This study presents a novel propulsion-airframe integrated analysis coupling a validated quasi-one-dimensional flow solver with CFD. It resolves thermal choking limitations in conventional Rayleigh models at high angles of attack or low flight Mach numbers, enabling accurate, efficient prediction of power-on aerodynamics and stability essential for future spaceplane conceptual design.
