The invention discloses a scheme of a flying lifesaving
system fixedly or movably arranged on the bridge or
deck, characterized in that: a large-
diameter main ducted coaxial reversible dual-rotor body is used for bearing main lift; small-
diameter ducted rotor bodies are symmetrically arranged around the large-
diameter main ducted coaxial reversible dual-rotor body in the same plane, connecting arms can freely move in the forms of stretching, twisting, shaking and swinging, thus the effects of bearing assistant lift, mainly controlling the direction and resisting vortex ring are achieved; and a variable
inertia system and an
energy delivery dragging cable
system are arranged in the main rotor. The device can
resist turbulent flow sudden shearing transition winds and has anti-adverse wind long-endurance submersible capability, can fly within the length of the dragging cable or the distance of
wireless remote like helicopter rescue principles under sea conditions in
bad weather and directly fly beyond the persons in water to hover to conduct marine salvage; and can land on the water surface to float to release rescue devices to let the persons in water enter, and swan the rescue devices by using the motive force of the rotors and the pulling force of the
energy delivery dragging cable to the lifeboats to save people, thus the rescue scheme and equipment of the rescue devices under sea conditions in
bad weather are achieved.
