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 arc sectors are connected with its vibration horizontal axis, which is located across boat hull. On cradle side sides support wheels are installed in supports with possibility of free rotation on axes rigidly connected with them, and due to cradle center of mass stable orientation to center of Earth, it is located horizontally with possibility of free rolling on support wheels by concave arc guides mounted along boat axis, which vertical axis is connected with its center of mass. Support wheels axes are articulated with electric generators rotors shafts, which secured at cradle.

EFFECT: enabling simplified device to provide boat motion.
