AERODYNAMIC COEFFICIENTS FOR AN OSCILLATING AIRFOIL WITH HINGED FLAP, WITH TABLES FOR A MACH NUMBER OF 0.7

摘要

Dietze's method for the solution of Possio's integral equation has been used to determine the chordwise distribution of lift on an oscil-lating airfoil with simple hinged flap in two-dimensional compressible flow (subsonic). The results of these calculations have been used to prepare tables of aerodynamic coefficients for lift, pitching moment (referred to quarter-chord point), and flap hinge moment for a Mach number of 0.7; the motions considered are vertical translation, airfoil rotation about the quarter-chord point., and rotation of the flap about its hinge line.
