[0002] Air blowing flow control technology is one of the effective means to improve the short take-off and landing capability of aircraft and enhance the control ability of rudder surface. According to the different deflection angles of the aircraft rudder, the air blowing controllers on both sides of the rudder have different gas supply requirements.

[0003] In the related art, the air supply of the air blowing controller on both sides of the rudder is often adjusted by a traditional electric control valve. However, the electric control valve needs to be composed of multiple components such as a drive motor and a control circuit, and its weight is large, which will bring a significant load to the aircraft. In addition, the electric control valve is expensive to manufacture, and the production and use costs are high. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0022] In order to facilitate understanding of the embodiments of the present application, the relevant technologies are first introduced in conjunction with application scenarios.

[0023] When the aircraft turns by deflecting the rudder, it is necessary to blow air into the air blow controllers on both sides of the rudder. Due to the different rudder deflection angles, the amount of gas required by the air blow controller is also different. In the related art, the amount of gas required to be supplied to the air blow controller at different rudder deflection angles is often adjusted by devices such as electric control valves, but there are problems such as the electric control valves being too heavy and expensive.

[0024] In view of this, the present application provides a blowing adjustment structure and adjustment method for a rudder and an aircraft, as follows Figure 1-Figure 7 The technical solution disclosed in the embodiments of the present application is described.

[0025] The blowing adjustment structure includes an air inlet cylinder 100 and a rotating body 200. Figure 2 , Figure 5 As shown, the air intake cylinder 100 is provided with an air flow gate 110, and the gas is input from the air supply pipeline into the air intake cylinder 100, and then output through the air flow gate 110. Specifically, the air flow gate 110 can be an opening of any shape.

[0026] The rotating body 200 is at least partially rotatably connected to the air inlet cylinder 100. Specifically, the rotating body 200 can be rotatable relative to the air inlet cylinder 100 as a whole, or only partially rotatable relative to the air inlet cylinder 100. The rotating body 200 includes a first chamber 210 and a second chamber 220, and the first chamber 210 and the second chamber 220 are respectively provided with a first air inlet 211 and a second air inlet 221, and the first air inlet 211 and the second air inlet 221 are respectively connected to the air flow gate 110. Gas can be blown into the first air inlet 211 and / or the second air inlet 221 from the air flow gate 110 to enter the first chamber 210 and the second chamber 220. Among them, the first chamber 210 and the second chamber 220 are gas flow channels independent of each other. The first chamber 210 and the second chamber 220 can be connected as a whole, or set separately.

[0027] Furthermore, the rotating body 200 is connected to the rudder. When the aircraft pilot turns the rudder to adjust the deflection angle of the aircraft, the rotating body 200 will rotate relative to the air inlet cylinder 100. At this time, the area of ​​the airflow gate 110 connected with the first air inlet 211 and the second air inlet 221 will also change with the rotation of the rotating body 200. When the rudder is rotated to a certain angle, the airflow can be blown from the airflow gate 110 through the first air inlet 211 and the second air inlet 221 into the first chamber 210 and the second chamber 220, and blown out through the first air outlet 212 and the second air outlet 222 of the first chamber 210 and the second chamber 220 to the corresponding air blowing controller. Correspondingly, the larger the area of ​​the first air inlet 211 connected to the airflow gate 110, the smaller the area of ​​the second air inlet 221 connected to the airflow gate 110, and the larger the amount of gas blown into the first chamber 210, the smaller the amount of gas blown into the second chamber 220, and vice versa.

[0028] In some embodiments, the opening area and opening shape of the first air inlet 211 and the second air inlet 221 can be set according to the air supply demand of the aircraft, and are not limited here.

[0029] In some embodiments, the deflection angle of the rudder may be the same as or different from the deflection angle of the rotating body 200. On aircraft with different air supply requirements, the deflection angle of the rudder and the corresponding relationship between the areas connected between the first air inlet 211, the second air inlet 221 and the airflow gate 110 may be set as needed, and are not limited here.

