Abstract

A wing mounted flow visualization instrument for use in measuring in-flight aerodynamic parameters that are a critical influence in the performance of modern aircraft is described. These parameters include shock waves, vortices, and the location of boundary layer transitions. The instrument incorporates a rapidly scanned sheet of laser light projected from a pod which illuminates the flow region of interest. The instrument can be rugged, compact, light weight, versatile, operate from available aircraft power, and be easily integrated with existing test aircraft. Flow field data is extracted from the light scattered from the scanning laser sheet by aerosols in the flow field, and from light scattered by the aircraft surface. The results of an analytical study are presented based upon an idealized F-15 configuration which confirms that current laser and camera technology can elucidate and record aerodynamic structures of interest to researchers and engineers.
