Description

Technical Field

[0001] The present application relates to the field of aviation equipment, and in particular to a lift-increasing wing. Background Art

[0002] The wing is an important part of an aircraft. Its main function is to provide lift, and together with the tail, it ensures that the aircraft has good stability. The principle of wing lift is that after the air flows over the leading edge of the wing, the airflow flowing over the upper surface of the wing has a high velocity and low air pressure, while the airflow flowing over the lower surface of the wing has a low velocity and high air pressure. The pressure difference between the upper and lower surfaces of the wing forms the lift of the wing.

[0003] The air in front of the wing and within the thickness of the wing will be divided into two parts by the forward-moving leading edge of the wing and form pressure on the upper and lower surfaces of the wing. These airflows will generate upward and downward reaction forces, i.e. pressure, on the wing while moving backward and upward and backward and downward. The difference between these two pressures actually forms the lift of the wing.

[0004] From this we can see that the wingspan of the wing plays an important role in the size of the lift. When a larger lift is required, a larger wing span is needed, but a wingspan that is too large will cause the aircraft to occupy more space and make the aircraft heavier, which will result in more lift being required, resulting in insufficient utilization of aerokinetic energy. Summary of the invention

[0005] The purpose of the present application is to provide a lift-increasing wing for improving the structure of the wing, increasing the lift of the wing, thereby shortening the wing length and improving the wing efficiency.

[0006] The lift-increasing wing provided in this application adopts the following technical solution:

[0007] A lift-increasing wing comprises a plurality of single wings arranged side by side, wherein a plurality of through holes are opened on the single wings, the through holes on all the single wings are arranged correspondingly, and connecting rods are further arranged in the through holes of the single wings, wherein the connecting rods pass through all the single wings along the through holes, and a lift-increasing structure is arranged inside the single wings.

[0008] By adopting the above technical solution, all the single wings can be connected in series through connecting rods to form a wing, wherein the lift increasing structure in the single wing can provide lift for the single wing, so that the entire wing can obtain more lift, thereby shortening the wing length and reducing the wing weight while meeting the lift requirement, thereby reducing space occupancy. The wing is composed of multiple single wings, and the wing length can be quickly adjusted by disassembling the single wing, which can better utilize air kinetic energy.

[0009] Optionally, the upper side surface of the single wing is set to be a curved surface, and the lift increasing structure includes a guide channel opened inside the single wing, the guide channel includes an air inlet and an air outlet, the direction of the air outlet is consistent with the curvature direction of the upper side surface of the single wing, lift pieces are provided on both sides of the air inlet, and the number of lift pieces on the side of the air inlet close to the upper side surface of the single wing is less than the number of lift pieces on the other side.

[0010] By adopting the above technical solution, the difference in the number of lift members on both sides of the air inlet makes the airflow velocity on one side of the air inlet close to the upper side of the single wing smaller than the airflow velocity on the other side, thereby reducing the possibility of single wing vibration caused by airflow turbulence inside the air inlet. At the same time, the arc surface of the upper side of the single wing makes the airflow velocity large and the pressure low, while the airflow velocity on the lower side of the single wing is slow and the pressure is large. The pressure inside the single wing is greater than that on the upper side of the single wing, but lower than that on the lower side of the single wing. Therefore, the pressure on the lower side of the single wing is greater than that on the air inlet close to the lower side of the single wing. The pressure is increased, thereby increasing the lift of the single wing. At the same time, the pressure on the side of the air inlet close to the upper side of the single wing is greater than the pressure on the upper side of the single wing, thereby further increasing the lift of the single wing. In addition, when the airflow from the air inlet reaches the air outlet, a thrust is applied to the side of the air outlet close to the upper side of the single wing, so that the air outlet obtains an upward thrust, further enhancing the lift of the single wing. Finally, at the outlet of the air outlet, the two airflows converge to form a vortex, which then lifts the single wing again. Therefore, with the addition of multiple lifts, the lift of the single wing is greatly enhanced.

