Air-launched unmanned aerial vehicle

Abstract

The invention discloses an air-launched unmanned aerial vehicle. The unmanned aerial vehicle comprises a fuselage, a main wing assembly and a main wing folding structure, the main wing folding structure comprises a main wing platform, a main wing driving assembly and a main wing limiting assembly, and the main wing assembly comprises a left main wing and a right main wing; when the main wing assembly is folded, the left main wing and the right main wing are stacked in the length direction of the fuselage; when the main wing assembly is unfolded, the left main wing and the right main wing are flush in height and extend towards the two sides of the fuselage respectively; the main wing limiting assembly is movably connected with the main wing rotating assembly so as to limit the main wing assembly to be in a folded state when the main wing limiting assembly is effective; and the main wing driving assembly is in transmission connection with the main wing rotating assembly so as to drive the main wing rotating assembly to rotate and be converted into the unfolding state when the main wing limiting assembly loses efficacy. On the premise that the folding size is small, the functions of eliminating the height difference after the main wing is unfolded and having the dihedral angle are achieved at the same time, and the unmanned aerial vehicle has better aerodynamic performance while being convenient to store and transport.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an air-launched unmanned aerial vehicle. Background technique [0002] UAV has developed into an irreplaceable equipment, performing tasks such as long-endurance reconnaissance, area surveillance, search and positioning, and fire guidance. Air-launched UAVs are a type of UAVs that are launched from air platforms such as fixed-wing aircraft, helicopters, or UAVs, and perform tasks such as air surveillance range expansion, decoy defense, electronic countermeasures, and cluster attacks. Air-launched UAVs usually require a long battery life, requiring UAVs to have a high lift-to-drag ratio. At the same time, in order to meet the requirements of portable transportation, UAVs are required to occupy less space during the storage, transportation and use stages of UAVs. small. [0003] Among the currently public UAVs, the disassembled ones account for the vast majority....

AI Technical Summary

Problems solved by technology

However, the size of the disassembled packing box is still large, and the disassembly and assembly process is time-consuming and laborious

There are very few foldable UAV solutions. These solutions have complex structures, low reliability, cannot avoid the height difference between the wings of the UAV, and cannot take into account the aerodynamic layout of high lift-to-drag ratio and compact storage.
