Description

Technical Field

[0001] The present invention relates to the technical field of aircraft wing design, and in particular to a trailing edge deformation control mechanism of a variable-camber wing. Background Art

[0002] Variable-camber wing technology aims to dynamically and continuously change the camber of the wing profile (airfoil) during flight to adapt to different flight conditions (such as takeoff, cruise, maneuvering, and landing), thereby significantly improving the aircraft's aerodynamic efficiency, fuel economy, maneuverability, and takeoff and landing performance. As a key component of the variable-camber wing, the smooth, controlled deformation of the trailing edge is central to achieving efficient lift increase, drag reduction, and precise control.

[0003] The existing variable-camber wing trailing edge deformation mechanism uses a traditional hinged structure, which makes it difficult to achieve large-angle, continuous and smooth bending deformation of the airfoil trailing edge; in addition, there are some that adjust the wing curvature by adjusting the flexible trailing edge with a telescopic rod, such as the Chinese patent application number 202010432353.4, named Flexible Trailing Edge Module for Trailing Edge Variable-Curvature Wing.

At the same time, the part of the first movable pin shaft 15 that exceeds the first mounting plate 1 can slide along the arc groove in the arc guide plate 13, and the upper part of the first telescopic rod 7 is located between the two spaced-apart first mounting plates 1.

[0034] A second telescopic rod 8 is also provided between the two spaced-apart first mounting plates 1. The end of the second telescopic rod 8 close to the rotating mounting seat 19 is rotatably set on the first mounting plate 1 through a fixed pin 18.

[0035] In this embodiment, when the first movable pin 15 slides in the arc-shaped slide groove of the arc-shaped guide plate 13, it will drive the first mounting plate 1 to rotate. When the second movable pin 16 is in the arc-shaped slide groove of the first mounting plate 1, it will cause the first connecting frame 2 to rotate based on the first mounting plate 1.

[0036] A third telescopic rod 9 is provided at the lower part of the first connecting frame 2, and two groups of second mounting plates 3 are provided at intervals. The third telescopic rod 9 is rotatably connected to the lower parts of the two groups of second mounting plates 3 through a fixed pin shaft 18, and the upper part of the second mounting plate 3 is connected to the first connecting frame 2 through a fixed pin shaft 18.

[0037] A fourth telescopic rod 10 is provided between the two spaced-apart second mounting plates 3. The end of the fourth telescopic rod 10 close to the first connecting frame 2 is rotatably connected to the second mounting plate 3 via a fixed pin 18.

The side of the bottom of the second connecting frame 4 away from the second mounting plate 3 is rotatably connected to the fifth telescopic rod 11 via a fixed pin 18.

[0038] The structure of the second connecting frame 4 is the same as that of the first connecting frame 2 , and the difference between the two is that the size of the second connecting frame 4 is smaller than that of the first connecting frame 2 .

[0039] The upper part of the second connecting frame 4 is rotatably connected to the upper part of the third connecting frame 5 through a fixed pin 18, and the end of the fifth telescopic rod 11 away from the second connecting frame 4 is rotatably connected to the lower part of the third connecting frame 5 through a fixed pin 18. A flexible rib 6 is provided in the middle part of the right side of the third connecting frame 5, and several rotating connecting rings are provided on the upper and lower sides of the flexible rib 6. A connecting rod can be rotatably connected to the rotating connecting ring, and the other end of the connecting rod is also connected to the wing skin by a rotating connection. Therefore, when the flexible rib 6 begins to bend, the flexible rib 6 will drive the connecting rod rotatably connected to it to displace, thereby causing the wing skin to adaptively bend accordingly.

[0040] See Figure 6 The first mounting plate 1 includes a mounting plate body 101, a first mounting hole 102, a second mounting hole 103, a third mounting hole 104, an arc-shaped slide groove 105, a fourth mounting hole 106 and a first hollow area 107. The upper part of the mounting plate body 101 is provided with a first mounting hole 102, and the lower part of the mounting plate body 101 is provided with a third mounting hole 104 and a fourth mounting hole 106. The third mounting hole 104 is located below the first mounting hole 102, and the second mounting hole 103 is located between the first mounting hole 102 and the third mounting hole 104. The upper part of the mounting plate body 101 is provided with an arc-shaped slide groove 105, and the arc-shaped slide groove 105 is located on the right side of the first mounting hole 102. A first hollow area 107 is provided below the arc-shaped slide groove 105. The first hollow area 107 can reduce the weight of components.

