Description

Technical Field

[0001] This invention relates to the technical field of aircraft tires, and in particular to an aircraft tire structure and manufacturing process with uniformly distributed static electricity. Background Technology

[0002] During flight and landing, aircraft generate high levels of static electricity. This static electricity is typically discharged through discharge brushes to prevent the accumulation of high-energy electrical charges on the aircraft. During landing, static electricity on the fuselage is conducted to the aircraft tires via the landing gear. The high conductivity of the aircraft tires effectively dissipates any residual charge on the aircraft the moment the landing gear contacts the ground.

[0003] In existing technologies, carbon nanotubes are typically used to replace carbon black in tire raw materials to improve tire conductivity. For example, Chinese invention patent CN113929989A discloses a composition, compound, preparation method, and tire. Furthermore, the metallic radial fibers in tires can also improve conductivity to some extent. However, the amount of carbon nanotubes added to tire rubber is relatively small and cannot effectively connect into a unified conductive network structure. The metallic radial fibers also have a layered structure, and the combination of metallic radial fibers and carbon nanotubes cannot form a unified conductive network structure. This results in localized static electricity on the aircraft tires not being able to conduct to other parts during flight, leading to potential differences on the tires. When this potential difference reaches a point where the tire's resistance breaks down, a breakdown discharge occurs, generating electric sparks and posing a danger. Therefore, a static-balanced aircraft tire is needed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an aircraft tire structure and manufacturing process that forms an integral conductive mesh structure in the tire, so as to make the static electricity distribution uniform, avoid breakdown discharge and electric sparks, and reduce dangerous static electricity uniform distribution.

[0005] This invention discloses an electrostatically uniformly distributed aircraft tire structure, comprising an outer layer, an inner layer, and a radial layer. The inner layer is disposed inside the outer layer, and the radial layer is disposed between the outer and inner layers, connected through the mesh holes of the radial layer. The structure also includes a conductive mesh and conductive filaments. Carbon nanotubes are added to the outer and inner layers. The conductive mesh is disposed on the radial layer and is woven from conductive wires into a mesh structure. Numerous conductive filaments are disposed on the conductive mesh, and these filaments are conductive wires. Multiple conductive filaments are dispersed and extend into the outer and inner layers. The conductive filaments are curved and spiral-shaped, with multiple conductive filaments in contact with carbon nanotube raw materials. The meridional layer, conductive mesh, and conductive filaments, combined with the carbon nanotube raw materials, form an overall conductive mesh structure. The carbon nanotube raw materials in the outer and inner layers are interconnected through the meridional layer, conductive mesh, and a large number of conductive filaments, forming an overall conductive mesh structure that covers the outer and inner layers. This conducts all local static electricity of the aircraft tire, making the static electricity distribution of the aircraft tire uniform, avoiding the formation of potential differences in the tire, avoiding breakdown discharge and electric sparks, and reducing danger.

[0006] Preferably, the weight ratio of carbon nanotube raw material to rubber raw material is 5-30:100; through the above ratio, the electrical conductivity is improved while ensuring the wear resistance, elasticity and other mechanical properties of the aircraft tire, and cost is taken into account.

[0007] Preferably, it also includes anti-slip patterns, with a large number of anti-slip patterns evenly arranged laterally on the outer wheel surface. One side of the anti-slip pattern has a windward surface that is parallel to the radial direction of the tire, and the other side of the anti-slip pattern has a windward guide surface that is inclined to the windward surface. By setting windward and windward surfaces on both sides of the anti-slip pattern, the force of air acting on the windward surface of the anti-slip pattern is greater than the force acting on the windward surface after the tire extends out of the aircraft. The unbalanced force causes the tire to rotate. The rotating tire makes full contact with the air, reducing the uneven static electricity generated by air friction. By adjusting the installation direction of the tire, the direction of tire rotation can be made to follow the runway, thereby reducing the relative friction between the aircraft tire and the runway and improving practicality.

[0008] Preferably, it also includes multiple annular grooves, with multiple annular grooves provided on the multiple anti-slip patterns, and the multiple annular grooves are coaxial with the tire; by providing multiple annular grooves, the lateral friction of the tire can be improved.

[0009] Preferably, the conductive wires of the conductive mesh and conductive filaments are carbon fiber filaments; by using carbon fiber filaments as conductive wires, the conductivity is high, the weight is light, and the performance of carbon fiber filaments is similar to that of carbon nanotubes, which can make the overall conductive mesh structure have uniform resistance and good practicality.

