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 with reference to the accompanying drawings and embodiments.

[0270] like figure 1 , The universal rocket recovery cable system based on the cam shape design includes four parts: ground recovery cable device 1, landing rocket 2, following capture control system 3 and hydraulic buffer device 4. like figure 2 As shown, the whole recovery process is divided into an active follow-up capture stage and a passive deceleration buffer stage.

[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 in the oxy surface at a certain height from the ground. Put a slider 1.3 on each smooth guide rail 1.2, the slider can only slide along the guide rail, and the sliding range is the length of the entire guide rail, so the capture range i...

Abstract

The universal rocket recovery cable system based on the cam shape design is suitable for capturing, decelerating and buffering various types of reusable rockets in the landing stage, and the safety and stability of the recovery landing process of the rockets in the non-ideal landing state can be guaranteed; 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. For a specific landing rocket, the target kinematics characteristic of rocket deceleration buffering can be achieved by modifying the shape of the cam according to the design method. 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 universal rocket recovery cable system based on a cam shape design, belonging 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 a variety of rocket recovery schemes. After SpaceX's Falcon 9 successfully recovered the first stage of the rocket and reused it, the landing leg vertical recovery scheme has become the main recovery method for most space agencies. However, the success of this method of recovery requires the rocket to reach the landing platform strictly in a 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 the ability to...
