The Determination of Drag of a Circulation Control Airfoil Tested in the 7-10-Foot Transonic Wind Tunnel,

Abstract

A special procedure for using the Jones method for determining the profile drag in highly disturbed wake behind a circulation control airfoil is proposed. The procedure suggests that the value of the freestream dynamic pressure be adjusted so that the baseline on the integrand in the Jones method coincides with the zero reference line. Excellent agreement was observed between the results of the new procedure and those of the simultaneous solution values of the Jones and the Squire-Young methods. Additional keywords include: Computations, Equations, Charts, Drag Coefficient.