[0010] A manufacturing process for aircraft tires with uniform electrostatic distribution includes production equipment and a production method. The production equipment includes a lower mold, a feeding pipe, an upper mold, an inner mold, an insulating tube, a battery cell, and multiple conductive sheets. The lower mold has a forming chamber that shapes the outer surface of the tire. The feeding pipe is mounted on the lower mold, and its output end is connected to the forming chamber. The lower mold has a pick-and-place port that is connected to the forming chamber. The upper mold is mounted on the pick-and-place port. The inner mold is mounted on the lower end face of the upper mold and is suspended within the forming chamber of the lower mold. The inner mold shapes the inner cavity of the aircraft tire. The insulating tube is rotatably mounted on the upper mold, with its lower end extending into the inner mold. A battery cell is located inside the insulating tube. Conductive sheets are installed at the lower end of the insulating tube. Multiple conductive sheets are electrically connected to the battery core. Multiple conductive sheets pass through the inner mold and extend into the molding chamber of the lower mold. Multiple conductive sheets support the conductive mesh arranged in the molding chambers of the inner and lower molds. The conductive mesh is set between the inner wall of the molding chamber of the lower mold and the inner mold, and the multiple conductive sheets are electrically connected to the conductive mesh. When the battery core is energized, it conducts electricity to the conductive mesh through the multiple conductive sheets, causing the multiple conductive strips to separate from each other due to the same charge repulsion. Rotating the insulating tube rolls up the multiple conductive sheets, causing the multiple conductive sheets to detach from the conductive mesh. Rubber raw material is fed into the lower mold through the feeding pipe. The inner wall of the molding chamber of the lower mold shapes the outer wall of the tire, and the inner mold shapes the inner cavity of the tire.

[0011] Preferably, it also includes a bearing and a protrusion, with the middle part of the insulating tube rotatably connected to the upper mold via the bearing; the bearing facilitates smooth rotation of the insulating tube, and the protrusion facilitates clamping and rotation of the insulating tube.

[0012] Preferably, the production method includes:

[0013] S1, using the above-mentioned production equipment, prepare the outer composite A of the aircraft tire containing conductive mesh and conductive filaments;

[0014] S2, using the above-mentioned production equipment to prepare an inner layer composite B of an aircraft tire, including a conductive mesh and a radial layer;

[0015] S3, using conventional production equipment to bond composite A to composite B.

[0016] Preferably, S1 specifically involves: firstly, a coating that facilitates demolding is applied to the outer wall of the first inner mold and the inner wall of the molding cavity of the first lower mold; then, a conductive mesh is fitted onto the outer wall of the first inner mold, and the conductive mesh is brought into contact with multiple first conductive sheets; the first upper mold is installed onto the first lower mold; the first battery cell is connected to the electrode; and the conductive filaments of the conductive mesh are energized through the multiple first conductive sheets, causing a large number of conductive filaments to repel each other after carrying the same charge, thus separating from each other; the insulating tube is rotated by the protrusion, causing the multiple first conductive sheets to be rolled up at the lower end of the first insulating tube, thus separating the multiple first conductive sheets from the conductive mesh; and tire raw material is slowly added to the molding cavity of the first lower mold through the first feeding tube. After the tire raw material solidifies, multiple conductive filaments are evenly arranged in the outer layer, and the multiple conductive filaments are fully connected with the carbon nanotube raw material in the outer layer to form an overall conductive mesh structure.

[0017] Preferably, S2 specifically involves: firstly, a coating for easy demolding is applied to the outer wall of the second inner mold and the inner wall of the molding chamber of the second lower mold; the meridional layer is fitted onto the inner wall of the molding chamber of the second lower mold; the conductive mesh is fitted onto the inner side of the meridional layer; the second upper mold is installed onto the second lower mold, so that the conductive mesh contacts multiple second conductive sheets; the second battery cell is connected to the electrode; and the conductive filaments of the conductive mesh are energized through multiple second conductive sheets, causing a large number of second conductive filaments to repel each other after carrying the same charge, thus separating them; the second insulating tube is rotated by the second protrusion, causing multiple second conductive sheets to roll up to the lower end of the second insulating tube, thus separating the multiple second conductive sheets from the conductive mesh; and tire raw material is slowly added to the molding chamber of the second lower mold through the feeding pipe. After the tire raw material solidifies, multiple conductive filaments are evenly arranged in the inner layer, and the multiple conductive filaments are fully connected with the carbon nanotube raw material in the inner layer to form an overall conductive mesh structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the carbon nanotube raw materials in the outer and inner layers are interconnected by the meridional layer, the conductive mesh and a large number of conductive filaments to form an overall conductive mesh structure that covers the outer and inner layers, thereby guiding all local static electricity of the aircraft tire to the whole, making the static electricity distribution of the aircraft tire uniform, avoiding the formation of potential difference in the tire, avoiding breakdown discharge and electric sparks, and reducing danger.

