Technical Field

[0001] The utility model relates to the technical field of offshore launch platforms, in particular to an offshore regulating platform and a spacecraft launching ship. Background Art

[0002] Sea launch is the future development direction of spacecraft launch. Compared with land launch, it has the advantages of maneuverability, wide coverage area, and engine fuel saving. However, compared with the stable environment during land launch, launching at sea will face a complex sea environment. Under the influence of wind and waves at sea, the launch vehicle will produce complex movements, affecting the attitude of the spacecraft at launch and having a great impact on the attitude control of the spacecraft.

[0003] The current spacecraft operating platform is only suitable for land-launched spacecraft, and there is still a lack of an operating platform for marine spacecraft that can cope with complex sea conditions.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an offshore adjustment platform and a spacecraft launching ship are proposed. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, each sub-stage of the split rocket is transported by a ship to the spacecraft launching platform of the present application separately to reduce the carrying burden of the ship. Each sub-stage is unloaded from the ship's hold and transferred to the assembly platform by the tower crane on the front top of the upper platform.
