The prediction of the on-ground risk caused by re-entering space debris requires accurate and computationally affordable models to compute wall heat flux and pressure coefficient C p at every stage of the reentry. Such models already exist for the wi

International audience; Following the reentry of the Intermediate eXperimental Vehicle in 2015, a lot of efforts were carried out at the ONERA for the post-flight analysis and the reconstruction of the heat flux applied to the vehicle. This flight re

Since 1957, more than 27,000 tons of space debris have reentered Earth atmosphere. It is estimated that 10 to 40% of this mass reached the ground, which represents more than 2,700 tons of debris and poses a real threat to goods and persons. Estimatin