[0011] Optionally, the lift member includes a partition plate, and a lift groove corresponding to the partition plate is opened on the inner wall of the air inlet portion. A slope protruding toward the center line of the air inlet portion is provided on the side of the lift groove opening away from the air outlet portion, and a speed increasing channel is formed between the partition plate and the lift groove.

[0012] By adopting the above technical solution, when the airflow flows to the slope, a negative pressure area is formed between the partition plate and the slope, so that the speed increase channel between the partition plate and the lift groove forms a near vacuum, thereby applying a forward-flowing suction and pulling force to the airflow in the channel on the side of the partition plate away from the slope, so that the airflow in the air inlet can flow quickly, and the number of lift members on both sides of the air inlet is different, resulting in different airflow velocities on both sides, and the pressure on the lower side of the single wing is greater than the pressure on the side of the air inlet close to the lower side of the single wing, and the pressure on the side of the air inlet close to the upper side of the single wing is greater than the pressure on the side close to the lower side of the single wing, forming a pressure difference in the air inlet drainage channel, generating an upward lift.

[0013] Optionally, a diverter plate is provided at a middle position of the air outlet portion, the length of the diverter plate is smaller than the air outlet portion, and the diverter plate is in the same direction as the air outlet portion.

[0014] By adopting the above technical solution, the splitter plate separates the airflows on both sides of the air inlet at the air outlet, thereby reducing the possibility of single-wing vibration caused by airflow collision.

[0015] Optionally, the diverter plate gradually becomes thicker from both ends to the middle, and arc-shaped protrusions are provided on both side walls of the air outlet portion. The protrusions are arranged corresponding to the middle part of the diverter plate and form a stamping channel.

[0016] By adopting the above technical solution, when the airflow inside the air outlet reaches a certain speed, air flow compression air is gradually formed in the middle position of the diverter plate, and at the same time, fuel is injected into the high-pressure air flow position and ignited, thereby forming a high-pressure combustion jet, and ejected out at the outlet of the air outlet, thereby increasing the power of the single wing, thereby increasing the power and endurance of the single wing.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. The lift-increasing structure in the single wing can provide lift for the single wing, so that the entire wing can obtain more lift. Therefore, when the lift requirement is met, the wing length can be shortened, the wing weight can be reduced, and the space occupation can be reduced. The wing is composed of multiple single wings, and the wing length can be quickly adjusted by disassembling the single wing;

[0019] 2. When the airflow inside the air outlet reaches a certain speed, compressed air is formed in the middle position of the splitter plate, and fuel is injected into this position and ignited, thereby forming a high-pressure combustion jet, which is ejected from the outlet of the air outlet, thereby increasing the power of the single wing, thereby increasing the power and endurance of the single wing.

[0024] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0025] Embodiment 1: A lift-increasing wing, referring to Figure 1 and Figure 2, including a plurality of single wings 1, the upper side of the single wing 1 is arranged in an arc shape, three through holes 11 are opened on the single wing 1, and the plurality of single wings 1 are arranged side by side, and the through holes 11 correspond to each other. A connecting rod 12 penetrating all the single wings 1 is arranged in the through hole 11, so that all the single wings 1 are arranged stably. The upper side of the single wing 1 is arranged in an arc shape, so that during the movement of the single wing 1, the airflow speed on the upper side of the single wing 1 is large, the pressure on the upper side of the single wing 1 is small, and the pressure on the lower side of the single wing 1 is greater than the pressure on the upper side of the single wing 1, so there is lift. In addition, a lift-increasing structure is added inside the single wing 1.

[0026] All the single wings 1 are connected in series through the connecting rod 12 to form a wing. The wing is composed of multiple single wings 1. The wing length can be quickly adjusted by disassembling the single wings 1. Among them, the lift-increasing structure in the single wing 1 can provide lift for the single wing 1, so that the entire wing can obtain more lift, thereby shortening the wing length and reducing the wing weight when the lift requirement is met, thereby reducing the space occupation.

