Abstract
Description
Technical Field
[0001] This application relates to the field of target drone fuel tanks, and more particularly to an integrated fuel supply system for target drones. Background Technology
[0002] Target drones are military unmanned aerial vehicles used as shooting training targets. In order to simulate a more realistic combat environment, target drones need to have good maneuverability and perform complex flight maneuvers, thereby providing pilots with a better training environment.
[0003] The target drone uses a fuel engine as its power source. The fuel engine provides ample power and stable performance, enabling the target drone to move at high speeds. Even when the target drone is flying at high altitudes, the fuel engine can still provide good power. The target drone is equipped with a fuel tank to hold fuel and supply fuel to the fuel engine.
[0004] The aforementioned technical solutions have the following drawbacks: during the flight of the target drone, the fuel in the fuel tank gradually decreases, and the direction of the acceleration experienced by the target drone during flight is uncertain, which makes the position of the fuel in the fuel tank uncertain, resulting in different positions of the overall center of gravity of the fuel tank and poor stability of the target drone during flight. Utility Model Content
[0005] In order to keep the center of gravity stable during the fuel tank supply process, this application provides an integrated fuel supply system for a target drone.
[0006] The target drone integrated oil supply system provided in this application adopts the following technical solution:
[0007] An integrated oil supply system for a target drone includes a housing, multiple partitions, an upper partition, and a lower partition. The multiple partitions are fixed inside the housing and divide the housing into multiple oil tanks. The upper partition and the lower partition are arranged between two adjacent partitions. Multiple sealing joints and oil pipes are provided inside the housing. The sealing joints are used for installation inside the housing. Both ends of the oil pipes are connected to the sealing joints respectively. The oil pipes connect two non-adjacent oil tanks inside the housing.
[0008] By adopting the above technical solution, multiple partitions are set in the housing, and upper and lower partitions are set between two partitions, thus dividing the housing into multiple fuel tanks. When the housing supplies fuel to the engine, the engine draws fuel from the fuel tank in the middle of the housing through fuel pipes, connecting non-adjacent fuel tanks. This creates a swirling flow field of fuel within the housing. As the fuel flows, it flows sequentially through multiple fuel tanks along a fixed trajectory until it enters the engine. This ensures that the center of gravity of the housing is at the center of the housing whether it is fully loaded or unloaded. When the user fixes the housing in the target drone, by aligning the center of gravity of the housing with the center line of the target drone, the target drone can maintain good balance whether it is fully loaded or unloaded.
[0009] Optionally, the housing includes a side cylinder, an oil inlet end plate, and an oil outlet end plate. The side cylinder is a cylindrical structure. The oil inlet end plate and the oil outlet end plate are respectively sealed and fixed at both ends of the side cylinder. The oil outlet end plate has oil inlet and outlet holes. The housing is connected to the engine and supplies oil through the oil inlet and outlet holes. The partition includes an oil inlet side partition, an oil outlet side partition, and a middle partition. The oil inlet side partition is installed in the housing near the oil inlet end plate. The oil outlet side partition is located in the housing near the oil outlet end plate. The middle partition is located between the oil inlet side partition and the oil outlet side partition. The upper partition is horizontally fixed between the middle partition and the oil outlet side partition. The lower partition is fixed between the middle partition and the oil outlet side partition and located on one side of the upper partition. The oil outlet end plate is connected to the oil outlet side partition through an oil pipe. The upper partition has a through hole.
[0010] By adopting the above technical solution, a housing is formed by using a side cylinder, an inlet end plate, and an outlet end plate. An inlet side partition, an outlet side partition, and a central partition are sequentially arranged along the length of the housing. This allows the engine to draw oil from the inlet and outlet holes of the outlet end plate. These holes are connected to the fuel supply tank via oil pipes. The fuel supply tank is connected to a secondary fuel tank, which in turn is connected to a side fuel tank and an auxiliary fuel tank. The side fuel tank is connected to a primary fuel tank. When the fully loaded housing supplies fuel to the engine, the fuel in the fuel supply tank decreases, and the secondary fuel tank supplies fuel to the fuel supply tank. The fuel in the secondary fuel tank comes from the side fuel tank and the auxiliary fuel tank, while fuel from the primary fuel tank flows into the side fuel tank. During the fuel supply process, the fuel flow path is close to the center of gravity of the housing, thus minimizing the shift in the center of gravity of the housing during fuel consumption.
[0011] Optionally, the sealing joint is provided with a threaded cylinder at one end and an oil pipe cylinder at the other end. The threaded cylinder is used to connect to the threaded hole on the housing and the partition, and the oil pipe cylinder is used to seal the connection with the end of the oil pipe.
