Zusammenfassung:Undulating surface, constituted by a series of rigid segments, each one of them driven by two axes, each of which follows a linear oscillatory movement, out of phase with the previous one. In each rigid segment the housing of one of the two axes must be ojalado in order to allow the variation of the wheelbase. The linear oscillatory movement of each of these axes can be obtained by means of motors, magnetic drive or mechanically by means of: cams, crank-crank systems, eccentric systems, etc. It improves the energetic performance with respect to rotating propellers by decreasing the energy lost in vortices of the outgoing fluid. It improves the energy efficiency with respect to the flexible undulating membrane since in this case the motive energy will not be reversed in overcoming the elastic resistance of the membrane.
