abstract = "Variable geometry combustor technology is one of the effective ways to improve the performance of Rocket-based combined cycle (RBCC) engines. Numerical simulation was used to study the performance variation of the variable geometry RBCC combustor for Ma4 flow. The conclusions are as follows: (1) In the Ma4 flow, as the geometric throat height increases, the thrust of the combustor first increases and then decreases. The optimal condition shows a 30\% improvement in performance compared to the minimum thrust condition. (2) Increasing the height of the geometric throat will decrease the pressure in the combustor, causing the shock train in the isolator section to move downstream of the combustor. (3) The area of the geometric throat has an impact on both the combustion and flow within the combustor. This study reveals the mechanism of the effect of the geometric throat on the thrust of the combustor.",
