Description

Rocket launching system and supporting device thereof

Technical Field

The application relates to the field of rocket launching, in particular to a rocket launching system and a supporting device thereof.

Background

The rocket launching has three launching modes of ground launching, air launching and offshore launching. Regardless of the launching mode, after the rocket is erected on the launching pad device, stability of the rocket needs to be ensured, and the state of the rocket is prevented from being influenced by external environmental factors. Especially for offshore launching, the offshore launching platform is violent in shaking due to external interference of sea waves, ocean currents, wind and the like, and the situation of attitude drift exists, so that the state of a rocket erected on a launching pad device is influenced.

At present, the anti-overturning arm hinged to the launching pad device at the lower end is used for holding up the rocket erected on the launching pad device, so that the stability of the rocket is ensured, and the severe shaking of the offshore launching pad is avoided. However, during rocket launching, the anti-overturning arm needs to rotate outwards around the position where the lower end of the anti-overturning arm is hinged with the launching platform device, so that the anti-overturning arm is unfolded to enable the rocket to be launched smoothly. However, since the anti-overturning arm is easy to impact with the launching pad device when being rotated and unfolded, the anti-overturning arm is easy to rebound and vibrate under the impact, thereby easily damaging a rocket launching system.

Therefore, how to avoid the rebound and vibration of the anti-overturning arm of the rocket launching system, so as to avoid damage to the rocket launching system, is a technical problem that needs to be solved by those skilled in the art at present.
