Embodiment 1

[0029] like figure 1 The structure of the present invention shown is a portable small-sized barrel-type coaxial anti-propeller three-blade rotor type drone. It includes a central shaft 1, a rotor device 2, a load cylinder 3, a driving motor 4, a transmission device 5, and the like. The rotor device 2 includes an upper rotor device and a lower rotor device, the blade is connected with the outer rotor of the motor through a swing hinge 22, a swing hinge 23 and a boss 21, and the folding of the blade can be realized through the connection at the swing hinge 23, Easy to store and carry. The upper and lower rotor devices are mirror images of each other, upside down. The rotor device 2 is connected with the motor rotor through the boss 21 on the outer rotor of the motor. The load tube 3 is equipped with batteries, flight control circuit boards, wires and load modules, etc., and is responsible for the energy supply and flight control of the aircraft. , The drive motor 4 is connect...

Abstract

The invention relates to a portable small cylinder type coaxial reverse propeller three-blade rotor wing type unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles. The steering engine rotates to drive the steering engine disc and the steering engine connecting rod to rotate; the tilting direction of the tilting tray device is changed, the tilting tray device can tilt around the central spherical hinge to generate a tilt angle, so that free control over the plane of the tilting tray device is achieved, the change of the plane of the tilting tray device brings the changeof the plane tendency of the upper rotor wing, the direction of the lift surface of the upper rotor wing is changed, and the aircraft flies in all directions. The control mechanism is not complex, control over the coaxial reverse-propeller three-blade rotor wing structure is achieved, and due to the fact that the steering engine controls the plane inclination angle of the swash plate device, thecontrol system of the coaxial reverse-propeller three-blade rotor wing structure is easier than other similar aircrafts when being designed. On the premise that the functions of the coaxial propellerreversing unmanned aerial vehicle are achieved and the advantages of the coaxial propeller reversing unmanned aerial vehicle are brought into play, the complex structure of an existing coaxial propeller reversing unmanned aerial vehicle can be overcome, and the design difficulty of a control system is lowered.

Description

technical field [0001] The invention relates to a portable small-sized barrel-type coaxial anti-propeller three-blade rotor type unmanned aerial vehicle, which belongs to the field of unmanned aerial vehicles. Background technique [0002] Portable small barrel-type coaxial anti-propeller three-bladed rotor UAV is a small, highly maneuverable, vertical take-off and landing, fixed-point hovering unmanned aerial vehicle. This type of aircraft itself is compact and stable. High stability, high maneuvering and hovering efficiency, its blades can be folded close to the outer wall of the aircraft, forming a cylindrical shape structure, easy to carry and launch, and has good general versatility in both military and civilian aspects. [0003] At present, there are also small coaxial anti-propeller UAVs under research. For example, the coaxial rotor helicopter developed by the research team of Beihang University is based on the motion characteristics of seagulls. Its control mechani...
