AI Technical Summary

Technical Problem

In existing technologies, the positional deviation between the launch vehicle and the launch pad results in a complex structure, high manufacturing cost, and difficulty in installation and disassembly of the release mechanism. It is also difficult to achieve coaxial control of the pulling force and the separation direction, which affects the reliability and safety of the release process.

Method used

The design employs a sliding rail and universal joint. By adjusting the position of the sliding pin within the X-shaped groove and rotating the sliding rail, the traction pin can be infinitely adjusted, ensuring that the pulling force direction is coaxial with the socket on the rocket. This simplifies the structure and improves the ease of installation and disassembly.

Benefits of technology

It achieves adaptability to positional deviations on different batches of rockets, ensures consistency of the traction force and direction of the separation steel cable, has a simple structure, high safety, and is easy to install and disassemble, thus reducing manufacturing costs.
