Embodiment Construction

[0026] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0027] The most critical idea of ​​this patent is to introduce retractable wings that can rotate horizontally and vertically around the body, and introduce retractable filling and drainage buoys.

[0028] see Figure 1 to Figure 5 , an unmanned submersible aircraft, comprising an air vent 1, a fuselage 2, a retractable wing 3 that can rotate horizontally and vertically around the body, a pair of ailerons 4, a V-shaped tail 5, an air propulsion propeller 6, and an engine 7. Underwater rudder 8, underwater propulsion propeller 9, underwater power motor 10, retractable filling and discharging buoy 11, and operating cylinder 12.

[0029] As can be seen from the above description, the beneficial effects of the present invention are: the retrac...

Abstract

The invention relates to an unmanned underwater aircraft which comprises an aircraft body, retractable aircraft wings, an engine, an advancing propeller, an underwater power motor, an energy storage system, an underwater rudder and a retractable water filling and draining buoy. The unmanned underwater aircraft has the beneficial effects that lift force is provided for flying by unfolding the aircraft wings, the aircraft wings are arranged on the two sides of the aircraft body in a folded mode, the unfolding direction of the aircraft wings is parallel to the axis of the aircraft body, and the sailing resistance is reduced; the buoy is used for water filling and draining so as to adjust the density of the aircraft, so that the aircraft is made to enter or emerge from the water; the water resistance of the aircraft when sliding on the water can be improved by unfolding the buoy, and the resistance can be reduced by folding the buoy; the engine is used for providing power for aerial propelling and charging a storage battery, and the storage battery is used for supplying power to a motor during underwater sailing and driving the underwater advancing propeller; and when the aircraft passes through the water and air media, the engine and the motor are switched accordingly. The unmanned underwater aircraft can meet application requirements in water and air and can be switched repeatedly between the underwater sailing mode and the aerial flying mode.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned submersible aircraft. Through the application of rotatable and retractable wings, retractable filling and drainage buoy technology and two sets of power systems, the aircraft can realize two mediums of water and air. Flying and sailing in the environment. Background technique [0002] As a kind of aircraft that can cross water and air, the submersible aircraft attracted the attention of researchers in the 1930s. However, due to many technical conditions, the development of submersible aircraft was not successful until the end of the 20th century. . In 2008, the U.S. Defense Advanced Research Projects Agency proposed a series of challenging indicators for submersible vehicles, including the ability to fly in the air and submerge in water. From 2008 to 2011, the U.S. Defense Advanced Research Projects Agency extensively solicited feasible solutions for submersible ai...