[0012] By adopting the above technical solution, and by setting a threaded cylinder on the sealing joint, the sealing joint can be threaded onto the end face of the housing and the partition frame, thereby facilitating the connection of oil pipes to different positions inside the housing and making installation convenient.
[0013] Optionally, the oil inlet side partition is provided with a threaded through hole, and the middle partition is provided with a threaded through hole. The oil inlet side partition and the middle partition are connected by an oil pipe.
[0014] By adopting the above technical solution, by opening threaded through holes on the oil inlet side partition, the oil inlet side partition and the middle partition are connected by oil pipes, thereby connecting the first section oil tank and the side oil tank. When the fuel in the first section oil tank is consumed, the second section oil tank retains more fuel, thus reducing the weight of the first section oil tank side in the tank body and reducing the shift of the center of gravity of the tank body.
[0015] Optionally, the oil outlet side partition is connected to the middle partition.
[0016] By adopting the above technical solution, the oil outlet side partition is connected to the middle partition. When the engine draws oil from the housing, the engine draws fuel from the fuel supply tank. The fuel supply tank is located on the lower side of the middle of the housing, so that the fuel supply tank always has a lot of fuel. When the fuel in the fuel supply tank is consumed, the fuel in other tanks automatically flows into the fuel supply tank under the action of gravity.
[0017] Optionally, an integrated tube is provided on the upper partition, and holes are formed on the side wall of the upper partition to form a channel for the integrated tube.
[0018] By adopting the above technical solution, by opening an integrated pipe on the upper partition plate to connect the oil supply tank and the second-stage oil tank, and by opening a hole on the side wall of the upper partition plate to form a channel for the integrated pipe, the steps of setting up oil pipes in the tank are reduced, thus saving space in the tank.
[0019] Optionally, one end of the integrated pipe is located between the lower partition and the oil outlet side partition and has an inclined surface. The end of the integrated pipe is opened as an inclined oil outlet. The top of the inclined oil outlet is a flat arc, and the rest is an inclined surface. The flat arc occupies 20% of the overall pipeline circumference, and the angle between the inclined surface and the pipeline central axis is 70°.
[0020] By adopting the above technical solution, by opening a bevel at the end of the integrated pipe, the area at the end of the integrated pipe is made larger, which reduces the probability of solid impurities in the fuel clogging the integrated pipe and keeps the integrated pipe unobstructed.
[0021] Optionally, an integrated pipe II is provided on the upper partition plate. The integrated pipe II is formed by opening a hole in the side wall of the upper partition plate and is used to connect the oil outlet side partition frame and the middle partition frame.
[0022] By adopting the above technical solution, by opening an integrated pipe 2 on the upper partition, the two-stage oil tank and the auxiliary oil tank can be connected through the through hole in the upper partition, thereby reducing the steps of installing multiple sealing joints and oil pipes in the tank, saving space in the tank and increasing the tank volume.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By setting multiple partitions in the housing and setting upper and lower partitions between two partitions, multiple fuel tanks are divided inside the housing. When the housing supplies fuel to the engine, the engine draws fuel from the fuel tank in the middle of the housing through the fuel pipe, so that the fuel pipe connects the non-adjacent fuel tanks, thereby forming a swirling flow field of fuel in the housing. When the fuel flows, the fuel flows sequentially in multiple fuel tanks along a fixed trajectory until it enters the engine. This ensures that the center of gravity of the housing is at the center of the housing when it is fully loaded or unloaded. When the user fixes the housing in the target drone, by aligning the center of gravity of the housing with the center line of the target drone, the target drone can maintain better balance when it is fully loaded or unloaded.
[0025] 2. By using a side cylinder, an inlet end plate, and an outlet end plate to form a housing, an inlet side partition, an outlet side partition, and a middle partition are sequentially arranged along the length of the housing. The engine draws oil from the inlet and outlet holes of the outlet end plate. The inlet and outlet holes are connected to the fuel supply tank through oil pipes. The fuel supply tank is connected to the second-stage fuel tank. The second-stage fuel tank is connected to the side fuel tank and the auxiliary fuel tank respectively. The side fuel tank is connected to the first-stage fuel tank. When the housing is fully loaded with fuel and supplies fuel to the engine, the fuel in the fuel supply tank decreases. The second-stage fuel tank supplies fuel to the fuel supply tank. The fuel in the second-stage fuel tank comes from the side fuel tank and the auxiliary fuel tank. The fuel in the first-stage fuel tank flows into the side fuel tank. During the fuel supply process, the flow path of the fuel is close to the center of gravity of the housing, so that the degree of shift of the center of gravity of the housing is small during the fuel consumption process.
[0026] 3. By opening an integrated pipe on the upper partition, the integrated pipe connects the oil supply tank and the second-stage oil tank. The opening on the side wall of the upper partition forms the channel for the integrated pipe, thereby reducing the steps of installing oil pipes inside the tank and saving space inside the tank.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.
