Abstract:

An apparatus to generate a wave-like pattern of forces on a surface effect ship utilizes a flexible membrane which undulates in a water wave-like manner, the crests of the waves transferring forces to the surface effect ship. The membrane is undulated in its sine wave configuration by means of a series of linkages, one link of which is pinned to the underside of the membrane. That link is reciprocally actuated and the combined movements of the various linkages cause the membrane to undulate as would water waves. The main drive motor drives a primary shaft to which are connected a series of gear boxes which in turn drive secondary drive shafts. By controlling or varying the speed of the primary drive motor, the frequency of the generated waves may be varied. At each linkage station there is a crank and the connecting rod is adjustably connected to the crank. The amplitude of the waves can be varied as desired by adjustably positioning the connecting rod along the crank.
