The following is a detailed description of the motion control of the first profile control unit 500 located at the front of the rib:

in the actual movement of the rib structure, as long as the relative position change occurs between the wing leading edge support rod 100 and the wing middle support rod 200, whether swinging in the horizontal plane, swinging in the vertical plane, or combined movement in the horizontal and vertical planes, the first slide rod 25 will have relative movement with respect to the first slide ring 24; further, due to the linkage relationship between the wing profile control structure and the wing rib outer frame, the relative motion between the first slide bar 25 and the first slide bar 24 is transmitted to the first rod 43, the second rod 44, the third rod 47, the fourth rod 48, the fifth rod 51, the sixth rod 52, the seventh rod 55 and the eighth rod 56 by the motion between the first slide bar base hinge support 31, the second slide bar base hinge support 32, the third slide bar base hinge support 33 and the fourth slide bar base hinge support 34 fixed on the first slide bar 24 and the first slide bar base 30, wherein the linkage relationship between the first rod 43 and the second rod 44 is generated by the second hinge support 46, the linkage relationship between the third rod 47 and the fourth rod 48 is generated by the fourth slide bar support 50, the linkage relationship between the sixth rod 54 and the eighth slide bar base hinge support 58 is generated by the fourth slide bar base hinge support 52, the linkage relationship between the third rod 47 and the fourth rod 48 is generated by the sixth slide bar base hinge support 50 and the eighth slide bar base hinge support 34; furthermore, as a result of the transmission of the relative movement of the first slide ring 24 and the first slide rod 25 to the first pivot bearing 45, the third pivot bearing 49, the fifth pivot bearing 53 and the seventh pivot bearing 57, the relative movement of the first slide ring 24 and the first slide rod 25 is transmitted to the first rib edge 2, the second rib edge 4, the seventh rib edge 12 and the eighth rib edge 14 which can be deformed passively, so that the first rib edge 2, the second rib edge 4, the seventh rib edge 12 and the eighth rib edge 14 which can be deformed passively can follow the relative movement of the first slide ring 24 and the first slide rod 25.

Further, with the movement of the first rib edge 2, the second rib edge 4, the seventh rib edge 12 and the eighth rib edge 14, the first sealing flexible connector 301 and the fourth sealing flexible connector 1301, which form flexible connections between adjacent rib edges, will also generate a telescopic movement, wherein one end of the first sliding cover plate 302 is fixedly connected with the first rib edge 2 and the other end is a moving end and slidably connected with the second rib edge 4, and with the relative movement of the first rib edge 2 and the second rib edge 4, the moving end of the first sliding cover plate 302 always tightly fits the second rib edge 4; the fourth sliding cover 1302 has one end fixed to the eighth rib edge 14 and the other end being a moving end and slidably connected to the seventh rib edge 12, and the moving end of the fourth sliding cover 1302 closely contacts the seventh rib edge 12 along with the relative movement of the eighth rib edge 14 and the seventh rib edge 12.

In addition, it should be noted that, as the wing leading edge support rod connector 110, it can rotate around the wing leading edge support rod 100 or be fixed, and in a rib structure requiring active change of the angle of attack, it can be used as an active motor; in the wing rib structure for passively changing the attack angle, the wing rib structure can be used as a passively rotatable shaft sleeve.

Of course, the motion control of the second airfoil control unit 600 refers to the first airfoil control unit 500, and is not described in detail herein.

Through the wing rib structure of this embodiment, based on the adjustment of wing section control unit, for example through the motion of wing link or the change of relative position, can realize the motion of wing rib structure, that is to say can realize multiple airfoil deformation to realize the basic action of plane airfoil transform, wherein, fig. 10 and 11 are wing angle of attack change schematic diagrams, make through the motion of wing structure the wing leading edge bracing piece 100, wing middle part bracing piece 200, wing trailing edge bracing piece 300 is in the cross-section of wing rib structure is in same straight line and is a certain contained angle with the horizontal plane, thereby realizes the action of bowing down that fig. 10 shows and the action of pitching up that fig. 11 shows. Of course, as shown in fig. 12 and 13, the rib structure of the embodiment of the present disclosure can also realize the change of the shape of the rib structure, that is, the wing profile is deformed in a telescopic manner, for example, the two wing profile control units drive the rib structure to shrink, for example, the distance between the wing leading edge support rod 100, the wing middle support rod 200, and the wing trailing edge support rod 300 is shortened, so that the first slip ring link 23 and the first slide rod 25 move relatively to realize the wing profile shrinking action shown in fig. 12, or the distance between the wing leading edge support rod 100, the wing middle support rod 200, and the wing trailing edge support rod 300 is increased, so that the two wing profile control units drive the wing rib structure to enlarge, so as to realize the wing profile enlarging action shown in fig. 13. The disclosed embodiment can also realize the wing profile plane bending action of the wing rib structure, and fig. 14 and 15 are schematic diagrams of the wing profile plane bending action of the wing rib structure, where fig. 14 shows a schematic diagram of the wing rib structure bending upwards, and fig. 15 shows a schematic diagram of the wing rib structure bending downwards.

Of course, the above-mentioned wing profile changing actions can realize the plane wing profile changing complex actions through combination: the transformation adopts the permutation and combination of the basic actions of the plane wing profile, belongs to the combined motion and realizes the complex transformation of the wing profile, and the disclosure is not excessively elaborated. Through the rib structure of this embodiment, based on the adjustment of wing section control unit, can realize multiple wing section deformation.
