A Study of Solid-Propellant Rocket Motor Exposed Materials Behavior

摘要

The objectives of the study: (a) To develop design tools, in the form of digital computer programs, for the nozzle designer to use for calculating the behavior of materials exposed to a solid-propellant rocket-exhaust environment. (b) To marshall existing theoretical methods, or develop new methods, to gain a better understanding of the fundamental mechanisms. Work was directed toward development of two digital-computer programs. One is applicable to materials such as graphite and tungsten, that, erode with one moving boundary or do not erode at all. The other applicable to the reinforced plastic materials that form a char layer. Effort in the areas of transient conduction, equilibrium chemistry, reaction kinetics, and mass transport, as applied to the solid-propellant rocket problem, is described in detail.
