EXPERIMENTAL INVESTIGATION OF AERODYNAMIC FORCES AND SHOCK WAVES FOR A WAVERIDER IN SUPERSONIC AND SLIP REGIME CARRIED OUT IN THE MARHY FACILITY
Résumé
Hypersonic vehicles are more and more studied in the military domain but also for other missions as the interplanetary or commercial missions. These vehicles optimize the ratio between lift and drag forces to success their missions. Hypersonic vehicles studied are launched at high altitude by rockets and they realize a re-entry by changing their angle of attack in function of speed and altitude. In this study, aerodynamic forces (drag and lift) are experimentally measured for different angles of attack and for four different rarefied flows conditions representative of altitudes ranging between 50 km and 80 km. The first part focus on aerodynamic forces and the behavior of the vehicle at altitudes higher than the initial optimal one which is 50 km in this case. The second part consists to study the shock angles at same angles of attack and rarefied flows to correlate shock wave angles and aerodynamic forces.
