Description

Technical Field

[0001] The invention belongs to the technical field of aircraft design, relates to aircraft antenna technology, and in particular to a vertical tail antenna capable of dissipating vibration energy. Background Art

[0002] The end of the vertical tail of the aircraft is far away from other equipment on the fuselage, has less electromagnetic interference, and is less blocked by the fuselage. It is an ideal antenna installation location, so many aircraft choose to install the antenna at the end of the vertical tail of the aircraft. However, the vertical tail of the aircraft is located at the rear of the fuselage, and the airflow blowing from the wings and fuselage is very turbulent. These turbulent airflows will force the vertical tail antenna to vibrate. In severe cases, the vertical tail antenna structure will be damaged, and even the vertical tail will be damaged, causing the aircraft to lose control and crash. In the face of the vibration of the vertical tail antenna caused by turbulence, the usual practice is to strengthen the structure of the vertical tail antenna so that the vertical tail antenna can withstand such vibration. Simply strengthening the structure and increasing the weight will reduce the performance of the aircraft. Moreover, after the vertical tail antenna withstands the vibration, it will transfer the vibration energy to the vertical tail and the fuselage. There are many precision equipment in the fuselage, and the vibration will cause the equipment performance to decline or even fail. In addition, the vibration will make the pilot feel tired and uncomfortable, reducing the pilot's driving level and bringing danger to the flight.

An adjusting block with a rear stator oil hole 10 is arranged in the mounting groove at the bottom of the stator 8. The oil hole of the adjusting block at the bottom of the rear stator 8 corresponds to the oil hole position of the adjusting block at the bottom of the front stator 7. The adjusting block is made of memory alloy. The front rotor 11 is sleeved in the heat dissipation tube 6, and the front rotor 11 is provided with a plurality of partitions with mounting grooves along the circumferential direction. The partitions of the front rotor 11 are inserted into a plurality of chambers of the front stator 7 one by one, and each chamber of the front stator 7 is divided into two sub-chambers. The partitions of the front rotor 11 are provided with The rear rotor 12 is mounted in the heat dissipation tube 6, and the rear rotor 12 is provided with a plurality of partitions with mounting grooves along the circumferential direction. The partitions of the rear rotor 12 are inserted into the plurality of chambers of the rear stator 8 one by one, and each chamber of the rear stator 8 is divided into two sub-chambers. The partitions of the rear rotor 12 are provided with an adjusting block for installing the rear rotor oil hole 14. The front rotor 11, the rear rotor 12, the front stator 7, and the rear stator 8 are provided with a connection for installing the adjusting block. The front rotor 11 and the rear rotor 12 are connected to the front stator 7 and the rear stator 8 through the connecting shaft 15 and are fixed by the connecting shaft nut 17. A plurality of corresponding elastic shaft mounting holes are arranged around the central shaft holes of the front rotor 11, the rear rotor 12, the front stator 7 and the rear stator 8. The elastic shaft is arranged in the elastic shaft mounting hole. The elastic shaft 16 connects the front stator 7, the rear stator 8, the front rotor 11 and the rear rotor 12. The elastic shaft 16 is made of memory alloy.

[0034] Among them, the front stator oil hole 9 is installed at the bottom of the front stator 7 by welding, and the rear stator oil hole 10 is installed at the bottom of the rear stator 8 by welding. The front rotor 11 is sleeved in the heat dissipation tube 6, and the rear rotor 12 is sleeved in the heat dissipation tube 6. The front rotor 11 and the rear rotor 12 are connected to the front stator 7 and the rear stator 8 through the connecting shaft 15, and are fixed by the connecting shaft nut 17. The front rotor oil hole 13 is connected to the side wall of the front rotor 11 by welding, and the rear rotor oil hole 14 is connected to the side wall of the rear rotor 12 by welding. The reset spring 16 passes through the front stator 7 and the rear stator 8 and is fixed to the bottom of the front rotor 11 and the rear rotor 12 through the reset shaft nut 18.

[0035] The heat dissipation tube 6 is a round tube structure with a heat dissipation fin on the outer surface, which can be made of copper with good thermal conductivity. The heat dissipation tube 6 has lugs, which can be connected to the vertical tail 5 by bolts.

