Overview of the Skin Friction measurements on the NASA BeVERLI Hill using Oil Film Interferometry
Viscous drag reduction plays a vital role in increasing the performance of vehicles. However, there are only so many measurement techniques that can quickly and accurately measure this when compared to pressure drag measurement techniques. The current study makes use of one of the direct and robust …

Experimental investigation into the reduction of supersonic skin-friction drag on a flat plate using transpiration and a cavity with mass addition
… evaluation of an operational facility for wall drag measurement and evaluation of the total drag of various wall configurations. The drag of three possible supersonic combustor wall configurations was measured to determine if reduction in skin friction and/or wave drag could be achieved through …

Design and Validation of a Force Measurement System for the Analysis of Airfoil Lift and Drag Characteristics
… the flow separation and therefore the pressure drag generated by a wing section, through the adding of surface modifications. The modifications consisted of roughening the surface of polystyrene airfoils using a sand blasting technique, which resulted in a dimpled surface. This idea originated …

Drag Measurements on an Ellipsoidal Body
A drag study was conducted on an oblate ellipsoid body in the Virginia Tech Stability Wind Tunnel. Two-dimensional wake surveys were taken with a seven-hole probe and an integral momentum method was applied to the results to calculate the drag on the body. Several different model configurations …
