Abstract:

Two relatively new measurement techniques have been found to be useful in shock tunnel experimental studies. These techniques as they have been employed in the General Electric MSVD shock tunnel are described. A light-weight cast Isofoam, generally from 1 to 5 grams in weight model is suspended in the shock tunnel test section on thin .5 - 1.5 mils nylon strands. The strands break at the beginning of the test flow, and the model flies freely under the influence of the aerodynamic forces it experiences. The second shock tunnel experimental technique involves the generation of oil streak patterns on the surface of bodies subjected to the test flow. Such data are useful in heat transfer studies and in developing an understanding of complex three dimensional flows.
