The invention discloses a method for shielding a gap of an unmanned aerial vehicle motion structure, and relates to the technical field of unmanned aerial vehicle. The method for shielding the gap of the unmanned aerial vehicle motion structure comprises the following steps: S1, initially determining the outline dimension of a shielding plate according to the size of the gap and a deflection condition of a rudder surface; S2, determining a connection mode of the shielding plate in the S1 and a machine body according to a structure form of the rudder surface and the machine body; S3, determining an initial pressing force of the shielding plate according to an aerodynamic load, then combining with the interface dimension of the shielding plate, and determining the elastic modulus required by the plate; S4, determining a material composite layering way and a shielding plate connection mode, and manufacturing the shielding plate; S5, determining a pre-deformation angle of the shielding plate; S6, determining an outline structure of the final shielding plate; and S7, spraying a conductive coating and a camouflage coating on the outer surface of the molded shielding plate. The method has the beneficial effects that the shielding plate in the method can satisfy the requirement of the camouflage performance under a condition without affecting the normal deflection of the rudder surface.
Description
technical field [0001] The invention relates to the technical field of drones, in particular to a method for blocking gaps in the motion structure of drones. Background technique [0002] Stealth is one of the main design features of a UAV. When the rudder surface and other moving parts are deflected, the rudder surface forms a gap with the fixed parts such as the wing surface or the fuselage, which blocks the overall electrical continuity of the fuselage and cannot achieve Stealth required. Therefore, it is necessary to install a plate to cover the gap and ensure electrical continuity to meet the requirements of the stealth function. [0003] In order to achieve the effect that the gaps are completely covered, when the rudder surface is in various deflection states, this kind of plate should be closely attached to the surface of the movable part, that is, it has follow-up performance, and at the same time it does not affect the normal deflection of the rudder surface.