[0035] This application discloses an integrated oil supply system for a target drone, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a housing 1, multiple partitions 2, an upper partition 4, and a lower partition 5. The housing 1 has an oil inlet / outlet port 14 and is used to store fuel. The multiple partitions 2 are located inside the housing 1, dividing the housing 1 into multiple fuel tanks. The upper partition 4 and the lower partition 5 are located between the partitions 2, further separating the fuel tanks. The housing 1 is equipped with a sealing joint 6 and an oil pipe 7. The sealing joint 6 is used to connect the two sides of the partitions 2, and the oil pipe 7 is located in the housing 1 and connects to fuel tanks at different locations. When the housing 1 supplies fuel to the engine, the oil pipe on the engine is connected to the fuel tank located in the middle of the housing 1, thereby drawing fuel from the middle of the housing 1. During the process of the engine consuming fuel, the fuel in the housing 1 is consumed evenly, so that the center of gravity of the housing 1 remains relatively stable during the fuel consumption process. The overall weight distribution of the target drone is even during flight, so that the flight state of the target drone is relatively stable when it is full of fuel and when it consumes a lot of fuel.
[0036] Reference Figure 1 , Figure 2 and Figure 3 The housing 1 includes a side cylinder 11, an inlet end plate 12, and an outlet end plate 13. The side cylinder 11 has a cylindrical structure. The inlet end plate 12 and the outlet end plate 13 are respectively fixed to both ends of the side cylinder 11. The side cylinder 11, the inlet end plate 12, and the outlet end plate 13 together form a cylindrical structure to store fuel. Both the inlet end plate 12 and the outlet end plate 13 are provided with inlet and outlet holes 14. Fuel can flow into the housing 1 from the inlet and outlet holes 14 on the inlet end plate 12. The inlet and outlet holes 14 on the outlet end plate 13 are connected to the engine through an oil pipe 7.
[0037] Reference Figure 1 , Figure 2 and Figure 3The partition 2 includes an oil inlet side partition 21, an oil outlet side partition 22, and a middle partition 23, all of which are circular plate structures. The oil inlet side partition 21 is fixed inside the housing 1 on the side near the oil inlet end plate 12, the oil outlet side partition 22 is located inside the housing 1 on the side near the oil outlet end plate 13, and the middle partition 23 is located between the oil inlet side partition 21 and the oil outlet side partition 22. The space between the oil inlet end plate 12 and the oil inlet side partition 21 forms a first-section oil tank 81, the space between the oil inlet side partition 21 and the middle partition 23 forms a second-section oil tank 82, the space between the middle partition 23 and the oil outlet side partition 22 forms a third-section oil tank 83, and the space between the oil outlet side partition 22 and the oil outlet end plate 13 forms a secondary oil tank 84. When the engine starts, it draws fuel from the three fuel tanks 83, which makes the overall weight of the tank 1 drop evenly and minimizes the change and shift of the overall center of gravity of the tank 1.
[0038] Reference Figure 2 , Figure 3 and Figure 4 An upper partition 4 and a lower partition 5 are provided between the middle partition 23 and the oil outlet side partition 22. The upper partition 4 is arranged parallel to the axis of the tank 1. The two ends of the upper partition 4 are sealed to the oil outlet side partition 22 and the middle partition 23 respectively. The two ends of the upper partition 4 in the width direction are sealed to the side cylinder 11. The upper partition 4 divides the three oil tanks 83 into an upper oil tank 86 and a lower oil tank. The lower partition 5 is perpendicular to the upper partition 4 and is fixed between the oil outlet side partition 22 and the middle partition 23. The lower partition 5 divides the lower fuel tank into a side fuel tank 85 and a fuel supply tank 87. The fuel supply tank 87 is formed by the lower partition 5, the upper partition 4, the fuel outlet side partition 22, and the side cylinder 11. The fuel outlet side partition 22 has a threaded hole, and the sealing joint 6 is threaded into the threaded hole of the fuel outlet side partition 22. The sealing joint 6 is connected to the oil pipe 7, and the oil pipe 7 connects the fuel outlet side partition 22 and the oil inlet and outlet holes 14 on the fuel outlet end plate 13, so that the engine outside the housing 1 can draw fuel from the fuel supply tank 87 through the oil inlet and outlet holes 14 on the fuel outlet end plate 13.