[0041] When in use, the first mounting hole 102 is rotatably connected to the upper part of the first telescopic rod 7 through the fixed pin 18, the lower part of the second telescopic rod 8 is rotatably connected to the second mounting hole 103 through the fixed pin 18, the second movable pin 16 can slide in the arc-shaped slide groove 105, the third mounting hole 104 is rotatably connected to the rotating mounting seat 19 through the fixed pin 18, and the fourth mounting hole 106 is rotatably connected to the first connecting frame 2 through the fixed pin 18.

[0042] See Figure 7The first connecting frame 2 includes a connecting frame body 201, a fifth mounting hole 202, a sixth mounting hole 203, a seventh mounting hole 204, an eighth mounting hole 205, a first open slot 206, a second open slot 207 and a second hollow area 208. The second hollow area 208 is provided in the middle of the connecting frame body 201, and the upper part of the connecting frame body 201 is provided with a fifth mounting hole 202 and a seventh mounting hole 204. The fifth mounting hole 202 is used to connect to the first mounting plate 1, and the seventh mounting hole 204 is used to connect to the second mounting plate 3. The sixth mounting hole 203 is provided just below the fifth mounting hole 202, and the eighth mounting hole 205 is provided on the right side of the sixth mounting hole 203. A second open slot 207 is provided at the fifth mounting hole 202. The setting of the second open slot 207 enables the upper part of the second telescopic rod 8 to be inserted into the second open slot 207, so that the upper part of the second telescopic rod 8 is rotatably connected to the first connecting frame 2 through the fixing pin 18.

[0043] A first opening slot 206 is provided at the eighth mounting hole 205 , and the first opening slot 206 can be used to mount one end of the third telescopic rod 9 .

[0044] The distance between the sixth mounting hole 203 and the seventh mounting hole 204 is smaller than the distance between the fifth mounting hole 202 and the seventh mounting hole 204 .

[0045] See Figure 4-Figure 5 During use, when the trailing edge of the aircraft needs to bend downward, the first telescopic rod 7 begins to extend. The extension of the first telescopic rod 7 drives the first mounting plate 1 to rotate along the rotating mounting seat 19 in the direction away from the wing rear beam 14, and synchronously contracts the third telescopic rod 9 and the fifth telescopic rod 11. When the third telescopic rod 9 contracts, the second mounting plate 3 begins to deflect toward the first connecting frame 2, and the third connecting frame 5 begins to deflect toward the second connecting frame 4. The third connecting frame 5 drives the flexible rib 6 to deflect, thereby completing the downward bending deformation of the trailing edge of the wing. In addition, when the third telescopic rod 9 and the fifth telescopic rod 11 contract, the second telescopic rod 8 and the fourth telescopic rod 10 can also contract slightly.

[0046] When the first telescopic rod 7 begins to retract, it will drive the first mounting plate 1 to rotate along the rotating mounting seat 19 toward the wing rear beam 14, and synchronously, the second telescopic rod 8 and the fourth telescopic rod 10 also begin to retract; when the second telescopic rod 8 retracts, it will drive the first connecting frame 2 to rotate toward the first mounting plate 1, and when the fourth telescopic rod 10 retracts, it will drive the second connecting frame 4 to rotate toward the second mounting plate 3; at this time, the third telescopic rod 9 and the fifth telescopic rod 11 can remain stationary, or when the contraction amount of the second telescopic rod 8 and the fourth telescopic rod 10 is small, the third telescopic rod 9 and the fifth telescopic rod 11 can also be extended synchronously, so that the trailing edge of the wing can achieve an upward bending deformation action.

[0047] See Figure 8 , multiple deformation control mechanisms can be installed side by side to achieve the overall deformation of the wing trailing edge.

[0048] In addition, considering the installation of the wing skin, a rotating connecting ring is provided at the bottom of the second mounting plate 3 or the upper part of the second connecting frame 4 for installing a connecting rod, thereby controlling the deformation of the wing skin.
