PURPOSE:To accommodate easily and expansion type parabolic antenna reflection mirror within a fairing of a rocket by dividing the expansion type parabolic antenna reflection mirror used at a frequency band being a microwave band or over with a few dividing number and also adopting the stack system. CONSTITUTION:Said reflection mirror is divided into components 1,2...6 and two symmetrical components 1, 2 are divided by a bisector L1 passing through the center of the reflection mirror. In folding the reflection mirror, locks 18, 19 are loosened, the components 3, 4 are folded on the component 1 and the components 5, 6 are folded on the component 2. Then the components 1, 2 are folded so as to clip the components 3...6 and fixed by a clamp. The expansion is conducted by releasing the clamp, moving a link mechanism 21 by a pulse motor 20 and expanding the components 1, 2 around the bisector L1. Then the components 3...6 are expanded along a straight line L2 and fixed finally by the lock mechanisms 18, 19. |
