Provided is a reflector that can be developed in an easier way and a developed antenna and an aerospace vehicle that use the reflector. Provided is the reflector comprising: a hub the cross section ofwhich is formed in a circular shape, an elliptical shape or a polygonal shape; a plurality of ribs each of which has an inner surface facing the perimeter of the hub when the rib is folded, each ribalso having an outer surface that is the opposite surface to the inner surface, the plurality of ribs being able to be folded in such a manner that the inner surface of each rib and the outer surfaceof the rib adjacent thereto or the outer surface of each rib and the inner surface of the rib adjacent thereto partially overlap each other and are wound about the perimeter of the hub, the pluralityof ribs being able to be developed, from the terminal end connected to the hub toward the front end located oppositely to the terminal end, into a parabolic shape; and sheet-like bodies that are installed between respective ones of the plurality of ribs and that can reflect radio waves.

    提供能够以更简便的方法展开的反射器、以及使用了该反射器的展开天线和宇宙飞行器。提供反射器,其包含:轮毂,其剖面形成为圆形状、椭圆形状或多边形状;多个肋,它们分别具有在折叠时面向所述轮毂的外周侧的内侧面和作为所述内侧面的相反侧的面的外侧面,并且该多个肋以各肋的内侧面和与各肋相邻的肋的外侧面、或者各肋的外侧面和与各肋相邻的肋的内侧面局部地重合的方式卷绕于所述轮毂的外周而被折叠,从与所述轮毂连接的末端朝向位于该末端的相反侧的前端呈抛物线形状展开;以及面状体,其架设在所述多个肋的各个肋之间,能够反射电波。
