Scientific paper

In order to evaluate the possibility of improving upon an existing aeroshell design for the multi-hundred watt power source, a tradeoff study was conducted on a variety of candidate aeroshell materials. Mariner Jupiter/Saturn mission requirements and aeroshell material criteria were established to form a basis for the evaluation. Material data searches and reentry analyses were made to permit preparation of a quantitative comparision matrix. Depending upon the designer's constraints, either the polycrystalline graphites (POCO-AXF-5Q, ATJS) or the more complex composite materials (AVCO 3D C/C, Pyrocarb-406) may be chosen.
