Abstract

Renewed interest in hypersonic flight has generated a requirement to validate optical sensor performance in the hypersonic environment. In this paper, the flight aero-optic environment is examined and the mixing layer is determined to be the largest aero-optic contributor. The paper then examines how this mixing layer can be reproduced in a ground test facility. Teledyne Brown has developed and constructed a compact hypersonic aero-optic simulator which properly scales the mixing layer. This small simulator is designed to emulate the significant aero-optic features of the hypersonic window coolant mixing layer present in current interceptor designs. Through careful selection of gas supply conditions and species, this experiment is capable of reproducing the most significant aero-optic effects of the flight environment.
