Radiation and Scattering of EM Waves in Large Plasmas Around Objects in Hypersonic Flight Open
Hypersonic flight regime is conventionally defined for Mach larger than 5; in these conditions, the flying object becomes enveloped in a plasma. This plasma is densest in thin surface layers, but in typical situations of interest it impact…

Pitch damping identification in high speed regimes with a free-to-tumble rig Open
Many re-entry bodies, even if they are debris or not, have nonlinear dynamic stability characteristics that produce oscillations in flight. The free-to-tumble techniques can be used to extract damping coefficient of specific body for plane…
