Problems solved by technology

Strict requirements on landing status and high technical difficulties in software and hardware have resulted in more than 90% of Falcon 9 first-level recovery failures occurring in the landing section, which also limits the development of research on landing leg vertical recovery schemes in my country. Therefore, it is necessary to propose independent innovations my country's rocket recovery program promotes the development of reusable space delivery systems

Embodiment Construction

[0269] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0270] like figure 1 , The rocket recovery cable system includes a ground recovery cable device 1, a landing rocket 2, a following capture control system 3 and a hydraulic buffer device 4. like figure 2 As shown, the whole recycling process is divided into the active follow capture phase and the passive deceleration buffer phase.

[0271] like image 3 As shown, the ground recovery cable device is built on four vertical rigid supports 1.1, and four smooth straight slide rails 1.2 are respectively connected to two adjacent supports 1.1, and a square recovery area is constructed at a certain height from the ground in the oxy plane. Put a slide block 1.3 on each smooth guide rail 1.2, the slide block can only slide along the guide rail, and the sliding range is the length range of the entire guide rail, so the capture range is the entire recycling area...

Abstract

The invention aims to provide a rocket landing recovery system which is suitable for capturing, decelerating and buffering various types of reusable rockets in a landing stage, and can ensure the safety and stability of a rocket recovery landing process in a non-ideal landing state. According to the system, the recovery cable is woven into the capturing frame, the motor is used for driving the capturing frame to actively follow and capture the landing rocket, the landing point deviation range and the landing attitude angle deviation range of the rocket are widened, and the technical requirement for an on-rocket navigation guidance control system is lowered. According to the system, different landing rockets can be recovered by adjusting the size of the capturing cable frame and the capability of the deceleration buffer system. The system has the advantages of being simple in structure, easy to implement, good in universality and low in technical difficulty, the success rate of rocket recovery is increased, and robust recovery is achieved.

Description

technical field [0001] The invention relates to a rocket landing recovery system, which belongs to the field of aerospace. Background technique [0002] Recycling and reusing rockets can greatly reduce the cost of launching rockets and exploring space. Since the 1950s, astronauts at home and abroad have gradually taken rocket recovery technology as a research hotspot and explored various rocket recovery schemes. After the Falcon 9 of SpaceX in the United States successfully recovered and reused the first-stage section of the rocket, the landing leg vertical recovery solution has become the main recovery method for most space agencies. However, the success of this recovery method requires the rocket to reach the landing pad in a strictly vertical attitude, with zero lateral velocity and zero vertical velocity. In order to meet this requirement, the rocket’s software and hardware supporting facilities need to meet: the rocket’s engine needs to have a large thrust adjustment ...
