Abstract:

Using an arc driven shock tube facility, measurements of convective heat transfer at the stagnation point of a blunt body were carried out at simulated flight velocities ranging from 20,000 to 40,000 feet per second. These measurements were performed using standard calorimeter techniques with air as the test media. The results indicate no significant ionization effects on aerodynamic heating and indicate that the Lees approximate equation for stagnation point heat transfer can be used for engineering calculations at flight velocities up to 40,000 feet per second.
