HipeX is a fast and lightweight aerothermodynamic analysis tool developed to estimate aerodynamic coefficients and surface heat fluxes on hypersonic vehicles using local surface inclination methods. The solver combines classical techniques such as the tangent-wedge method, the modified Newtonian approach, and Prandtl–Meyer expansions to evaluate pressure distributions across arbitrary geometries. Heat flux predictions are derived using similarity-based boundary-layer models, with compressibility effects accounted for through Eckert’s reference temperature formulation. A key feature of HipeX is its blended boundary-layer model, which transitions from laminar to turbulent flow based on local Reynolds number. Validation against benchmark CFD data for the HEXAFLY-INT experimental configuration shows that HipeX provides reliable aerodynamic and thermal load estimates.
