MATERIALS FOR RAMJET ENGINES AND COMPONENTS

Abstract

A study was made of materials for ramjet engines and components. The problem was divided into 2 areas: (1) an evaluation of the mechanical properties of conventional aircraft and missile materials when used for more severe boundary conditions, and (2) a search for new materials which can be used in areas in which conventional materials are inadequate. The nature of the materials problem is considered to be a function of temperature and time. A discussion is presented on the effects of temperature and load as a function of time, on the mechanical and physical properties of materials. Some of the properties include average yield stress, modulus of elasticity, resistance to fatigue, tensile strength, thermal expansion and conductivity, ductility, erosion resistance, and elongation. Some of the advantages and disadvantages of currently available and potentially available materials are given.
