Description

Technical Field

[0001] The invention relates to the technical field of tandem unmanned helicopters, in particular to an anti-static and anti-vibration fuel tank for helicopters. Background Art

[0002] In recent years, the requirements for the flight stability of medium and large fuel-powered unmanned helicopters have become increasingly higher, especially in the case of large maneuvering flights, because unmanned helicopters are equipped with flight control and gyro systems that are sensitive to flight attitude and vibration, which are very important for judging flight attitude and vibration. Although there are many factors that affect the stability of an aircraft, including engine vibration, rotor flapping and swinging vibration, etc., here we start with the fuel sloshing in the fuel tank to solve one of the factors in order to achieve the goal of overall optimization. At present, many medium and large unmanned helicopters are equipped with large fuel tanks in order to maintain long flight time. The larger the fuel tank, the more fuel it can hold, which will cause gaps in the fuel during use. The appearance of gaps will only intensify the fuel sloshing back and forth inside the tank. This sloshing of fuel will constantly change the center of gravity of the entire aircraft, and will also form inertia in a certain direction, which is very unfavorable to the stability of the flight attitude. In order to solve the above problems, many companies have adopted the method of adding multiple baffles inside the fuel tank, as well as the method of adding sponges. For the former, the measure of reducing fuel sloshing by adding baffles is effective, but this effect is based on quantity, which means that the baffles The more the number, the more obvious the anti-sway effect, but it will lead to complex overall manufacturing, increased weight and smaller space. If sponge is used as the stabilizing medium, the anti-sway effect is the best, but it is not advantageous in weight. After the sponge absorbs the oil, a lot of fuel is attached to the sponge and cannot be flowed out for use, causing the fuel to become dead weight. In addition, the sponge medium is easily corroded and aged under the immersion of fuel for a long time. There is a risk of blocking the fuel pipe when the sponge residue is removed for a long time. Therefore, considering all factors, the sponge may have the lowest energy efficiency ratio for fuel swing, unless a special sponge is developed to improve it. For normal design thinking, the anti-sway energy efficiency ratio of the partition is the best. However, at present, this type of anti-sway plate is basically designed as a straight plate, which has a good effect perpendicular to the direction of the anti-sway plate, but a weak effect in the direction parallel to the anti-sway plate. For this reason, an anti-static and anti-shock fuel tank for helicopters is proposed. Summary of the invention

[0041] The heating assembly is used for preheating the fuel tank 1. The heating assembly includes an air suction seat 15, a heating plate seat 16 and an air guide plate seat 17. The air suction seat 15 and the heating plate seat 16 are respectively provided with a turbofan and a heater. Figure 8 As shown, the turbofan is installed inside the suction seat 15, the heating plate seat 16 is mounted on the air inlet side of the suction seat 15 in a counter-engaging support, the heater is fixedly installed on the inner side of the heating plate seat 16, the heater is a PTC heating module, and the heating plates are evenly installed in parallel inside, the heating plate seat 16 and the suction seat 15 are installed and distributed in a close-fitting manner, the heating plate seat 16 and the suction seat 15 are fixedly installed on the rear part of the installation box seat 2 by bolts, and the air guide plate seat 17 is used for guiding and conveying hot air, as shown in the attached figure. Figure 8 As shown, there are two groups of air guide plate seats 17, and the two groups of air guide plate seats 17 are fixedly connected and installed on the air outlet sides of both sides of the rear of the air suction seat 15, and the air guide plate seats 17 are embedded and installed on the inner side of the slot set at the rear of the installation box seat 2, as shown in the attached Figure 7 As shown, in order to facilitate the connection and installation of the air guide plate seat 17, a plate seat installation groove is provided at the rear part of the installation box seat 2, and the inner side of the plate seat installation groove is an open structure.

The heating component can be disassembled and taken out as a whole only by removing the fastening bolt structure. The disassembly and assembly are convenient, which can effectively improve the convenience of maintenance and repair of the heating component.

[0042] As attached Figure 7As shown, air outlet slots 18 are evenly arranged on the sides of the air guide plate seat 17. In order to improve the heating effect, air collecting slots 19 are arranged on both sides of the interior of the mounting box seat 2. The air heated by the heating plate seat 16 is sucked in by the turbofan in the air suction seat 15, and the hot air is blown into the interior of the mounting box seat 2 through the air guide plate seat 17. The fuel tank 1 is heated by the hot air flowing into the interlayer chamber between the mounting box seat 2 and the fuel tank body 1. The structure is simple and the heating is efficient. In severe cold weather, the aircraft oil circuit can be quickly preheated and heated. Moreover, through the hot air heating, the heating structure has no direct contact with the fuel tank body 1, which greatly improves the working safety of the device. In order to improve the heating efficiency, the upper side of the air collecting slot 19 is set as a bevel surface, and the upper part of the air collecting slot 19 is evenly provided with exhaust slots 20.

[0043] Working principle or structural principle, during installation, the fuel tank body 1 is aligned and inserted into the interior of the installation box seat 2, and then the installation and tightening of the oil outlet interface 11 and the positioning notch 21 are completed. After completion, the oil supply pipeline and the electrostatic guide are connected and installed to complete the installation operation of the fuel tank body 1. When the aircraft is running, the oil in the fuel tank body 1 flows out through the oil outlet interface 11 to provide driving oil for the aircraft. When the aircraft changes its attitude, the oil in the fuel tank body 1 ripples. When the oil ripples, the multi-fold inner partition 4 blocks the oil in the fuel tank body 1. The folding direction of the inner partition 4 is perpendicular to the blocking surface of the adjacent inner partition 4, which can effectively reduce the oil ripples in the front and back and up and down directions, and avoid excessive ripples of the oil on the flight attitude of the aircraft. At the same time, the static electricity generated by the rippling of the oil is conducted through the inner partition 4, and then connected and guided by the conductive connecting piece 5 to the wire installation column 6. Finally, the static electricity is conducted to the upper part of the helicopter frame or the discharge brush through the electrostatic guide, so as to achieve rapid release and elimination of static electricity;

During preheating, the heating plate in the heating plate seat 16 and the turbofan in the air suction seat 15 work, and the turbofan in the air suction seat 15 sucks the air heated by the heating plate seat 16, and then blows the hot air into the interior of the mounting box seat 2 through the guidance of the air guide plate seat 17. The hot air is blown into the mounting box seat 2 through the air guide plate seats 17 on both sides. The hot air is gathered in the groove cavity 19 and is conducted to heat the fuel tank 1 in the mounting box seat 2, and then the hot air continues to circulate and is blown out from the exhaust slot 20 in a direction. The upper side of the air collecting groove cavity 19 is set as an inclined surface, so that the hot air blown out from the exhaust slot 20 is blown to the side of the fuel tank 1, thereby realizing secondary heating of the fuel tank 1. When disassembling the heating component, it is only necessary to loosen and remove the bolt structure on the upper part of the heating plate seat 16, and then the heating component can be disassembled and removed as a whole by pulling.
