An analysis is presented of current solar concentrator types when integrated into complete space power systems with various electrical conversion methods. Concentrator designs such as inflatable-rigidized, petal, one-piece, and Fresnel are treated in the paper and their size, weight, and packaging characteristics, when combined with dynamic and static conversion schemes, are illustrated. Information presented in the paper provides insight into the selection of concentrator designs for space power applications.

The conflicting demands of packaging, performance, refinement and durability that are currently being placed on automotive valve trains require a hierarchy of methods if their design and development are to be accomplished efficiently. This paper describes these analytical and experimental tools and their use. The tools range from relatively simple methods for rapid design iterations to sophisticated dynamic models of the valve train and timing drive.