[0030] In addition, the embodiments of the present application do not limit the configuration or number of the airflow gate 110. Exemplarily, the airflow gate 110 can be two separated from each other, and the two airflow gates 110 correspond to the first air inlet 211 and the second air inlet 221 respectively. By driving the rotating body 200 through the rudder, the flow area of ​​the channel composed of the first air inlet 211 and one of the airflow gates 110 can be adjusted accordingly, and the flow area of ​​the channel composed of the second air inlet 221 and the other airflow gate 110 can be adjusted. It should be understood that in this example, the airflow gate 110 is set at two separated ones, and its opening area can be set smaller. Compared with setting an airflow gate 110 with a larger opening area, the strength of the corresponding part on the rotating body 200 can be improved, and the damage resistance performance can be improved.

[0031] In a more specific embodiment, two separated air flow gates 110 can be arranged between the first air inlet 211 and the second air inlet 221. When the rotating body 200 rotates, when the flow area of ​​the channel formed by one air inlet (for example, the first air inlet 211) and one of the air flow gates 110 increases, the flow area of ​​the channel formed by the other air inlet (for example, the second air inlet 221) and the other air flow gate 110 decreases accordingly.

[0032] The air blowing controller refers to a device or structure used to supply air in an aircraft, which can flow air to the tail surface of the aircraft to balance the aircraft's steering. In some embodiments, the air blowing controllers corresponding to the first chamber 210 and the second chamber 220 should be set in different positions. For example, the air in the first chamber 210 is blown into the air blowing controller on the left, and the air in the second chamber 220 is blown into the air blowing controller on the right.

[0033] The rotating body 200 is connected to the rudder, so that the blowing adjustment structure can have the ability to adapt. When the rudder is deflected, the rotating body 200 rotates accordingly, thereby automatically adjusting the connection area between the airflow gate 110 and the first air inlet 211 and the second air inlet 221, and then adjusting the amount of gas blown into different first chambers 210 and second chambers 220. The structure is simple and does not require additional control means. The blowing adjustment structure can change automatically according to the change of the rudder. In application scenarios such as flight or navigation, the airflow distribution can be adjusted in real time according to the change of the driving direction, so that the adjustment of the airflow is coordinated with the action of the rudder, the stability of the blowing adjustment process is optimized, and the problems such as airflow instability caused by the change of direction are effectively reduced. In addition, compared with traditional electromagnetic valves, the structural component greatly reduces the weight of the aircraft. At the same time, it also has the advantage of low price, saving the manufacturing and production costs of the aircraft.

[0034] In some embodiments, the rotating body 200 and the air inlet cylinder 100 can be rotatably connected in a variety of ways. Specifically, a sleeve 230 can be provided on the rotating body 200, and the sleeve 230 is sleeved on the air inlet cylinder 100, so that the rotating body 200 can rotate relative to the air inlet cylinder 100. By rotatably connecting the rotating body 200 and the air inlet cylinder 100 by sleeve 230, the flow channel of the air flow can be completely closed, which greatly improves the air tightness of the blowing adjustment structure, avoids gas escape, and reduces the problem of blowing efficiency.

[0035] In some embodiments, the rotating body 200 may further include a partition rotatably connected to the air inlet cylinder 100. The partition is connected to the rudder. When the rudder rotates, the partition is driven to rotate together, and the other parts of the rotating body 200 remain stationary. The partition is set at the connection between the first air inlet 211 and the second air inlet 221 and the air flow gate 110. By rotating the partition, the size of the opening area of ​​the first air inlet 211 and the second air inlet 221 connected to the air flow gate 110 can be adjusted, and then the amount of gas blown into the first chamber 210 and the second chamber 220 can be adjusted. By setting a rotatable partition to adjust the amount of gas blown into the first chamber 210 and the second chamber 220, the rest of the rotating body 200 can be kept stationary, and only the partition is moved, which greatly reduces the rotation space of the rotating body 200 inside the aircraft, avoids unnecessary interference between the blowing adjustment structure and the other components inside the aircraft, saves space, and improves the space utilization rate inside the aircraft. Furthermore, by moving only the partition plate with different openings, it is also beneficial to improve the sealing effect of gas circulation and prevent gas escape.

