Rain Impact Assessment of Advanced Thermal Protection System Materials: Phase I Test Results,

Abstract

A rain impact test program, will study the durability of advanced thermal protection system (TPS) materials under exposure to rain conditions typical of flight. Damage threshold levels were bracketed or upper limits established for the rigid TPS materials. The borosilicate glass-coated TPS failed by flexure of the coating, and a rough correlation of rain impact resistance with the compressive modulus of the tile substrate material was found. The durability of the bare tile material was not substantially increased by the use of a SiC coating infiltrated and sintered in the surface layer. The testing technique used with the flexible cloth class of TPS entailed difficulties which precluded the acquisition of valid test data, and alternative approaches for obtaining the desired data are being explored. Keywords: Rain erosion; Rain impact; Thermal protection System (TPS); Aerospace craft; and Tiles.
