Abstract

The invention relates to an aircraft and provides an unmanned aerial vehicle based on coaxial multi-rotor-wing posture adjustment so as to solve the problems that an existing single-propeller aircraft is poor in reliability and large in power loss, a multi-axis aircraft is large in weight and poor in carrying capacity, and a coaxial double-rotor-wing aircraft is large in weight and poor in maneuvering performance. The unmanned aerial vehicle based on coaxial multi-rotor-wing posture adjustment comprises a vehicle core, an aircraft frame and a deflection adjusting mechanism; the vehicle core comprises a double-output driving mechanism, a frame and a coaxial multi-rotor-wing mechanism; and the double-output driving mechanism is mounted on the frame, the coaxial multi-rotor-wing mechanism is connected to the two output ends of the double-output driving mechanism, counter rotating propellers are arranged on the coaxial multi-rotor-wing mechanism, a deflection manipulating rod is connected to the bottom of the frame, and the deflection adjusting mechanism is mounted on the aircraft frame and can control the deflection manipulating rod to swing. The unmanned aerial vehicle based on coaxial multi-rotor-wing posture adjustment can be used for aerial photography, agricultural spraying and unmanned probe.

Description

technical field [0001] The invention relates to an aircraft. Specifically, it relates to an unmanned aerial vehicle based on coaxial multi-rotor attitude adjustment. Background technique [0002] Aircraft plays an important role in the aerospace field. Due to its own characteristics, unmanned aerial vehicles are used in many fields such as detection, investigation, and aerial photography. The Austrian Siebel company successfully developed the S-100 unmanned helicopter in 2003. The maximum take-off weight is 200kg, task load 50kg, battery life 4h, can be used for 24-hour all-weather monitoring, area and activity security, border patrol, maritime security and precise measurement and mapping; In July 2011, the U8 unmanned helicopter independently developed by AVIC Helicopter was successfully completed. Completed the first plateau test flight test In July 2011, the U8 unmanned helicopter independently developed by AVIC Helicopter Institute successfully completed the first plate...