[0036] In some embodiments, when the rotating body 200 is sleeved on the air intake cylinder 100 through the sleeve 230, the sealing performance between the sleeve 230 and the air intake cylinder 100 can be improved by a sealing sleeve. The sealing sleeve needs to have a low friction resistance to reduce the friction resistance when the rotating body 200 rotates relative to the air intake cylinder 100. Exemplarily, the sealing sleeve can be polytetrafluoroethylene or a similar non-metallic material that is wear-resistant and has certain self-lubricating properties.

[0037] By providing a sealing sleeve, the sealing performance between the rotating body 200 and the air intake cylinder 100 can be further improved, thereby avoiding excessive loss of gas during the flow process and reducing the gas utilization efficiency.

[0038] In some embodiments, the first air inlet 211 and the second air inlet 221 have the same area. When the rudder has the same rotation angle to both sides, the first air inlet 211 and the second air inlet 221 have the same area, which can make it easier to process and produce the components. In addition, since the airflow gate 110 is opened on the air inlet cylinder 100, if the airflow gate 110 is too large, it will affect the inherent strength of the air inlet cylinder 100 components, and too large an opening will also more easily lead to gas loss. If the opening of the airflow gate 110 is too small, the gas supply of the first air inlet 211 and the second air inlet 221 cannot be met. Therefore, in order to ensure a certain fault tolerance during the rotation process, the area of ​​the airflow gate 110 can be slightly larger than the first air inlet 211 and the second air inlet 221. Specifically, the opening area of ​​the airflow gate 110 is R1, and the opening areas of the first air inlet 211 and the second air inlet 221 are R2, 1 <R2:R1<1.5。

[0039] By setting reasonable opening areas of the airflow gate 110 and the first air inlet 211 and the second air inlet 221, the strength of the component itself can be increased as much as possible, other flow losses can be reduced, and the blowing efficiency can be improved.

[0040] In some embodiments, the rotating body 200 further includes an output connector 240. The output connector 240 can be used to connect the rotating body 200 to the blowing controller. The output connector 240 includes a first output channel 241 and a second output channel 242. The first output channel 241 is connected to the first gas outlet 212, and the second output channel 242 is connected to the second gas outlet 222. The gas can flow from the first chamber 210 and the second chamber 220 into the first output channel 241 and the second output channel 242, respectively, and then flow into the corresponding blowing controller.

[0041] By setting the output connector 240, the rotating body 200 can be more conveniently connected to the blowing controllers of different models and specifications, thereby increasing the adaptability of the rotating body 200 to connect to different blowing controllers. In addition, setting the output connector 240 can also facilitate the replacement and maintenance of the rotating body 200 or the blowing controller.

[0042] In some embodiments, the first output channel 241 and the second output channel 242 may have various structures and shapes. Specifically, the cross-sectional shape of the first output channel 241 and the second output channel 242 may be circular.

[0043] The first output channel 241 and the second output channel 242 are provided with circular cross sections, so that the edges and corners of the output channels can be reduced, and when the wind flows through, local eddies and turbulence will not be generated, so the air flow resistance is reduced, and the gas can flow out more easily. In addition, under the same area, the circumference of the circle is the smallest, which is more convenient for processing and occupies less space.

[0044] In some embodiments, Figure 2 , 5 As shown in Figure 6, the first output channel 241 has a third air inlet 243, and the second output channel 242 has a fourth air inlet 244. Among them, the third air inlet 243 is connected to the first air outlet 212, and the opening area of ​​the third air inlet 243 is smaller than the opening area of ​​the first air outlet 212; the fourth air inlet 244 is connected to the second air outlet 222, and the opening area of ​​the fourth air inlet 244 is smaller than the opening area of ​​the second air outlet 222. At this time, when the gas flows out from the first air outlet 212 to the third air inlet 243, or flows out from the second air outlet 222 to the fourth air inlet 244, the gas flows in from the larger inlet and flows out from the smaller outlet. In the process of gas flow, according to the Bernoulli equation, when the gas flows in from the larger inlet and flows out from the smaller outlet, the flow rate of the gas can be accelerated, its kinetic energy can be increased, and the flow of the gas can be promoted, which is beneficial to the air flow control of the blowing controller, such as improving the mass flow rate of the high-speed jet.

