The invention relates to a spaceflight launching device, in particular to a guide rail which is made of glass fiber reinforced phenolic resin matrix composites and comprises a first guide rail assembly, a second guide rail assembly and a third guide rail assembly. The two sides, in the width direction, of the second guide rail assembly are connected with one side edge, in the width direction, of the first guide rail assembly and one side edge, in the width direction, of the third guide rail assembly correspondingly, the surface of the first guide rail assembly is a first bearing face, the bottom face of the first guide rail assembly is a first connecting face, and the first bearing face is an arc face. The surface of the second guide rail assembly is a second bearing face, the bottom face of the second guide rail assembly is a second connecting face, the second bearing face is an arc face, and the second bearing face and the first bearing face are symmetrical relative to the second guide rail assembly. The guide rail is light in weight, high in strength, low in cost, excellent in bearing function and thermal ablation resistance and capable of being repeatedly used.

    本发明涉及一种航天发射装置,特别是涉及一种导轨,所述导轨由玻璃纤维增强酚醛树脂基复合材料制成,本发明导轨包括第一导轨组件、第二导轨组件、第三导轨组件,所述第二导轨组件沿宽度方向的两侧分别与所述第一导轨组件沿宽度方向的一侧边及所述第三导轨组件沿宽度方向的一侧边相连接,所述第一导轨组件的表面为第一承载面、底面为第一连接面,所述第一承载面为弧面,所述第二导轨组件的表面为第二承载面、底面为第二连接面,所述第二承载面为弧面,所述第二承载面与所述第一承载面相对所述第二导轨组件对称。本发明导轨重量轻、强度高、成本低,并且承载功能和抗热烧蚀性能优良,可重复使用。
