Air, water and underwater triphibious unmanned aerial vehicle

Abstract

The invention discloses an air, water and underwater triphibious unmanned aerial vehicle. Through a rotatable wing and retractable ducted engines on the two sides of an unmanned aerial vehicle body, thee working modes of air flying mode, a water surface sailing mode and an underwater submerging mode are realized. In the flying mode, the wing is perpendicular to the unmanned aerial vehicle body andis locked, the unmanned aerial vehicle is as same as a three-wing-surface aircraft, a canard and horizontal tail and a control surface thereof provide longitudinal stability and operating moment forthe unmanned aerial vehicle; in the sailing mode, the wing and the unmanned aerial vehicle body are integrated to form a streamline-shaped flat spindle shape, and the canard and the horizontal tail are in contact with a water medium as hydrofoils to generate a hydrodynamic lift so that the sailing performance is improved; and in the submerging mode, the wing and the unmanned aerial vehicle body are integrated to form a streamline-shaped flat spindle shape, the ducted engines on the two sides of the unmanned aerial vehicle body are folded into the unmanned aerial vehicle body, and a tail propeller provides powder so that the unmanned aerial vehicle realizes submerging. By using a tail fin, hydrofoil and water rudder integrated design, the air, water and underwater triphibious unmanned aerial vehicle has the advantages that the structure of the unmanned aerial vehicle is optimized, the integration degree of the system is enhanced, and the structural weight and resistance of the unmannedaerial vehicle are reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an amphibious unmanned aerial vehicle capable of flying in the air, navigating on the water surface and submerging underwater. Background technique [0002] With the development of aviation and marine industry technology, UAVs can realize multiple working modes of air flight, water navigation, land driving and underwater diving. At present, water-air dual-purpose UAVs are mostly designed according to the design concept of seaplanes, which are only developed for air flight and water navigation, and the speed of water navigation is relatively slow; amphibious UAVs are designed for air flight, land exercise and water navigation. Developed and does not have the ability to dive underwater. With the advancement of UAV technology, amphibious UAVs that can simultaneously realize air flight, water navigation and underwater submersion are the future development direction ...

AI Technical Summary

Problems solved by technology

The water-air dual-purpose drone realizes the drone's air flight and water navigation through two sets of independent power devices, but it cannot dive underwater, which limits its application field

[0005] There are some difficulties in the research on multi-habitat search and rescue vehicles at home and abroad. In 2008, the American Advanced Planning and Research Bureau proposed the idea of ​​a hybrid flight platform, which integrates air flight, surface navigation, and underwater diving, but is limited to issues such as layout design and power systems. failed to complete
