LIFEBOAT WITH HYDRO WAVE PROPULSION DEVICE Russian patent published in 2016 - IPC B63C9/02 B63H19/02 

FIELD: ship building.

SUBSTANCE: invention relates to shipbuilding, in particular, to small floating vehicles, boats and rafts, as well as to their propulsion gears, in particular, to propulsion propeller drive. Lifeboat with hydro wave propulsion device consists of cradle with passengers seats, which has possibility of cyclic oscillations at angle of ±α at boat pitching on waves. Cradle ends are aligned with vertical arc sectors, centers of which are connected with its vibration horizontal axis. Horizontal axis is located across boat hull. For cradle center of mass stable orientation to center of Earth, it is installed horizontally on support wheels with their axes, which have possibility of free rotation in supports installed in boat hull. Supports are arranged along boat axis with cradle arc sectors bases and free roll on support wheels. Cradle center of gravity is aligned with end arc sectors vertical axial cross-section. Support wheels axes of rotation are articulated with electric generators rotors shafts, which are installed in boat hull.

EFFECT: enabling simplified device to provide boat motion.
