Abstract:

A front-lighted photographic system employing a giant-pulse ruby laser as a light source has been developed and installed in the 1000-ft hypervelocity Range G of the von Karman Gas Dynamics Facility. Preliminary results indicate that this photographic technique provides an excellent method for in-flight examinations of model integrity, surface condition, and for accurate in-flight measurements of model profile dimensions plus or minus 0.002 in. and their changes that might be produced by erosion or ablation.
