Summary
A field panel method is described for calculating unsteady transonic perturbation flows about harmonically oscillating wings. The flow is modelled by dipole distributions on the mean wing and wake surfaces and a source distribution in the flow field to account for the nonhomogeneous compressibility effects in the near field of the wing. The aerodynamic influence coefficients can be calculated largely analytically and the resulting system of equations is solved by a quickly converging block iteration. Coupling with finite difference methods can further increase the computation speed.
