摘要

ESA's Atmospheric Reentry Demonstrator is Europe's first complete space re-entry mission. The mission involved launching a vehicle into space by the Ariane-5 launcher and its safe recovery form the Pacific Ocean. A description of the ARD and its mission is given in Section 1. The usual methodology for extrapolation to flight has been implemented, by anchoring the start of hypersonic regime on the classical "cold" hypersonic wind tunnel test results. ARD's aerodynamic and aerothermodynamic pre-flight values, were interpolated between ONERA S4 Mach 10 data and Apollo Mach 30 flight data to the ARD. After the description of the ARD and its mission, the results of the S4 wind tunnel tests will be compared to numerical simulations in Section 2. The S4 pre-flight measurements provide aerodynamic pitching moments versus angle of attack as well as pressure and heat flux measurements.
