BEHAVIOR OF NOZZLE MATERIALS UNDER EXTREME ROCKET MOTOR ENVIRONMENT
Abstract
The program is a research investigation of the behavior of rocket nozzle materials under extreme rocket motor environments. The environments of particular interest are those associated with uncooled nozzle service in advanced or future solid propellant rocket motors. Principal emphasis is placed on graphitic materials, high-melting carbides, and the most refractory metals. Chemical reactions effects of the propellant exhaust environment on these materials are studied as well as thermal and mechanical factors. Methods of reducing or controlling deleterious effects are also of interest. A plasma torch test technique which exposes the bore of a tubular specimen to a high heat flux and a high velocity of selected gas mixtures was conceived and developed.
