Paper Abstract

The oil-film interferometry skin friction technique is described and applied to subsonic and supersonic flows. The details for applying the technique are discussed. Results are shown for tests that illustrate the oil-film's good ability to measure the skin friction in a large scale. It is anticipated that continued development of this program will be necessary for use of oil-film technique to become widespread.