[0025] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0026] Example 1

[0027] A uniformly electrostatically distributed aircraft tire structure and manufacturing process includes an outer layer 1, an inner layer 2, and a meridian layer 3. The inner layer 2 is disposed inside the outer layer 1, and the meridian layer 3 is disposed between the outer layer 1 and the inner layer 2. The outer layer 1 and the inner layer 2 are connected through the mesh holes of the meridian layer 3. The tire also includes a conductive mesh 4 and conductive filaments 5. Carbon nanotubes are added to the outer layer 1 and the inner layer 2. The conductive mesh 4 is disposed on the meridian layer 3 and is woven from conductive wires into a mesh structure. A large number of conductive filaments 5 are disposed on the conductive mesh 4. The conductive filaments 5 are conductive wires, and multiple conductive filaments 5 are dispersed and extend into the outer layer 1 and the inner layer 2. The multiple conductive filaments 5 are curved and spiral-shaped and in contact with the carbon nanotubes. The meridian layer 3, the conductive mesh 4, and the conductive filaments 5, combined with the carbon nanotubes, form an overall conductive mesh structure. The weight ratio of the carbon nanotubes to the rubber material is 5-30:100. The conductive filaments of the conductive mesh 4 and the conductive filaments 5 are carbon fiber filaments.

[0028] The carbon nanotube materials in the outer layer 1 and inner layer 2 are interconnected by the meridional layer 3, the conductive mesh 4, and a large number of conductive filaments 5, forming an overall conductive mesh structure that covers the outer layer 1 and inner layer 2. This conducts all the local static electricity of the aircraft tire, making the static electricity distribution of the aircraft tire uniform, avoiding the formation of potential differences in the tire, avoiding breakdown discharge and electric sparks, and reducing danger. Through the above proportional relationship, the conductivity is improved while ensuring the wear resistance, elasticity and other mechanical properties of the aircraft tire, and the cost is taken into account. By using carbon fiber filaments as conductive filaments, the conductivity is high and the weight is light. Moreover, the properties of carbon fiber filaments are similar to those of carbon nanotubes, which can make the overall conductive mesh structure have uniform resistance and good practicality.

[0029] Example 2

[0030] A uniformly electrostatically distributed aircraft tire structure and manufacturing process includes an outer layer 1, an inner layer 2, and a radial layer 3. The inner layer 2 is disposed inside the outer layer 1, and the radial layer 3 is disposed between the outer layer 1 and the inner layer 2. The outer layer 1 and the inner layer 2 are connected through the mesh holes of the radial layer 3. The tire also includes a conductive mesh 4 and conductive filaments 5. Carbon nanotubes are added to the outer layer 1 and the inner layer 2. The conductive mesh 4 is disposed on the radial layer 3 and is woven from conductive wires into a mesh structure. A large number of conductive filaments 5 are disposed on the conductive mesh 4. The conductive filaments 5 are conductive wires, and multiple conductive filaments 5 extend dispersedly into the outer layer 3. In the outer layer 1 and the inner layer 2, multiple conductive filaments 5 are bent into a spiral shape and are in contact with carbon nanotube raw materials. The meridional layer 3, conductive mesh 4, and conductive filaments 5, together with the carbon nanotube raw materials, form an overall conductive mesh structure. It also includes anti-slip patterns 6, with a large number of anti-slip patterns 6 evenly arranged laterally on the outer wheel surface of the outer layer 1. One side of the anti-slip pattern 6 is provided with a windward surface that is parallel to the radial direction of the tire, and the other side of the anti-slip pattern 6 is provided with a windward surface that is inclined to the windward surface. It also includes multiple annular grooves 7, with multiple annular grooves 7 provided on multiple anti-slip patterns 6, and multiple annular grooves 7 are coaxial with the tire.

[0031] By setting windward and guiding surfaces on both sides of the anti-slip treads 6, the force exerted by air on the windward surface of the anti-slip treads 6 is greater than that on the guiding surface after the tire extends out of the aircraft. This unbalanced force causes the tire to rotate, and the rotating tire makes full contact with the air, reducing the uneven static electricity generated by air friction. By adjusting the installation direction of the tire, the direction of tire rotation can be aligned with the runway, thereby reducing the relative friction between the aircraft tire and the runway and improving practicality. The lateral friction of the tire can be increased by setting multiple annular grooves 7.

