Abstract
This paper concerns the aerothermodynamics of high–speed gas flows around the EXPERT reentry flight vehicle moving at different angles of attack at an altitude of 50 km with the speed V∞ = 5 km/s. Calculations were carried out using UST3D and UG3D computer codes developed at the Ishlinsky Institute for Problems in Mechanics RAS (IPMech RAS). The computer codes implement the numerical simulation of the flight vehicle aerothermodynamics by integrating the complete set of Navier–Stokes equations on unstructured mesh using the ideal gas model.
