Abstract:

Evaluations and remedial modifications to laser photography systems have resulted in a 30-percent increase in reliability for optimum performance. Another unique modification to the laser photographic technique has added the capability for flow visualization when desired. A 70-percent increase in spatial resulution has resulted from refinements to photopyrometry systems. Investigations of schlieren-related flow visualization techniques resulted in the selection of a focused shadowgraph arrangement for detection of boundary- layer transition on conical models. Preliminary designs for photographic instrumentation systems for use during erosion testing were completed.