[0032] Example 3

[0033] The production equipment includes a lower mold 8, a feeding pipe 9, an upper mold 10, an inner mold 11, an insulating tube 12, a battery cell 13, and multiple conductive sheets 14. The lower mold 8 has a forming chamber inside, which shapes the outer surface of the tire. The feeding pipe 9 is installed on the lower mold 8, and its output end communicates with the forming chamber. The lower mold 8 has a pick-and-place port, which communicates with the forming chamber. The upper mold 10 is installed on the pick-and-place port. The inner mold 11 is installed on the lower end face of the upper mold 10 and is suspended within the forming chamber of the lower mold 8. The inner mold 11 shapes the inner cavity of the aircraft tire. The insulating tube 12 rotates... The insulating tube 12 is mounted on the upper mold 10. The lower end of the insulating tube 12 extends into the inner mold 11. The inside of the insulating tube 12 is equipped with a battery cell 13. Multiple conductive sheets 14 are mounted on the lower end of the insulating tube 12 and are electrically connected to the battery cell 13. The multiple conductive sheets 14 pass through the inner mold 11 and extend into the molding chamber of the lower mold 8. The multiple conductive sheets 14 support the conductive mesh 4 in the molding chambers of the inner mold 11 and the lower mold 8. The device also includes a bearing 15, and the middle part of the insulating tube 12 is rotatably connected to the upper mold 10 through the bearing 15. The device also includes a protrusion 16, which is disposed on the upper outer wall of the insulating tube 12.

[0034] The conductive mesh 4 is set between the inner wall of the molding cavity of the lower mold 8 and the inner mold 11, and multiple conductive sheets 14 are electrically connected to the conductive mesh 4. The battery core 13 is energized, and the multiple conductive sheets 14 conduct electricity to the conductive mesh 4, so that multiple conductive filaments 5 are separated from each other due to repulsion caused by the same charge. The rotating insulating tube 12 winds up the multiple conductive sheets 14, so that the multiple conductive sheets 14 are separated from the conductive mesh 4. Rubber raw material is fed into the lower mold 8 through the feeding tube 9. The inner wall of the molding cavity of the lower mold 8 shapes the outer wall of the tire, and the inner mold 11 shapes the inner cavity of the tire. The bearing 15 is set to facilitate the smooth rotation of the insulating tube 12, and the protrusion 16 is set to facilitate the clamping of the rotating insulating tube 12.

[0035] like Figure 4 and Figure 5As shown, the present invention discloses an aircraft tire structure and manufacturing process with uniform electrostatic distribution. During operation, a coating for easy demolding is first applied to the outer wall of the first inner mold 11 and the inner wall of the molding chamber of the first lower mold 8. A conductive mesh 4 is then fitted onto the outer wall of the first inner mold 11, and the conductive mesh 4 is brought into contact with multiple first conductive sheets 14. The first upper mold 10 is then installed onto the first lower mold 8. The first battery cell 13 is connected to the electrode. Electricity is supplied to the conductive filaments 5 of the conductive mesh 4 through the multiple first conductive sheets 14, causing a large number of conductive filaments 5 to carry... Like charges repel each other, thus separating them. The insulating tube 12 is rotated by the protrusion 16, causing multiple first conductive sheets 14 to be wound around the lower end of the first insulating tube 12, detaching the multiple first conductive sheets 14 from the conductive mesh 4. Tire material is then slowly added to the molding chamber of the first lower mold 8 through the first feeding tube 9. After the tire material solidifies, multiple conductive filaments 5 are evenly arranged in the outer layer 1, and the multiple conductive filaments 5 are fully connected with the carbon nanotube material in the outer layer 1, forming an overall conductive mesh structure. Next, in the second inner mold 11... A coating for easy demolding is provided on the outer wall of the upper mold and the inner wall of the molding chamber of the lower mold 8. The meridional layer 3 is fitted onto the inner wall of the molding chamber of the lower mold 8, and the conductive mesh 4 is fitted onto the inner side of the meridional layer 3. The upper mold 10 is installed onto the lower mold 8, so that the conductive mesh 4 contacts multiple second conductive sheets 14. The second battery cell 13 is connected to the electrode, and the conductive filaments 5 of the conductive mesh 4 are energized through the multiple second conductive sheets 14. This causes a large number of second conductive filaments 5 to repel each other after carrying the same charge, thus separating them. The two protrusions 16 rotate the second insulating tube 12, causing multiple second conductive sheets 14 to be rolled up at the lower end of the second insulating tube 12, thus separating the multiple second conductive sheets 14 from the conductive mesh 4. Tire raw material is slowly added into the molding chamber of the second lower mold 8 through the feeding tube 9. After the tire raw material solidifies, multiple conductive filaments 5 are evenly arranged in the inner layer 2, and the multiple conductive filaments 5 are fully connected with the carbon nanotube raw material in the inner layer 2 to form an overall conductive mesh structure. Then, the composite A is bonded to the composite B using conventional production equipment.
