Abstract
A design method for a thermal control film advantageously used in cosmic space, especially for a multilayer film, includes: setting at least two candidate materials for forming the multilayer film and the number of layers of the multilayer film; and designing a combination of the candidate material and a layer thickness by using a genetic algorithm stored in a computer-readable medium using an evaluation function, and recording the obtained results on a computer-readable medium. The evaluation function includes: αs=1−Rs, wherein Rs represents a reflectance of solar energy in a wavelength range used for design, within a solar radiation wavelength range; and ∈H: ∈H=1−R, wherein Rrepresents a reflectance of heat radiation energy in a wavelength range used for design, within a heat radiation wavelength range.