[0036] The front stator 7 and the rear stator 8 are evenly arranged with chambers along the circumference, and the chambers are filled with hydraulic oil. The chamber sector angle is controlled by the antenna vibration amplitude. The larger the antenna amplitude, the larger the chamber sector angle, and the smaller the antenna amplitude, the smaller the chamber sector angle. If the chamber sector angle is A, the front stator 7 and the rear stator 8 are displaced by A / 2, that is, half of the chamber of the front stator 7 faces half of the chamber of the rear stator 8. A through hole is left in the middle of the front stator 7 and the rear stator 8 for the connection shaft 15 and the reset spring 16 to pass through, and an opening is left at the bottom for installing the front stator oil hole 9 and the rear stator oil hole 10.

[0037] The front stator oil hole 9 and the rear stator oil hole 10 are made of memory alloy. When the vibration of the vertical tail antenna intensifies and the temperature of the hydraulic oil rises, the front stator oil hole 9, the rear stator oil hole 10, the front rotor oil hole 13, and the rear rotor oil hole 14 made of memory alloy expand, the opening becomes smaller, the oil hole of the rotary damper 2 becomes smaller and the damping becomes larger, which suppresses the vibration of the vertical tail antenna 1 while changing the vibration mode of the vertical tail antenna to avoid structural resonance.

[0038] The front rotor 11 and the rear rotor 12 are cylindrical structures with a chamber in the middle. The chamber sector angle is the same as that of the front stator 7 and the rear stator 8. The bottom is provided with through holes for installing the connecting shaft 15 and the reset spring 16, and the side wall is provided with openings for installing the front rotor oil hole 13 and the rear rotor oil hole 14. The front rotor 11 and the rear rotor 12 have ears, which can be connected to the vertical tail antenna 1 by bolts.

[0039] The front rotor oil hole 13 and the rear rotor oil hole 14 are made of memory alloy. When the vibration of the vertical tail antenna intensifies and the temperature of the hydraulic oil rises, the front rotor oil hole 13 and the rear rotor oil hole 14 made of memory alloy expand, the opening becomes smaller, the oil hole of the rotary damper 2 becomes smaller and the damping becomes larger, thereby suppressing the vibration of the vertical tail antenna 1, changing the vibration mode of the vertical tail antenna, and avoiding structural resonance.

[0040] The connecting shaft 15 connects the front stator 7 , the rear stator 8 , the front rotor 11 , and the rear rotor 12 in series, and fixes them together via a connecting shaft nut 17 .

[0041] The spring shaft 16 is arranged around the connecting shaft 15 and is made of memory alloy, and uses the ductility of the memory alloy to provide a reset elastic force for the front rotor 11 and the rear rotor 12. When the vibration of the vertical tail antenna intensifies and the temperature of the hydraulic oil rises, the spring shaft 16 made of the memory alloy expands and relaxes, and the reset elastic force of the spring shaft on the front rotor 11 and the rear rotor 12 becomes smaller, and the rotation amplitude of the front rotor 11 and the rear rotor 12 becomes larger, increasing the working stroke, accelerating the temperature rise of the hydraulic oil, and accelerating the dissipation of vibration energy.

