Aiming to realize the optimal design and automatic forming of the conical composite oblique grid structure，the differential geometry method was applied，and combined with engineering applications，a comparative design was carried out on the conical composite oblique grid structures with equal-pitch spiral ribs，equal-helix-angle spiral ribs and geodesic spiral ribs that were easy for automatic forming，and a skinless conical composite hybrid triangular grid satellite support was designed.The corresponding relationship between two types of geodesics was given，thereby simplifying process and reducing costs.Aiming at the problem that the equal-thickness winding of the skin could not be achieved by the equal-pitch spiral trajectory，equal-helix-angle spiral trajectory and geodesic trajectory，a winding forming scheme combining the dense spiral trajectory on the conical surface as the main part with the geodesic trajectory was proposed to realize the automatic laying of the skin with equal thickness for the conical composite oblique grid structure.The conical composite oblique grid structure has met the design and production conditions，and process forming tests can be carried out in combination with engineering applications.Different forms of composite grid structures can be optimized for different application scenarios to ultimately achieve the optimal application effect.
