SHIPBOARD WAVE-ACTUATED PROPULSION PLANT Russian patent published in 1999 - IPC

FIELD: creation of thrust using energy of sea waves. SUBSTANCE: plant includes wave drive and wave propulsor interconnected by means of parallel link mechanism including horizontal rods and at least one vertical rod connected by means of hinges; two of them are connected with ship's hull; provision is also made for flexible member for locking the rods. Wave drive has wing rigidly secured on vertical rod. Wave propulsor has wing articulated with horizontal rod and spring-loaded relative to it. Arm between axis of turn of this wing and hinged connected with ship's hull is more than arm between vertical rod and above-mentioned hinge. Provision is made for additional drive using energy of shipboard source for turning the horizontal rods in vertical plane. EFFECT: enhanced efficiency of using energy of sea waves through increase of thrust. 2 cl, 1 dwg
