A numerical study was conducted for investigating the thrust performance of an integrated combustor with an ejector rocket, augmenting the thrust of the dual mode ramjet which is one of the main component of a multiple joined combined cycle (MJCC) under the flight Mach number 4 condition. The numerical analysis with a commercial software (FLUENT<SUP>TM</SUP>) was performed with an efficient grid quality by comparing the analysis results. NASA CEA(Chemical Equilibrium Applications) results were applied to the inlet condition of the ejector rocket. The thrust performance of the integrated combustor was investigated with respect to the shape (wedge angle), fuel type (hydrocarbon, methane), operating pressure, and the conditions with and without the ejector rocket.
