Science Applications International Corporation (SAIC) has a contract with the US Department of Energy (DOE) through Sandia National Laboratories to develop a commercial 25 kW{sub e} solar thermal power system using a dish concentrator and a Stirling engine. The program duration is five years, and is divided into three phases. The program is a joint-venture funded equally by DOE and the industry participants, including several utilities. The project goal is to commercialize the technology by the late 1990`s for utility applications in the US and around the world. This paper presents the approach to the development of the solar concentrator. With goals of low cost, low weight, and high performance, the concentrator design has incorporated many unique and innovative concepts. The analysis methodology used in the structural design is described in detail including design criteria, wind load development, and modeling techniques. Procedures for the conversion of structural deformations into optical performance characteristics are also presented.
