Abstract
PURPOSE:To reduce the vibration by approaching horizontal oscillation blades of an aircraft wing form in the longitudinal direction, arranging doubly, and swaying up and down the both blades at the phase difference 180 deg. in the reverse directions by a double crank device, in the captioned device for vessels. CONSTITUTION:By rotating a power crankshaft 9 in the arrow 26 direction, a front oscillation blade 16 and a rear oscillation blade 21 are moved swaying in the reverse directions in order to generate a propulsion force. Since the both blades 16 and 21 sway at the phase difference 180 deg., the moving amount in the up and down direction of the both blades can be made equal by making the weight sand the blade areas of the both blades 16 and 21 equal. Consequently, the inertia forces and the fluid forces of the both blades 16 and 21 are set off and balanced, and the vibration can be reduced.
