Embodiment 1
[0029] Such as 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 conn...

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. In the present invention, the rotation of the steering gear drives the steering gear disc and the steering gear connecting rod to rotate, thereby changing the inclination direction of the swash plate device. The swash plate device can be tilted around the central spherical hinge to generate an inclination angle, thereby realizing free control of the plane of the swash plate device. The change of the plane of the swash plate device brings about the change of the plane inclination of the upper rotor, which makes the direction of the lift surface of the upper rotor change, so that the aircraft can fly in all directions. This set of control mechanism is not complicated, but also realizes the control of the coaxial anti-propeller three-bladed rotor structure. Since the steering gear controls the plane inclination angle of the swash plate device, it is also more efficient than other similar aircraft in the design of its control system. easy. On the premise of realizing the function of the coaxial anti-propeller UAV and giving full play to its advantages, the present invention can overcome the complicated structure of the conventional coaxial anti-propeller UAV and reduce the design difficulty of its control system.
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...
