Abstract

The Infrared Space Observatory (ISO) is a satellite which will investigate deep space by receiving infrared radiation from distant objects. Sunshade Support - the payload module element is achieved by the use of 16 tubular struts forming a continuous triangular arrangement around the upper area of the spacecrafts cryostat vacuum vessel. There are two prime requirements for the struts, namely: * to transfer the flight loads of the Sunshade into the cryostat vacuum vessel structure whilst maintaining the Sunshields correct orientation, and * to provide thermal isolation between the cryostat vacuum vessel and the Sunshade Composite struts and in particular their end terminations and manufacture have long been an engineering problem. The solution proposed in this paper is considered to have of reach
