Recent Measurements of Aero-Optical Effects Caused by Subsonic Boundary Layers
نویسندگان
چکیده
Results of recent experimental measurements of aero-optical distortions caused by turbulent boundary layers at subsonic speeds M=0.4..0.6 are presented. Measurements were performed using a high-speed Shack-Hartmann sensor to collect instantaneous wavefronts with high spatial and temporal resolution, accompanied by wavefront measurements with a Malley probe. Effects of different aperture sizes on levels of aero-optical aberrations and detailed statistical analysis of spatial and temporal spectra of aero-optical distortions for both wavefront sensors are presented and discussed.

متن کاملAFRL-OSR-VA-TR-2015-0159 Control of Boundary Layers for Aero-optical Applications
This report presents results of systematic experimental studies of various passive mitigation techniques to reduce aero-optical effects caused be turbulent boundary layers. Parametric studies of Large-Eddy BreakUp devices showed that aero-optical distortions can be suppressed by 45% for several boundary layer thicknesses. It was shown that moderate cooling of the wall also reduces aero-optical ...

متن کاملAero-Optical Measurements in a Turbulent, Subsonic Boundary Layer at Different Elevation Angles
This paper describes a recent investigation of aero-optical properties for subsonic turbulent boundary layers on a flat plate. Laser propagation through the boundary layer at several oblique elevation angles, Mach numbers, and boundary layer displacement thicknesses was investigated. A simple model is proposed that incorporates the oblique angle dependence into an existing scaling relationship....
