A STUDY OF SOLID-PROPELLANT ROCKET MOTOR EXPOSED MATERIALS BEHAVIOR
Abstract
A study was made to characterize many of the complex individual phenomena occurring in the ablation process of solid-propellant rocket wall materials. Techniques are used to gain a better understanding of ablation phenomena under simplified conditions and to guide, to a certain extent, the design of aft-closures and nozzles. Theoretical studies were conducted with materials that erode with one ''moving boundary'' such as graphite (nonablating refractories are a special case of this category), and with materials such as the reinforced plastics, or composites, whose ablation can be characterized by two moving boundaries. Experimental studies consisting of graphite and composite-nozzle ablation tests and metallic-oxide particle- impaction tests were carried out. The theoretical effort also included the following areas: convective heat transfer, thermal behavior of a nonmelting, noncharring nozzle insert, nozzle wall chemical erosion, and reaction kinetics.
