Wing rib-free rapid water injection and drainage wing suitable for sea and air across amphibious unmanned aerial vehicle

Abstract

The invention discloses a wing rib-free rapid water injection and drainage wing suitable for a sea and air across amphibious unmanned aerial vehicle. The wing comprises a left wing component and a right wing component, wherein the left wing component and the right wing component have the identical structure and are symmetrically arranged around the central axis of the body; the wing component comprises a primary wing, a secondary wing, a wing steering engine, a wing rudder, a wing connecting shaft, a carbon fiber rod and a wing longitudinal rib fixing rod; the secondary wing is arranged on the rear edge concave part of the primary wing through the wing connecting shaft; the wing rudder is arranged on the secondary wing; the wing steering engine is arranged on the primary wing; and the carbon fiber rod and the wing longitudinal rib fixing rod are arranged in a wing cavity of the primary wing. A cavity wing rib-free structure is formed in the main wing, so that when the unmanned aerial vehicle enters water, the inner wing cavity can be rapidly filled with water, the average density of the whole body is rapidly increased due to the water injected into the wing part, and underwater navigation is promoted; and meanwhile, when the unmanned aerial vehicle vertically takes off from the water surface, water in the wing cavity can be rapidly discharged, so that the density of the whole body is rapidly reduced, and air flight is promoted.

Description

technical field [0001] The invention relates to a wing for an unmanned aerial vehicle, more particularly, to a ribless rapid water injection and drainage wing suitable for amphibious unmanned aerial vehicles across the sea and air. Background technique [0002] UAV is the abbreviation of unmanned aerial vehicle, and the English abbreviation is UAV (Unmanned Aerial Vehicle). [0003] The most important requirement for the design of the UAV is to be as light as possible while the fuselage system is strong enough. However, UAVs under various mission load requirements leave very limited space and quality quotas for motion transmission mechanisms. It is necessary to flexibly and efficiently convert basic engineering driving motions, such as high-speed rotation, into favorable controlled motions. The basic aviation transmission methods include direct drive, proportional amplification drive, electric servo drive and hydraulic servo drive. [0004] UAV is an unmanned aircraft oper...

AI Technical Summary

Problems solved by technology

[0006] At present, the inner skeleton of the wing of the UAV generally includes a longitudinal skeleton (spar, longitudinal wall, and stringer) and a transverse skeleton (wing ribs). The transverse skeleton ribs have the same shape as the wing section and are distributed along the wing span There are several ribs. Due to the existence of the rib structure, the space inside the wing along the span direction is blocked by the ribs. The wing with this structure is not conducive to the flow of water inside the wing (water injection and drainage), and it is not easy to By changing the overall density of the wing to adjust the average density of the UAV itself, it limits the operation of the UAV in the water environment
