In the present study the influence of different fidelity flow solver and structure models on the aerothermodynamic heating of reentry vehicles is investigated. The study is carried out on a generic waverider (WR) geometry. The heating of the structure of the reentry vehicle is determined by a high-fidelity uRANS coupled multidisciplinary analysis. The analysis is performed for the forced flight along a reference trajectory. The coupled calculation leads to a realistic evaluation of the overall heating for the vehicle entering the atmosphere of the Earth. For low-fidelity comparison, fast engineering methods for the flow solution, like the Fay-Riddell formula or the reference enthalpy method, and a structural one-dimensional heat conduction solver are implemented. The differences between models of different fidelity are shown.
