Design, Fabrication, and Structural Testing of a Lightweight Shadow Shield for Deep-Space Application.
Abstract
Two 3. 05-meter-diameter (10-ft-diam), full-scale, lightweight, double-sheeted shadow shields were developed as the primary element of a deep-space thermal protection system for liquid-hydrogen propellant tankage. The thermal and mechanical considerations used in the design of the shields, the method of fabrication, and the environmental testing results on a prototype shield are discussed. Testing consisted of a transient cooldown period, a prolonged cold soak, and a transient warmup. The results of the tests demonstrated that the mechanical and thermal analyses used in the shield design are sufficient to produce a lightweight (i. e., 8. 3 kg (18. 2 lb)), rugged shadow shield assembly that is structurally adequate for its intended application.
