To consider compressible transonic effects a vortex lattice method for the computation of the rotor flow is coupled with a field panel method. For this purpose Cartesian grids are used which are not adapted to the contour and only discretise the domain of the nonlinear flow. The basis of this procedures is the separation of the full potential equation into the Laplacian operator and the nonlinear terms. The developed program ROFPM is validated at several test cases of the CARADONNA rotor.
