Measurements of Turbulent Skin Friction on a Flat Plate at Transonic Speeds

Abstract

The present report describes the design and construction of a floating-element skin-friction balance. This instrument, which is essentially an improved version of Dhawan's balance, was applied to measurements of local skin friction in the turbulent boundary layer of a smooth flat plate at high-subsonic Mach numbers and supersonic Mach numbers up to 1.75. The measured skin-friction coefficients are consistent with the results of other investigations at subsonic and also at supersonic speeds. The principal difficulties which exist in comparing skin-friction coefficients at various Mach numbers are discussed.
