[0025] The following embodiments further illustrate the technical solutions of the present application. It is understood that the specific embodiments described herein are merely for the purpose of explaining the present application. It should also be noted that, for ease of description, only portions relevant to the present application are shown in the accompanying drawings, not all of them.

[0026] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application in specific contexts.

[0027] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0028] This application provides a method for quickly adding a canard outer section, comprising:

[0029] S1: Provide a canard outer section 100;

[0030] S2: Provide a drone fuselage, wherein an organic arm 200 is provided on the fixed wing of the drone fuselage;

[0031] S3: Insert the canard outer section 100 into the arm 200. The canard outer section 100 includes a positioning piece 110 and a locking piece 120. After the canard outer section 100 is installed in a fixed position of the arm 200 through the positioning piece 110, the canard outer section 100 and the arm 200 are locked by the locking piece 120.

[0032] By quickly adding canard segments, the lift of the fixed-wing aircraft can be increased by 8%-20% compared to the original lift value of the original aircraft flight platform. The installation of the quickly removable canard segments can overcome the nose-down effect during flight, avoiding undesirable pitching moments that would otherwise affect the UAV's flight efficiency due to the need to compensate for such moments. Furthermore, the combination of the canard segments with the original aircraft flight platform improves the aircraft's static stability margin by approximately 2%, thereby reducing control losses in the flight control system.

[0033] Furthermore, the canard outer section 100 extends from the end away from the fixed wing to the end closer to the fixed wing. Its cross-section along the thickness direction is divided into three regions by a positioning member 110: a first region, a second region, and a third region. The locking member 120 is located in the first region. The locking member 120 extends from the end of the canard outer section 100 away from the fixed wing to one of the upper and lower wing surfaces of the canard outer section 100 away from the fixed wing. The positioning member 110 can quickly position the canard outer section 100 on the aircraft arm.

[0034] Specifically, in the present application, the positioning member 110 includes a first positioning member and a second positioning member. The first positioning member is located at the junction of the first area and the second area, and the second positioning member is located at the junction of the second area and the third area. Preferably, the diameter range of the positioning member 110 is 20mm-40mm.

[0035] In this embodiment, the diameter of the first positioning member is larger than that of the second positioning member to withstand greater stress on the machine arm. The diameter ratio between the first positioning member and the second positioning member is 1.44:1. Of course, in other embodiments, the diameter of the first positioning member may also be equal to the diameter of the second positioning member.

[0036] The present invention uses two sets of positioning parts to nest with each other and cooperate with locking parts to position and fasten the outer section of the canard. The canard can be quickly positioned and fixed to the original aircraft fuselage within 20 minutes to meet the different load requirements of the UAV during cruising.

[0037] Furthermore, the canard outer section 100 includes a fixing seat 130. Before inserting the canard outer section 100 into the aircraft arm 200 in step S3, the step also includes S30: placing the fixing seat 130 in the canard outer section 100. The canard outer section 100 is the area enclosed by the upper and lower wing surfaces of the canard outer section 100 away from the fixed wing and the intersection of the upper and lower wing surfaces of the canard outer section 100 close to the fixed wing.

[0038] For example, a mounting hole is provided on a fixing seat 130 placed in the canard outer section 100. One end of the positioning member 110 is connected to the fixing seat placed in the canard outer section 100 through the mounting hole of the fixing seat 130, and the other end of the positioning member 110 is connected to the aircraft arm 200. Preferably, the positioning member 110 is fixed to the canard outer section 100 by gluing.

[0039] It is worth noting that in the present application, the locking member 120 includes a bolt and a locking member 121, and the locking member 121 has an internal thread that engages with the bolt to limit the displacement of the bolt; locking the canard outer section 100 and the arm 200 by the locking member 120 specifically includes: after installing the bolt in the first area, locking the canard outer section 100 and the arm 200 by the locking member 121.

[0040] Preferably, the length of the longest line connecting the two ends of the outer peripheral surface of the locking member 121 is greater than the length of the longest line connecting the two points on the cross section of the locking member 121 in the thickness direction of the canard outer section in the first area, so that the locking member 121 will not rotate with the bolt, that is, the locking member 121 can play an anti-loosening effect.

[0041] The present application also provides a drone, which includes a canard outer segment 100 locked using the method for quickly adding a canard outer segment described in the above solution.

[0042] The above embodiments are merely illustrative of the principles and effects of this application. Anyone skilled in the art may modify or alter the above embodiments without departing from the objectives of this application. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the objectives disclosed herein are intended to be covered by the claims of this application.
