The Aerodynamic Behavior of a Harmonically Oscillating Finite Sweptback Wing in Supersonic Flow

Abstract

By an extension of Evvard's "diaphragm" concept outside the wing tip, the present paper presents two approximate methods for calculating the aerodynamic behavior of harmonically oscillating, sweptback finite wings with both supersonic leading and trailing edges. Both methods are based upon the fact that the contribution of the so-called "diaphragm" on the potential at a fixed point on the wing is approximately canceled by the contribution of a portion of the wing itself, if the wing undergoes steady harmonic oscillation at a low value of the frequency parameter.
