The space ship antenna reflector null which in order to fold up in the container of the capacity which is restricted is simplified

摘要

PURPOSE: To obtain a method of folding an antenna reflector, used for a spacecraft into a package with a limited volume and of expanding the reflector from the package when in use. ;CONSTITUTION: This antenna reflector 10 is made of integrated flexible materials having a predetermined creep distortion limit, a deformation force within the creep distortion limit is exerted to positions 16, 18 of the reflector around the Edges of the reflector opposite to each other diametrically in the reflector, to keep the reflector 10 in a deformed state by means of a string 20 until the reflector 10 is expanded. Then the string 20 is loosened to release the reflector 10 from the deformed state and to restore the reflector to the original state.;COPYRIGHT: (C)1993,JPO
