Abstract: Static- and forced oscillation tests with a ground effect machine model were performed (in cooperation with the Shipbuilding Laboratory – Delft) above ground without forward velocity and above water with forward velocity. The main object of the investigations was to study the use of this experimental method for ground effect machine models. The coefficients of the equations of motion could be determined from the results of the tests. The flying height and trim angle in the equilibrium motion were calculated from the static coefficients. The dynamic stability roots, the natural frequencies and damping ratios of the model were obtained by solving the homogeneous equations of motion.
