Research on quantitative evaluation method of scramjet and integration

The objective of this paper is to develop a method for the advancement quantitative evaluation of scramjet and hypersonic vehicle/scramjet integration. By studying the theory of analytic hierarchy process (AHP), a new method to build the quantitative evaluation system was established. The theory of Nondimensional parameter was also proposed and the results showed that this calculation method is scientific and effective. Both the numerical simulations of the advancement quantitative evaluation of scramjet and hypersonic vehicle/scramjet integration were carried out with a number of calculation examples and the advancements of different projects were obtained, which proved the feasibility and reliability of the evaluation method. This quantitative evaluation method simples the complex problems of scramjet and integration evaluation and lays the foundation for the further research of hypersonic technology.
