Description

TECHNICAL FIELD

[0001] The utility model relates to unmanned plane field especially single power multidirectional linkage coaxial unmanned plane. BACKGROUND

[0002] In the world of model aircraft, remote control helicopter models are a type of product that is deeply favored by enthusiasts. It is mainly divided into two categories: electric and oil-powered. These two types of models, based on different power sources, have their own unique performance and characteristics.

[0003] Electric helicopter models, whose power core is brushless motor. Brushless motor, with its high efficiency and stability, drives the rotor to rotate quickly, thereby generating the power needed for flight. This model structure is relatively simple, easy to operate, and very convenient to start and stop. Moreover, it has relatively low noise during operation, making it very suitable for use in densely populated places such as urban communities and parks. However, its endurance is limited by battery capacity, and the flight time is relatively short.

[0004] Oil-powered helicopter models use fuel engines as a power source. Fuel engines have powerful power output, providing sustained and powerful power to the model, greatly extending the model's endurance time. It can perform long-time flight performances or long-distance flight explorations, and is suitable for open field sites or professional model aircraft flying sites. However, the structure of oil-powered models is more complex, and the operation is more difficult. Starting and maintaining it requires certain professional knowledge and skills, and it also produces more noise when running.

[0005] Remote control helicopter models can fly freely in the air, and the principle behind it is the result of multiple coordinated actions. When the main rotor rotates, it produces relative motion with the air, and according to Bernoulli's principle, the air produces a pressure difference on the upper and lower surfaces of the main rotor, thereby generating upward lift, which is the key to the helicopter's ability to take off. However, the main rotor will produce a counter-torque when it rotates, and if it is not counteracted, the helicopter will spin in place. The tail rotor serves this purpose, as it generates a lateral force to balance the counter-torque produced by the main rotor, ensuring stable flight of the helicopter.

[0006] In addition to counteracting the counter-torque, the tail rotor also has other important functions. It can balance the center of gravity of the aircraft, keeping the helicopter balanced during flight. At the same time, the tail rotor can also increase the speed of the aircraft when flying forward, allowing the helicopter to maintain a small attitude change when flying at high speed, ensuring the stability of the flight.

[0007] Through a series of operations, the helicopter can realize hovering, turning, lifting and other basic actions. For example, by adjusting the angle of the rotor blades, that is, by changing the pitch, the helicopter can realize forward and backward flight and left and right flight. When changing the angle of the blades, the direction and size of the lift generated by the main rotor will also change, so that the helicopter moves in different directions. The up and down movement of the heading lever can change the speed of the tail rotor, realize differential speed, and thus change the heading of the helicopter.

[0008] The simplified structure model is designed to more intuitively demonstrate the flight principle of the helicopter. It mainly includes the main rotor, tail rotor and transmission system and other core components. These components simulate the flap hinge, flapping hinge and pitch hinge structure of the real helicopter. Through the demonstration of these structures, people can better understand the dynamic balance principle of the rotor.

[0009] The tilt disc (cross disc) linkage device is an important part of the simplified structure model. It can demonstrate the periodic pitch change process of the rotor blades. When the tilt disc tilts, it will cause the angle of the rotor blades to change periodically, thereby changing the direction and size of the lift. In this way, the relationship between lift tilt and flight direction control can be explained. This model is like a vivid teaching tool that can help students better understand the complex flight principle of the helicopter.

[0010] However, in actual application, the remote control helicopter model has certain limitations in principle demonstration. In project demonstration, customer communication and other scenarios, due to the complex aerodynamics and mechanical structure knowledge involved in the principle of unmanned aerial vehicle, it is difficult to clearly and intuitively demonstrate through existing means. The existing models and demonstration means can only demonstrate some superficial phenomena and cannot deeply explain the principle.

[0011] Moreover, most of the devices currently used for principle demonstration are single-function, and have no other purposes besides demonstrating the principle. This not only causes waste of resources, but also limits its application in more fields. Therefore, developing a device that can clearly demonstrate the principle of unmanned aerial vehicle and has multiple purposes has important practical significance.

[0012] And because of the volume limitation, the number of parts can be reduced, which can save costs;

[0013] Therefore, the linkage relationship must be simple and clear enough.

[0014] In summary, the defects of the prior art are:

[0015] The volume is too large and the number of parts is too many;

[0016] The transmission relationship is not simple enough;

[0017] The cost is too high;

[0018] Too single.
