbit carrier rocket

Abstract

The invention discloses an end cover and first-stage integral recovery low-cost second-stage low-orbit carrier rocket which comprises a first-stage rocket body, a rocket sleeve cover and a second-stage rocket body, wherein the rocket sleeve cover comprises a barrel cover, an end cover shell section and an end cover, the barrel cover is arranged at the front end of the first-stage rocket body, and the barrel cover is used for containing the second-stage rocket body; the bottom of the barrel cover is provided with an adaptive support used for installing a second-stage rocket body, the inner wall of the barrel cover is provided with a sliding rail combination, the sliding rail combination is connected with the second-stage rocket body in a sliding fit mode, the front end of the second-stage rocket body is provided with a satellite adaptive support, and a satellite load is installed on the satellite adaptive support; the end cover is composed of a plurality of petals hinged to an end cover shell section, the multi-petal end cover is in a hemisphere shape after being folded, and opening and closing of the end cover are controlled through an end cover actuator; and a reverse thrust rocket is further arranged at the front end of the inner wall of the end cover shell section. According to the end cover and the first-stage overall recovery low-cost second-stage low-orbit carrier rocket, 100% overall recovery can be achieved, repeated use can be achieved after detection and evaluation, and the reuse value is higher.

Description

technical field [0001] The invention relates to the technical field of aerospace rockets, in particular to a low-cost two-stage low-orbit launch vehicle for integrated recovery of an end cover and a first stage. Background technique [0002] With the continuous development of the aerospace field at home and abroad, how to reduce the cost of space launch is one of the main challenges facing the entire space industry. The development of commercial space has put forward higher requirements for low-cost launches and low-cost rockets! Especially for some low-altitude and high-speed flight test launches, the recovery and reuse of the vehicle and its payload is an important measure to reduce costs. Since the middle of the last century, the major aerospace countries in the world have continued to carry out research and experiments on reusable space transportation systems. From the perspective of configuration and technical characteristics, reusable vehicles can be divided into two ...
