Abstract

The Starlab telescope's design approach used extensive nonlinear FEM analyses of the suspension systems and primary mirror/bonded assemblies in order to achieve the requisite optical sensitivity to attachment system-induced forces, in combination with the distribution of launch loads through thin sections from concentrated attachment points. A test program verified all aspects of the design. Attention is presently given to the design principle used, involving the splitting of the suspension system's functionality.