[0027] The lift increasing structure includes a guide channel 2 opened inside the single wing 1, the guide channel 2 includes an air inlet 21 and an air outlet 22, the direction of the air outlet 22 is consistent with the curvature direction of the upper side of the single wing 1, and lift pieces are provided on the upper and lower sides of the air inlet 21, one lift piece is provided on the upper side of the air inlet 21, and two lift pieces are provided on the lower side of the air inlet 21.

[0028] The lift member includes a partition plate 3, and a lift groove 211 corresponding to the partition plate 3 is opened on the inner wall of the air inlet portion 21. The partition plate 3 is located at the notch of the lift groove 211. The side of the notch of the lift groove 211 away from the air outlet portion 22 is provided with a slope protruding toward the center line of the air inlet portion 21. A speed-increasing channel is formed between the partition plate 3 and the lift groove 211, and the distance between the top of the slope and the center line of the air inlet portion 21 is smaller than the distance between the partition plate 3 and the center line of the air inlet portion 21.

[0029] When the airflow flows to the slope, a negative pressure area is formed between the partition plate 3 and the slope, so that the speed increase channel between the partition plate 3 and the lift groove 211 forms a near vacuum, thereby applying a forward-flowing suction and pulling force to the airflow in the channel on the side of the partition plate 3 away from the slope, so that the airflow in the air inlet 21 can flow quickly. The different numbers of lift members on both sides of the air inlet 21 result in different air flow velocities on both sides, thereby reducing the possibility of air flow turbulence inside the air inlet 21 causing vibration of the single wing 1, and forming a pressure on the lower side of the single wing 1 that is greater than the pressure on the side of the air inlet 21 close to the lower side of the single wing 1, and a pressure on the side of the air inlet 21 close to the upper side of the single wing 1 is greater than the pressure close to the lower side of the single wing 1.

[0030] The pressure on the lower side of the single wing 1 is greater than the pressure on the side of the air inlet 21 close to the lower side of the single wing 1, thereby increasing the lift of the single wing 1. At the same time, the pressure on the side of the air inlet 21 close to the upper side of the single wing 1 is greater than the pressure on the upper side of the single wing 1, thereby further increasing the lift of the single wing 1. In addition, when the airflow of the air inlet 21 reaches the air outlet 22, a thrust is applied to the side of the air outlet 22 close to the upper side of the single wing 1, so that the air outlet 22 obtains an upward thrust, further improving the lift of the single wing 1. Finally, at the outlet of the air outlet 22, the two airflows converge to form a vortex, and then lift the single wing 1 again. Therefore, with the addition of multiple lifts, the lift of the single wing 1 is greatly improved.

[0031] A splitter plate 4 is installed in the middle of the air outlet 22. The splitter plate 4 is shorter than the air outlet 22 and has the same direction as the air outlet 22. The splitter plate 4 separates the airflows on both sides of the air inlet 21 at the air outlet 22, reducing the possibility of vibration of the single wing 1 caused by airflow collision.

[0032] The implementation principle of Example 1 of the present application is as follows: after the airflow enters the guide channel 2, it is accelerated by the lift member, thereby increasing the lift of the single wing 1. At the same time, the lift member and the splitter plate 4 stabilize the airflow, reduce the possibility of airflow collision, and thus stabilize the wing.

[0033] Embodiment 2: A lift-increasing wing, referring to Figure 3 , which is different from Example 1 in that the splitter plate 4 gradually becomes thicker from both ends to the middle, and arc-shaped protrusions 5 are fixed on both side walls of the air outlet, and the protrusions 5 and the splitter plate 4 are close to each other and the protruding position forms a ramming channel. When the airflow inside the air outlet 22 reaches a certain speed, the ramming channel at the middle position of the splitter plate 4 forms an airflow ramming air, and at the same time, fuel is injected into the high-pressure airflow position and ignited, thereby forming a high-pressure combustion jet, and ejected at the outlet of the air outlet 22, thereby increasing the power of the single wing 1, thereby increasing the power and endurance of the single wing 1.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
