Waveriders are a concept of hypersonic lifting vehicles designed to generate an attached bow shock at its
leading edge. Even though this concept is a very active research topic, very little experimental campaigns
were conducted, especially to assess viscous influence on waverider performance. To compensate for
this lack of experimental data, CNRS/ICARE performed an experimental investigation of the aerodynamic
performances of waveriders in rarefied supersonic flows, with Mach numbers ranging from to 2 to 4 and
Knudsen number from 8.3 x 10-5 to 2.1 x 10-3. In the present study, these experimental data are
compared with numerical results of simulations performed with a Navier-Stokes, a discrete-ordinate
ES-BGK and a DSMC solvers for validation purpose. These numerical computations are then used to
complement the experimental observations.