[0042] The heat dissipation tube 6 is a cylindrical structure, and a heat dissipation fin is arranged on the outer surface. It is made of copper with good heat dissipation performance. The front stator 7 and the rear stator 8 are installed in the heat dissipation tube, and interference fit and welding reinforcement are adopted. The front stator 7 and the rear stator 8 are evenly arranged with chambers along the circumference. The chamber sector angle is designed according to the vibration amplitude of the vertical tail antenna 1. The larger the vibration amplitude, the larger the chamber sector angle, and the smaller the vibration amplitude, the smaller the chamber sector angle. The front stator 7 and the rear stator 8 are symmetrical in structure, and the chamber is offset by half, so that half of the chamber of the front stator 7 faces half of the chamber of the rear stator 8. When the vertical tail antenna 1 drives the front rotor 11 and the rear rotor 12 to vibrate, one side of the hydraulic oil in the chamber is pressurized, and the chamber can be divided into half a high-pressure chamber and half a low-pressure chamber. Since half of the chamber of the front stator 7 faces half of the chamber of the rear stator 8, that is, the high-pressure chamber of the front stator 7 faces the low-pressure chamber of the rear stator 8, and the low-pressure chamber of the front stator 7 faces the high-pressure chamber of the rear stator 8, the hydraulic oil flows from the high-pressure chamber to the low-pressure chamber through the front stator oil hole 9 and the rear stator oil hole 10. Similarly, the side walls of the front rotor 11 and the rear rotor 12 are equipped with oil holes, and the rotor side walls divide the stator chamber into half a high-pressure chamber and half a low-pressure chamber. The hydraulic oil can flow from the high-pressure chamber to the low-pressure chamber through the front rotor oil hole 13 and the rear rotor oil hole 14. The hydraulic oil is very viscous and will generate a lot of heat energy by friction when flowing through the oil hole. It can provide damping force to suppress the vibration of the vertical tail antenna 1 while dissipating the vibration capacity, and will not transmit the vibration to the vertical tail 5, which can improve the performance of the aircraft and flight safety. The oil hole of the present invention is made of memory alloy. When the vertical tail antenna 1 causes the hydraulic oil temperature to rise, the oil hole expands, causing the pores left by the oil hole to become smaller. The smaller pores will increase the resistance when the hydraulic oil passes through, so that the damping value of the rotary damper 2 becomes larger. The larger damping value can suppress the vibration of the vertical tail antenna 1, and at the same time change the vibration mode of the vertical tail antenna 1 to avoid structural resonance.

[0043] The front rotor 11, the rear rotor 12, the front stator 7, and the rear stator 8 are connected in series through the connecting shaft 15 and fixed by the connecting shaft nut 17. Through holes are left at the bottom of the front rotor 11, the rear rotor 12, the front stator 7, and the rear stator 8, and the reset spring 16 passes through the through holes at the bottom of the front rotor 11, the rear rotor 12, the front stator 7, and the rear stator 8 and is fixed by the reset spring nut 18. The reset spring 16 provides elastic force to reset the vertical tail antenna 1 to the neutral position, and controls the vibration stroke of the vertical tail antenna 1, and provides support for the vertical tail antenna 1 when the vibration is small. The reset spring 16 is made of memory alloy, which has good ductility and can be used as a spring. And when the hydraulic oil temperature rises, the reset spring 16 made of memory alloy expands and becomes longer, and the elastic force becomes smaller, so that the vibration stroke of the vertical tail antenna 1 becomes larger, and the stroke of the rotary damper 2 also becomes larger. The larger the stroke, the greater the working distance, and the greater the consumption of vibration energy, the faster the dissipation of vibration energy can be when the vertical tail antenna 1 vibrates violently.

[0044] The present invention utilizes a rotary damper to convert vibration energy into heat energy and dissipate it into the air, thereby reducing the vibration of the vertical tail antenna and improving aircraft performance and flight safety. Compared with common axial motion dampers, the rotary damper can amplify vibrations with a smaller motion stroke through multiple chambers, thereby solving the problem of low efficiency of the damper in vibrations with a smaller amplitude. The present invention uses a memory alloy to make an oil hole, and adjusts the size of the oil hole by the temperature of the hydraulic oil. When the vibration of the vertical tail antenna intensifies and the temperature of the hydraulic oil rises, the oil hole becomes smaller and the damping value of the damper becomes larger. The vibration of the vertical tail antenna can be suppressed by increasing the damping value, and the vibration mode of the vertical tail antenna can be changed to avoid structural resonance. The present invention uses a memory alloy to make a reset spring. When the vibration of the vertical tail antenna intensifies and the temperature of the hydraulic oil rises, the reset spring expands and relaxes, the reset elastic force becomes smaller, the rotation amplitude of the rotary damper becomes larger, the working stroke is increased, the temperature rise of the hydraulic oil is accelerated, and the dissipation of vibration energy is accelerated. The present invention has a clear principle, is easy to produce, has strong practicality, is easy to promote and apply, and has great value.
