Medium-sized tilt rotor unmanned aerial vehicle

Abstract

The invention belongs to the technical field of unmanned flight and particularly relates to a medium-sized tilt rotor unmanned aerial vehicle. The unmanned aerial vehicle comprises a fuselage, an empennage and two wings, wherein the empennage and the two wings are arranged on the fuselage, each wing comprises a tilting outer wing section and an inner wing section, one end of each inner wing section is fixedly connected with the fuselage, and the other end of each inner wing section is rotatably connected with the corresponding tilting outer wing section; the tilting outer wing section comprises a variable-pitch rotor wing, an outer wing section, a nacelle and an expansion wing, one end of the outer wing section is rotationally connected with the inner wing section through a rotating shaft, and the other end of the outer wing section is slidably connected with the expansion wing; the nacelle is arranged on the outer wing section, a variable-pitch rotor wing is arranged at the top of the nacelle, and a rotor wing rotation driving system used for driving the variable-pitch rotor wing to rotate is arranged in the nacelle. According to the aircraft, the extension length and angles of the rotors relative to the aircraft body can be adjusted so as to adapt to different flight mission requirements, and flight efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a medium-sized tilt-rotor unmanned aerial vehicle. Background technique [0002] With the increasing complexity of missions and the diversity of demand forms, more and more flight missions require the advantages of both traditional fixed-wing aircraft and rotary-wing aircraft. Traditional fixed-wing aircraft have the characteristics of fast flight speed, large task load, and wide adaptability. However, it has high requirements on the site and needs to build a good runway, so it is not suitable for task deployment in a relatively complex environment. The rotorcraft (helicopter, multi-rotor aircraft) is more suitable for the use requirements of small range and high maneuverability. [0003] In order to meet the requirements of large load, long endurance, and high tilt reliability, it is necessary to develop large and medium-sized tilt-rotor UAVs to meet the actua...
