Paper Abstract

An experimental investigation was undertaken to examine the aero-optic performance of multi- aperture windows for use in hypersonic endo-atmospherical vehicles. A series of imaging tests was conducted through a two-dimensional flat plate model of a multi-aperture window that was incorporated into the Teledyne Brown Dual Nozzle Aero-Optic Simulator (DNAOS). This simulator brought two high-velocity gas streams together in an enclosed test region to form an approximate Mach 2 mixing/shear layer, creating the turbulent properties found in hypersonic flight. The same series of tests was conducted looking through a monolithic flat plate window. The images recorded through both window schemes were analyzed to determine image distortion and results were compared to demonstrate the various optical phenomenon associated with multi-aperture windows.
