Abstract

The invention provides a single-rotor sea-air craft, which can adjust the angles of four rudder plates at will through a motor, realize different working condition adjustment in different mediums, and has the advantages of air flight, underwater diving, water-air medium conversion capability and strong maneuverability. The invention can regulate the propelling force by controlling the rotating speed of the four pump jet propellers, and has higher flexibility by matching with four rudder plate mechanisms which can be regulated at will. The invention is very suitable for underwater diving, can realize underwater rapid diving by using the pump jet propeller, realizes deeper water work and enlarges the operation range. The diameter of the propeller is similar to the total length of the airplane body, and the ratio can fully utilize the gain of the near-surface effect, so that additional lift force is provided. When the energy-saving guide wheel is moved in water, the propeller freely rotates by utilizing wake flow generated by the movement of the aircraft, thereby playing a role of the energy-saving guide wheel and saving energy consumption.
