PURPOSE:To eliminate the need to perform precise mechanical control for the formation of parabolic surfaces by adhering two thin-film parabolic surfaces to an annular dividable frame member, folding them before launching, and injecting a small amount of gas in space. CONSTITUTION:A parabolic surface 4 made of a thin metallic film and a parabolic surface 5 made of a thin nonmetallic film adhered to the left and right sides of the annular dividable member 3 are folded when a rocket is launched. While a feed horn 1 is extended in space, gas is injected from a gas intake 2 to form a parabolic curved surface body symmetrical about a vertical line, thereby forming the extended parabolic surface without mechanical control. |
