Pitching Stability Derivatives of Wing in Supersonic and Hypersonic Flows-Perturbation Method

Using strip theory, an approximate method is developed for predicting the aerodynamic stability of oscillating supersonic/hypersonic wings of arbitrary planform, which uses the unsteady flow solutions of Ref. 1] over an oscillating airfoil with pointed leading edge plus strip theory approximation to obtain the formulas for the stability derivatives.Good agreement is obtained with existing thoeries in various special cases. They are applicable for wings of arbitrary planform shape with pointed leading edge wing section at arbitrary angle of attack provided the shock wave is attached to the leading edge of the wing.
