Description:
The general design and operating conditions of NASA Ames's electric arc drive shock tube facility are described, and the measurements conducted at the facility to support the development of a theoretical model of the effects of chemical nonequilibrium over a hypersonic vehicle are summarized. In particular, attention is given to the results of measurements at a shock velocity of 6.20 km/s in 1 Torr nitrogen and measurements at a shock velocity of 10.2 km/s in 0.1 Torr air. The discussion covers reaction rate measurement, the use of holographic interferometry, and measurements of vibrational populations using Raman scattering.
