Abstract

The growing need for computational codes to optimize windowed hypersonic vehicle designs has required a more complete understanding of aero-optical effects produced in the flight environment. Teledyne Brown Engineering (TBE) has determined the mixing/shear layer created by the cooling of a window on a hypersonic vehicle to be one of the largest contributors to aero-optical distortion. A novel experimental setup is currently being developed that effectively reproduces this mixing/shear layer and thus its significant aero-optical effects. In addition, various test techniques have been devised to investigate these phenomenon, as well as to produce simulated flight data required for validation of the aero-optic optimizing codes.
