The evaluation of the wall heat flux in hypersonic regime is crucial for the design of any space vehicle
and mission. To quickly estimate the wall heat flux during vehicle pre-design phase, surrogate models
are mandatory. The aim of the present work is to evaluate the strengths and weaknesses of the current
models and to develop a general and efficient formulation, i.e. able to quickly obtain accurate results
for any object shape. Hence, a numerical database including a large variety of space objects (gliding
vehicles, capsules, space debris) has been built and analyzed. A new surrogate model has been then
developed and successfully validated by comparison with CFD results.
