American Institute of Aeronautics and Astronautics 1 Preliminary study of a roughness-induced boundary-layer transition experiment in a Mach 6 Ludwieg tube 2d Lt Thomas B. Gil French Air Force Academy, 13300 Salon-de-Provence, France The US Air Force Academy Department of Aeronautics is willing to collect data on the influence of surface roughness on the boundary-layer transition on blunt bodies, which can later be used for further guidance in the design of space capsules for NASA exploration missions. This requires that we understand how the boundary layer performs at hypersonic speeds, and that we analyze its behavior around blunt bodies with different workable and observable surface roughnesses in a hypersonic wind tunnel. Since September 2012, several cadets worked on the hypersonic Ludwieg Tube in the Department of Aeronautics at the US Air Force Academy, did flow simulations, observed and analyzed the behavior of the flow with blunt objects in the test section. This fall, a data
