Abstract The aim of this paper is to present an aerodynamic analysis of the N1G missile geometry at supersonic and hypersonic Mach numbers to understand how the behaviour varies as it transits from the supersonic to the hypersonic flow regime. The study contemplates to provide new insights into the missile aerodynamic performance which includes lift and drag coefficients using computational fluid dynamics (CFD). The first part of the study involves the validation of the results from the computational simulations with the experimental data available from the wind tunnel tests. This validation establishes the accuracy and robustness of the numerical method. The research further extends to analyze the aerodynamic performance in the supersonic and hypersonic regime, for the same missile geometry. The paper intends to feature the differences in the aerodynamics of the missile as it goes beyond the supersonic threshold. Variations in the flow pattern, shock wave and aerodynamic forces (lift and drag) were observed and discussed. This work will impart a valuable analysis of the complex flow phenomena which is associated with the hypersonic regime, providing necessary data for the optimization of the geometry. The study also lays the groundwork for better computational models, which are essential for developments in missile technology and other aerospace applications that operate in the hypersonic regime.
