Cross-medium unmanned aerial vehicle device and control method thereof

Abstract

The invention discloses a cross-medium unmanned aerial vehicle device and a control method thereof. The cross-medium unmanned aerial vehicle device comprises a shell and a piston which is arranged in the shell and can reciprocate in the shell, one end of the shell is open, and a plurality of flying wings are evenly arranged in the circumferential direction of the piston; the flying wings are rotatably connected to one side, facing the opening, of the piston and are unfolded or folded in an umbrella shape; and under the pushing of the piston, the flying wings can be unfolded towards the outside of the shell and can be folded back into the shell. The piston capable of moving is arranged in the shell, the piston is rotatably connected with the flying wings, the flying wings can be unfolded towards the outside of the shell under the pushing action of the piston and can be folded in the shell, and therefore conversion of different forms in water and air can be completed; when the device enters and moves out of water, the flying wings are folded in the shell and protected by the shell to be prevented from being damaged; and during flying, the flying wings can be smoothly unfolded to guarantee the flying state.

Description

technical field [0001] The invention relates to the technical field of cross-medium operating devices, in particular to a cross-medium unmanned aerial vehicle device and a control method thereof. Background technique [0002] In recent years, aircraft and submarines have developed rapidly, and the performance of various types of aircraft flying in the air has become more and more excellent and perfect, and the diving performance of submarines has also continued to develop and improve. These two machines only sail in a single medium. At this time, people wonder whether it is possible to combine the air flight capability of the aircraft and the diving navigation capability of the submarine to create a new concept aircraft that crosses the two media of water and air, that is, the cross-water-air Two-medium aircraft. This aircraft is a combination of a submarine and an aircraft. It can fly in the air like an aircraft, has good maneuverability and a wide field of vision, and can...

Problems solved by technology

[0006] When the existing cross-media unmanned aerial vehicle enters the water, it generally adopts the mode of folding the wings to dive into the water (as shown in the accompanying drawing figure 1 shown in various forms), rely on their own power devices (such as: water pumps, chemical reaction devices) or vehicles (ejection devices, torpedo launchers or small rocket boosters) when they come out of the water, although it is possible to complete this complete cross-medium However, these designs have some common disadvantages: 1) the high-altitude water entry of the folding device is more destructive to the structure; 2) this type of cross-medium aircraft is a single-shot cross-medium aircraft, and it needs to be adjusted again after launching once. Use; 3) When switching to a fixed-wing flight state after exiting the water, the control requirements are relatively high, that is, the control is difficult
