Amphibious cross-medium aircraft and cross-medium control method thereof

Abstract

The invention discloses an amphibious cross-medium aircraft and a cross-medium control method thereof. The whole aircraft is of a multi-rotor structure, wherein the number N of rotors is an even number greater than 4; a power system comprises n * N power units, each rotor is provided with n power units, and each power unit comprises a propeller and a motor used for driving the propeller, the total power P of each motor in the power system is not less than three times of hovering power of the whole machine, and the total thrust is not less than 1.5 times of dead weight of the whole machine; the horizontal size t of the cross-medium aircraft is far larger than or far smaller than the wavelength of waves to enter and exit the water area, and the overall density is larger than the density of water to enter the water area. According to the amphibious cross-medium aircraft, a multi-rotor structure is adopted, the compatibility to two working environments is effectively improved, the amphibious cross-medium aircraft can rapidly enter water, the serious influence of water surface fluctuation on stable water outlet is jointly solved through size design and power design of a power system, the water outlet speed can be shortened to be within 1 s, and the water outlet reliability can reach 99.8% or above.

Description

technical field [0001] The application belongs to the technical field of unmanned aerial vehicles, and in particular relates to an amphibious cross-medium aircraft and a cross-medium control method thereof. Background technique [0002] The amphibious trans-medium aircraft integrates three unmanned working systems of air vehicle, surface vehicle and underwater vehicle, and can simultaneously have three functions of air flight, surface navigation and underwater diving on a single platform. The platform is not only maneuverable and flexible, but also better able to adapt to various environmental conditions, and has certain versatility and concealment. [0003] The amphibious cross-medium vehicle breaks through the limitations of the traditional single-medium unmanned system platform. It has both the flight characteristics of a surface vehicle and the stealth characteristics of an underwater vehicle, so it has excellent environmental adaptability. At the same time, it can effe...

AI Technical Summary

Problems solved by technology

[0006] To sum up the above, in various scientific research institutions at home and abroad, the existing achievements are not mature and reliable to achieve cross-medium flight

Some cannot achieve autonomous cross-medium, and can only navigate in a single-medium environment; some use variant structures to achieve cross-medium flight, which increases the complexity

Therefore, none of the current research results can be mass-produced and put into operation in a short period of time.

With the continuous development of information, the task requirements of target users become more and more complex, and the tasks undertaken by the unmanned aerial vehicle platform become more and more difficult.
