Description

Technical Field

[0001] The present invention relates to the technical field of reusable carrier rocket recovery, in particular to a magnetic levitation recovery device and a recovery system for a carrier rocket. Background Art

[0002] With the development of aerospace technology, space activities are becoming more frequent, and the demand for rockets and their launch capabilities is increasing. How to launch satellites more flexibly, efficiently and economically is one of the key research directions in the current aerospace field.

[0003] Rocket construction costs primarily consist of the rocket body and fuel. Rocket construction no longer solely focuses on advanced performance indicators, but instead prioritizes the practical feasibility and affordability of specific solutions. For example, the Starship innovatively uses inexpensive stainless steel in its structural design. The blind pursuit of advanced technology while ignoring affordability places enormous pressure on the spacecraft development process. Improving spacecraft reusability is one of the primary ways to reduce costs.

[0004] Rocket recovery technology is a shining jewel in the field of aerospace technology, a comprehensive reflection of aerospace technological strength. Therefore, it has attracted great attention from major space powers. Liquid rocket recovery solutions are currently being implemented in China, and US companies SpaceX (using liquid oxygen / methane propellants) and Blue Origin have successfully recovered rockets on multiple occasions. For example, the rocket recovery technology employed by SpaceX in its recent launches involves decelerating the rocket stage during descent by igniting the main engine, while simultaneously adjusting the flight attitude of the rocket stage with the attitude control engine to ensure a near-vertical descent. As the descending rocket stage approaches the ground, the retracted support legs deploy, allowing the rocket to rest smoothly on the landing surface (e.g., a ground or offshore platform).

[0005] Currently, most launch vehicle recovery methods still rely entirely on propellant fuel for recovery and landing. Most commercial companies around the world develop recoverable rockets for single-rocket recovery. There is an urgent need to develop new, more maneuverable, flight-based recovery rockets to meet the growing demand for space rocket launch and recovery.

[0006] Through this project, magnetic levitation technology will lead to technological traction and diversified development. In the future, the newly developed magnetic levitation recovery technology will not only be used for rocket recovery, but will also be expanded to deep space launch missions such as lunar exploration and landing, Mars exploration and landing. At the same time, it is necessary to develop new structural materials with lower costs and higher efficiency to meet higher demands. Summary of the Invention
