FURTHER DEVELOPMENT OF AN INDUCTANCE-DRIVEN HOTSHOT TUNNEL
Abstract
The development and evaluation of arc chambers for the inductance-driven tunnel Hotshot 2 is described. A coaxial electrode arc chamber configuration was developed which, when used with a nine millisecond arc discharge time, resulted in a further significant decrease in flow contamination. Drag measurements on slender models with this arc chamber were in substantial agreement with drag measurements carried out in other tunnels in the Mach number range from 16 to 22. Measurements of stagnation point heat transfer rate improved as contamination was reduced, but the consistency of the measurements was not satisfactory. All tests described herein were carried out with nitrogen at stagnation temperatures from 3000 to 4000 K and stagnation pressures from 10,000 to 20,000 psi. (Author)
