Abstract

Engineering of high-precision large deployable antennae is a promising way of space technology. Spacecraft radio system characteristics considerably depend on antenna system dimensions. After a spacecraft reaches a prescribed point in the orbit, load-bearing elements of large space antenna unfurl themselves from compactly folded transport state, stretch the radio reflecting active surface and take the operating position. Mathematical models of space antenna truss reflector deploy are considered. The way allowing estimation of loads acting on rods at the moment of their full deploy is suggested. An attempt of physical modeling (on the basis of similitude theory) for truss antenna unfolding was made. 1 Introduction
