VSTOL ground effects testing with flow visualization and image enhancement
Author and Affiliation:
Kegelman, Jerome T.(McDonnell Douglas Research Laboratories, Saint Louis, MO, United States)
Johns, Albert L.(NASA Lewis Research Center, Cleveland, OH, United States)
Abstract: A remotely controlled high-energy fiber-optic light delivery technique is employed to examine the implementation of a laser-light-sheet flow-visualization system. During testing, video data are enhanced in real time using digital image processing techniques. A summary of test results for an advanced VSTOL configuration in ground effect, and techniques for the generation of 3D reconstructions for the flowfield are outlined. The system performed well during all phases of the test and proved to be an extremely useful asset to the overall test program. The most useful application of the flow visualization system was the interactive real-time flow field analysis made during the actual testing.
