This study investigates the supersonic ground effect aerodynamics of a slender body, focusing on the interaction between reflected shock waves and the body. Preliminary numerical results show that decreasing flight height significantly alters aerodynamic coefficients, with shock waves impacting the lower surface and diffracting onto the upper surface, changing pressure distribution.
