[0002] Electric vertical take-off and landing aircraft generally have three mainstream layouts:

[0003] Multi-rotor: 4-8 groups of propellers are evenly arranged on the periphery of the aircraft body, and the lift and control force are provided by controlling the rotation speed of each propeller;

[0004] Tilt-rotor: the fuselage, wings and tail of the conventional aircraft are provided, but the propeller capable of vertical take-off is increased, the propeller thrust axis can be rotated to change the direction of the thrust, and vertical take-off and horizontal flight are realized;

[0005] Compound wing: the fuselage, wings and tail of the conventional aircraft are provided, but the propeller capable of vertical take-off is increased, the propeller works when vertical take-off, stops when horizontal flight, and the special horizontal propeller provides thrust to realize vertical take-off and horizontal flight.

[0006] Among them, the multi-rotor aircraft has the smallest size, the highest hovering control precision and the strongest wind resistance under the same take-off weight because it has no wings, and is suitable for city internal street patrol, aerial photography and other work; but at the same time, the flight time of the multi-rotor aircraft is the shortest because there is no wing to generate additional lift.

[0007] In the current city patrol, road condition monitoring, forest fire prevention, power line patrol and other use scenarios, various aircraft with different characteristics are often required to perform different tasks, so at least two aircrafts need to be carried each time, and are replaced in different working conditions, which also means that in addition to the aircraft body, different ground equipment, different batteries and maintenance equipment need to be carried, causing too many repetitive equipment to be carried each time to perform tasks, which has a serious impact on work efficiency and utilization rate. UTILITY MODEL CONTENT

[0008] The utility model aims to design an aircraft which can realize the switching of two or more flight layouts by replacing different modules, so as to greatly improve the utilization rate of the aircraft in different environments, expand the use range and save costs.

[0013] When the compound wing configuration assembly is installed on the basic structure, the compound wing configuration is formed.

[0014] Further, the compound wing configuration assembly comprises a propulsion motor cabin, a main wing, a tail beam, and a V-shaped tail wing.

[0015] The propulsion motor cabin is installed on the head of the core cabin; the main wing is installed on the lift motor support; and the tail beam and the V-shaped tail wing are installed on the tail of the core cabin.

[0019] Further, when the multi-rotor configuration unmanned aerial vehicle and the compound wing configuration unmanned aerial vehicle are switched, the center of gravity of the unmanned aerial vehicle remains unchanged.

[0020] Advantages:

[0021] The application provides a kind of aircraft for realizing quick switching between multi-rotor configuration and compound wing configuration by quick-release mechanism, which can be used for city point suspension or short distance flight in multi-rotor mode, and can be used for long distance flight in compound wing mode. The two configurations are switched quickly, and can be quickly switched and deployed according to actual needs.

[0022] The application uses modularization to change the configuration of the aircraft for the first time on the unmanned vertical take-off and landing aircraft; the weight and gravity distribution of the modules before and after the change remains unchanged, avoiding additional weight of the aircraft; the key components of the two different configurations of the aircraft are shared, reducing the input cost and increasing the efficiency of the aircraft.
