A vessel propelled and raised by air propellers

Abstract

A ship with an air propeller for propelling and hovering a ship body comprises the ship body and an air propeller power device installed on a deck of the ship body. A flow collecting nest is arranged right behind the air propeller power device. The side, facing the air propeller in the air propeller power device, of the flow collecting nest is open, and the opening area of the flow collecting nest overlaps the rotation diameter internal area of the air propeller in the air propeller power device. The part, below the deck, of the ship body is provided with a sealed flow guide air passage, the bottom of the ship body is provided with a hovering channel, the bottom and the tail of the hovering channel are open, and the tail opening of the hovering channel is provided with a movable door capable of being opened and closed. An air outlet of the flow collecting nest communicates with the flow guide air passage, the communicating positions of the air outlet of the flow collecting nest and the flow guide air passage are connected in a sealed mode, and the flow guide air passage is provided with an air outlet hole communicating with the hovering channel. According to the ship with the air propeller for propelling and hovering the ship body, the functions of propelling and hovering can be achieved by means of the air propeller, development of small hovercraft is facilitated, and the amphibious applicability of the ship is improved by adjusting the hovering function.

Description

technical field [0001] The invention relates to the technical field of air-propelled ships, in particular to an air-propelled ship that uses an air propeller to simultaneously realize the functions of propulsion and lift. Background technique [0002] In order to meet the requirements of amphibious performance, ships using air propeller engines as power systems have been born, which are generally called air-propelled ships, the most typical of which is the hovercraft. Existing full lift or small hovercraft generally use lift fans and air propeller propellers to complete lift and propulsion tasks respectively. They have amphibious capabilities and can be used in water and land transition areas such as swamps, tidal flats or beaches. In order to make the hull not in contact with the surface, the existing hovercraft must use pad lift fans to continuously replenish the air supply in the air layer formed between the flexible apron structure of the hull and the surface. The pad-l...

AI Technical Summary

Problems solved by technology

Since the hovercraft needs to lift the entire hull off the surface with a lift fan, the power of the lift fan is very large, and the size and weight of the corresponding lift fan are also very large, which greatly limits the development of small hovercraft.