[0045] In some embodiments, the perpendicular line of the plane where the first air inlet 211 is located is at least partially tangent to the side wall of the first chamber 210, and the perpendicular line of the plane where the second air inlet 221 is located is at least partially tangent to the side wall of the second chamber 220 so that the airflow is blown out in a spiral shape. At this time, when the gas enters the first chamber 210 or the second chamber 220, it does not directly collide with the side wall of the first chamber 210 or the second chamber 220, causing unnecessary consumption of energy, but forms a spiral airflow through its tangential component, which greatly reduces the flow loss of the airflow and improves the flow efficiency and flow speed of the airflow.

[0046] In some embodiments, the air inlet 100 includes a first airflow gate and a second airflow gate. Among them, the first airflow gate and the second airflow gate are arranged oppositely on the air inlet 100, the first airflow gate is connected to the first air inlet 211, and the second airflow gate is connected to the second air inlet 221. Exemplarily, when the first airflow gate and the second airflow gate are respectively arranged on opposite sides of the air inlet 100, the first chamber 210 and the second chamber 220 on the rotating body 200 are arranged correspondingly to the first airflow gate and the second airflow gate, and when the first chamber 210 is to supply air to the blowing controller on the left, the second chamber 220 is to supply air to the blowing controller on the right. On the one hand, by setting the first airflow gate and the second airflow gate separately, the air supply path can be shortened, the positions of the first chamber 210 and the second chamber 220 can be set adaptively, and the flexibility of the chamber position setting can be enhanced. In addition, the separate airflow gate 110 can reduce the area of ​​a single airflow gate 110 and improve the strength of the air inlet 100 itself.

[0047] In some embodiments, the projection shapes of the openings of the first air inlet 211 , the second air inlet 221 , and the air flow gate 110 are configured to have a smooth transition between any two sides.

[0048] Setting a smoothly transitioned opening shape can reduce the edges and corners of the airflow through the outlet. When the wind flows through, no local eddy currents and turbulence will be generated, which will reduce airflow resistance, facilitate gas outflow, and reduce gas loss.

[0049] The present application also provides an air blowing adjustment method for a rudder, which is performed based on an air blowing adjustment structure for a rudder. The method comprises:

[0050] Step 710, determining the heading change of the aircraft.

[0051] In some embodiments, step 710 may be performed by a pilot or operator of the aircraft. When the aircraft needs to turn, the pilot or operator needs to determine the heading change of the aircraft, and based on the heading change of the aircraft, determine the direction and angle in which the rudder needs to be turned.

[0052] Step 720, according to the change of the heading of the aircraft, the rudder is rotated to drive the rotating body 200 to rotate relative to the air inlet cylinder 100 to adjust the flow of gas blown into the two sides of the rudder.

[0053] In step 720, the pilot or operator of the aircraft rotates the rudder according to the direction and angle of the rudder determined in step 710. According to the above description of the air blowing adjustment structure, the rudder is connected to the rotating body 200, and the rotating body 200 is rotatably connected to the air inlet cylinder 100. When the rudder is deflected, the rotating body 200 rotates relative to the air inlet cylinder 100, thereby adjusting the opening area of ​​the first air inlet 211 and the second air inlet 221 connected to the air flow gate 110. For the specific description of the air blowing adjustment structure, please refer to the corresponding description in the specification, which will not be repeated here.

[0054] In some embodiments, the present application also provides an aircraft, the aforementioned aircraft comprising the aforementioned air blowing adjustment structure for a rudder.

[0055] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0056] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
