AI Technical Summary

Technical Problem

Existing pure chemical rockets are constrained by the Tsiolkovsky equation during the takeoff phase, resulting in an excessively high proportion of propellant used to accelerate the rocket itself. This leads to limitations in launch efficiency, difficulty in precisely controlling acceleration, and the high difficulty in constructing pure electromagnetic orbital infrastructure.

Method used

The system employs an electromagnetic-assisted launch system where the skid platform is tethered to the launch tower throughout the launch process. Through the flexible thrust distribution between the electromagnetic catapult system and the skid platform's own chemical propulsion system, combined with the early start-up of the rocket engine and electromagnetic braking, seamless connection and safe separation are achieved, ensuring stable and controllable acceleration.

Benefits of technology

It achieves "zero-flight recovery" of the skid platform, reduces rocket costs, improves launch efficiency and safety, provides considerable initial kinetic energy, reduces propellant usage, and enhances the system's economy and reliability.
