Background
The small-sized airplane is limited by the structure size and the manufacturing cost of the airplane body, a mechanical control mode is usually selected for the control surface, and the mechanical control mode is not provided with an automatic control system capable of actively inhibiting the flutter winding, so that the control surface needs to be provided with a balance weight to enable the gravity center of the control surface to be positioned near a rotating shaft so as to avoid the flutter phenomenon. Meanwhile, the rotating shaft of the control surface is generally positioned near a chord plane of the control surface, and the position of the control connecting point rotating around the rotating shaft is selected to meet the requirement on the length of the control force arm so as to improve the control efficiency. However, the height of the wing profile is limited, the control connection point cannot be designed according to the conventional structure, and the control connection point is often arranged outside the wing profile, so that the aerodynamic profile is adversely affected.

In order to solve at least one of the technical problems, the application provides a control surface multifunctional end rib of a small airplane.
The application discloses multi-functional end rib of control surface of small aircraft includes:
the web plate is provided with edge strips extending along the vertical direction at the edges of two sides of the web plate;
the counterweight part is fixedly arranged at one end part of the web plate close to the front edge of the control surface;
and the control connection lug is fixedly arranged on the counterweight part and is used for connecting a control system.
According to at least one embodiment of the application, the end surface of the counterweight part, which faces away from the web, is provided with a curved surface shape matched with the front edge of the control surface.
According to at least one embodiment of the application, a drain hole is formed in one end of the web close to the trailing edge of the control surface.
According to at least one embodiment of the present application, the steering connection tab is of a monaural or binaural configuration.
The application has at least the following beneficial technical effects:
the multifunctional control surface end rib of the small airplane can solve the problem of arrangement of control points of the small airplane, ensures the length of a control force arm and avoids the phenomenon that the aerodynamic efficiency is influenced by the fact that part of the structure protrudes out of the theoretical appearance; and moreover, the number of control surface structural parts and fasteners can be reduced, the manufacturing cost is reduced, the flutter phenomenon of the control surface is avoided, and the potential safety hazard of flight is eliminated.

The multifunctional rudder face end rib of the small airplane of the present application will be described in further detail with reference to fig. 1 to 3.
The application discloses multi-functional end rib of control surface of small aircraft can include, web 2, bead 1, counter weight portion 3 and control connection lug 4.
Specifically, the shape of the web 2 is the same as the cross-sectional shape of the control surface, and the flanges 1 are vertically extended at the edges of two sides (upper and lower sides in fig. 1) of the web 2; wherein, the edge strip 1 is used for connecting the skin with a part of the beam edge strip, and the width of the edge strip 1 can be designed according to the structural margin required by the connecting fastener.
The counterweight part 3 is fixedly arranged at one end part of the web plate 2 close to the front edge of the control surface; the counterweight part 3 can change the shape and the weight to adjust the gravity center of the control surface, and the end surface of one end of the counterweight part 3, which is back to the web plate 2, is set into a curved surface shape matched with the front edge of the control surface.
