This literature introduces a reduced-order analytical model for simulating a constant area scramjet isolator operation. The steady modes of isolator operation, namely, shock free mode, oblique shock-train mode and normal shock-train mode are modeled assuming thermally perfect gas flows and using semi-empirical techniques. The analytical model characterizes the flow field for different modes of isolator operation based on physical phenomena observed in the existing literature. The model is developed on MATLAB platform with the flexibility to design the isolator geometry and to set its boundary conditions for the analysis. The reduced-order isolator model is validated with computational and experimental data reported in the existing literatures and found to be in good agreement with them.
