ものである。In other words, in the case of space applications, the condensing curved surface structure and truss structure are complex, and the construction cost and construction period are long, although labor and labor savings are particularly required. Especially in the case of a large structure, the capacity of the transportation means (weight and volume,
In the case of the Space Shuttle, it is limited by 4mφ x 18m), and the launch cost is high. Furthermore, there are few examples that take advantage of the weightless environment characteristics of space. Furthermore, since the conventional condensing curved surface structure is a rigid structure, the shape of the condensing curved surface cannot be controlled. Therefore, for example, when the light condensing part is used for melting materials, etc., a shutter is required to block solar heat when not in use. (A shutter is not necessary if the shape can be controlled.) [Means for solving the problem] In order to solve the above-mentioned problem, the present invention is made of a flexible thin film material and has a concave surface formed in a part. An airtight bag having a gas inlet and outlet, a heat collecting part provided facing a concave surface of the airtight bag, and an actuator structure member for controlling the shape of the concave surface and the relative position of the heat collecting part with respect to the concave surface. This paper proposes a solar heat concentrator that is characterized by the following features.
