For successive space vehicle missions, the prediction of aerothermodynamics is essential. Aerodynamic data plays a crucial role in trajectory simulation, performance analysis, the design of stability and control systems, as well as the calculation of aerothermodynamic loading distribution. We have developed two methods to estimate aerothermodynamic data: the Engineering or Component Build Up (CBM) method and the Computational Fluid Dynamics (CFD) method. We have extensively addressed various flow regimes, spanning from subsonic to hypersonic, aligning with the demands of space missions. Furthermore, we have curated a comprehensive aerodynamic and thermodynamic database corresponding to these regimes.
