A boundary element method is presented for determining aerodynamic loadings on arbitrary configurations in oscillatory subsonic flow. Formulas (modified Morino's method) are given for the unsteady pressure distributions or unsteady force experienced in subsonic flow by the wing-store combination, oscillating in the torsional oscillations about a fixed axis parallel to the span and other oscillating modes (flapping, plunging). Interference effects from an underwing pylon store were analyzed. The method is finally verified through comparison with experiment for the model at angles of attack from -5 degree to +5 degree, and reduced frequencies from 0.65 to l.3 at low subsonic flow.
