The invention, which belongs to the technical field of spacecrafts, discloses a large-diameter lining-free composite material storage tank connecting structure comprising an inner flange part and an outer flange part. The inner flange part is provided with an inner flange cylinder; the bottom face of the inner flange cylinder extends outwards and obliquely downwards to form an inner annular flange, inner flange outer threads are arranged on the outer side of the inner flange cylinder, an outer flange cylinder matching the inner flange cylinder is arranged on the outer side of the inner flange,a sealing groove is formed in the top side of the outer flange cylinder, the top face of the outer flange cylinder extends outwards to form an outer annular flange, and a through hole is formed in the outer annular flange. The forming process of the aluminum alloy flange connecting structure is simple and convenient in requirement; and after the storage tank using the connecting structure is wound and formed, the structure is safe, the sealing performance is good, and the weight reduction effect of the storage tank is obvious by being compared with metal storage tanks of the same specification.
本发明公开了一种大直径无内衬复合材料贮箱连接结构,属于航天器技术领域。本发明包括内法兰部分和外法兰部分,内法兰部分设有内法兰筒体,内法兰筒体底面向外侧斜下方延伸形成内环形法兰,内法兰筒体外侧设有内法兰外螺纹,内法兰外侧设有外法兰筒体与内法兰筒体配合设置,外法兰筒体顶侧设有密封槽,外法兰筒体顶面向外延形成外环形法兰,外环形法兰上设有通孔。本发明中铝合金法兰连接结构的成型工艺要求简便,应用本发明的贮箱缠绕成型后,结构安全,密封良好,较同种规格的金属贮箱减重效果明显。
