A dual-channel unmanned aerial vehicle with dual-motor horizontal cloth cooperative control

Abstract

A double-duct UAV with double-motor horizontal cloth cooperative control, including double-duct, double-motor, and rudder surface components. Propellers on both sides, where the planes of the propeller rotation axes on both sides are parallel to but not coplanar with the plane where the dual motors are located; the rudder surface component is located under the duct, and the rudder surface is pushed and deflected by the rocker rod structure to control the attitude and direction of the drone , through the ESC to control the motor speed, adjust the lift force and roll attitude of the UAV, the ESC and the steering gear act synchronously, increase the power output of the dual motors, unify the speed, and make the dual motors correspond to them during the vertical take-off and landing of the UAV The synchronous belt, synchronous wheel, duct and rudder surface components work together to achieve stable take-off and landing and high-speed level sailing. The invention has a triangular symmetrical layout, good structure rigidity, high space utilization rate, double motors are placed horizontally and centrally, synchronous belts are used to cooperate to transmit power to the propeller, and the dual powers have a unified speed to increase the lift force and ensure the take-off and landing process of the drone. The take-off and landing process is stable. At the same time, there is a set of linkage rudder surfaces under the propeller duct on each side, which cooperate with the ESC to realize the pitch, yaw, and roll motion control of the whole machine.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a double-duct unmanned aerial vehicle controlled by a double-motor horizontal cloth cooperatively. Background technique [0002] A drone is a small, unmanned aircraft that can fly autonomously in the air and perform certain tasks.

[0003] In the application process of drones, because of their unmanned driving, their payloads are larger, and more equipment such as cameras can be installed for aerial photography or loads for material delivery. Therefore, in recent years, it has become more efficient and reliable in completing tasks. etc., but there are not many considerations for its structural space optimization, lift enhancement, flexibility of pose change, and stability in the process of rising, stopping, and falling. In addition, during the maneuvering process, the power transmission coordination ability is poor. After a collision or foreign objects fly in, poor resistance

[0004] It is known that modern UAVs need to have a higher speed to generate sufficient lift when taking off and landing, and in order to reduce the vibration frequency, the design of UAVs is more inclined to reduce the number of power structures, resulting in , insufficient power, therefore, most flight accidents occur during take-off and landing; at the same time, for most existing unmanned aerial vehicles, take-off and landing either need a runway, occupy space, and have strict requirements on the ground environment, or use a direct After the turbofan is raised, other thrust blades are used to perform horizontal flight, which not only increases the power structure, but also requires a larger power supply, increases the self-weight, the structure is not compact, and the energy and space utilization is low.