[0039] Reference Figure 1 , Figure 2 and Figure 3The fuel supply tank 87 is connected to the second-stage fuel tank 82, and the second-stage fuel tank 82 is connected to the first-stage fuel tank 81. When the fuel in the fuel supply tank 87 decreases, the second-stage fuel tank 82 and the first-stage fuel tank 81 supply fuel to the fuel supply tank 87. A through hole 41 is provided on the upper partition 4, through which the upper fuel tank 86 and the side fuel tank 85 are connected. A through hole is provided on the middle partition frame 23, through which the second-stage fuel tank 82 and the side fuel tank 85 are connected, and the auxiliary fuel tank 84 is connected to the second-stage fuel tank 82. When the tank body 1 is full of fuel, when the engine starts, fuel is drawn from the fuel supply tank 87. The fuel flows through the pipe below the first-stage fuel tank 81 into the side fuel tank 85, and then through the side fuel tank 85 into the second-stage fuel tank 82. The fuel in the second-stage fuel tank 82 flows into the fuel supply tank 87. The auxiliary fuel tank 84 is connected to the second-stage fuel tank 82. The central bulkhead 23 has the greatest weight, while the second-section fuel tank 82 and the third-section fuel tank 83 have a large volume. This results in the overall center of gravity of the container 1 being located near the central bulkhead 23. When the fuel in the container 1 decreases, the fuel in each fuel tank section of the container 1 decreases evenly, and the weight distribution is concentrated near the central bulkhead 23. As a result, when the container 1 is installed inside the target drone, the center of gravity of the container 1 and the center of gravity of the target drone are located on the same vertical line, and the overall weight distribution of the target drone is even, so that the left and right wings remain balanced during flight.
[0040] Reference Figure 5 and Figure 6 The upper partition 4 is equipped with integrated pipe 1 42 and integrated pipe 2 43. Integrated pipe 1 42 connects the second-stage oil tank 82 and the supply oil tank 87, and integrated pipe 2 43 connects the second-stage oil tank 82 and the auxiliary oil tank 84. Integrated pipe 1 42 and integrated pipe 2 43 are formed by opening holes in the side wall of the upper partition 4. By opening holes in the upper partition 4, holes are formed in the side wall of the upper partition 4. When the upper partition 4 is installed on the oil outlet side partition 22 and the middle partition 23, the holes in the side wall of the upper partition 4 correspond to the positions of the through holes on the oil outlet side partition 22 and the middle partition 23, respectively, thereby achieving the effect of connecting different oil tanks, reducing the steps of setting oil pipes in the oil tank, and increasing the oil storage space in the oil tank.
[0041] Reference Figure 5 and Figure 6 One end of the integrated pipe 42 is located in the middle of the upper partition plate 4, so that the integrated pipe 42 is positioned above the oil supply tank 87. The end of the integrated pipe 42 is provided with a bevel 421, so that the end of the integrated pipe 42 is opened as a beveled oil outlet. The top of the beveled oil outlet is a flat arc, and the rest is a bevel. The flat arc occupies about 20% of the overall circumference of the pipeline, and the angle between the bevel and the central axis of the pipeline is about 70°. By providing a bevel 421 at the end of the integrated pipe 42, the oil outlet area can be increased and the probability of oil outlet blockage can be reduced.
[0042] Reference Figure 4The sealing joint 6 has a cylindrical structure. One end of the sealing joint 6 is provided with a threaded cylinder 61, and the other end is provided with an oil pipe cylinder 62. The outer wall of the threaded cylinder 61 is threaded, which can be threaded into threaded holes at different positions inside the housing 1. The oil pipe cylinder 62 is used for sealing connection with the oil pipe 7. By providing multiple sealing joints 6 inside the housing 1, sealing joints 6 can be installed at both ends of the oil pipe 7, thereby allowing the sealing joints 6 and the oil pipe 7 to connect to non-adjacent oil tanks.
[0043] Reference Figure 3 A sealing joint 6 is installed on the central partition 23. The sealing joint 6 is connected to the end of the integrated pipe 42. An oil pipe 7 is connected to the sealing joint 6. The oil pipe 7 is located inside the second-stage fuel tank 82. When the fuel supply tank 87 supplies fuel to the engine, the fuel supply tank 87 draws fuel from the second-stage fuel tank 82 through the integrated pipe 42 and the oil pipe 7. The end of the oil pipe 7 is located near the center line of the housing 1, so that when the target drone flies at different angles, the fuel in the second-stage fuel tank 82 can stably enter the fuel supply tank 87 through the oil pipe 7, thus ensuring stable power for the target drone when performing high-difficulty maneuvers. The end of the oil pipe 7 has a bevel 71. The top of the beveled oil outlet is a flat arc, and the rest is a bevel. The flat arc occupies about 20% of the overall circumference of the pipeline, and the angle between the bevel and the central axis of the pipeline is about 70°, reducing the chance of oil outlet blockage.
[0044] The implementation principle of this application embodiment is as follows: by setting multiple partitions 2 inside the housing 1, and setting an upper partition 4 and a lower partition 5 between the oil outlet side partition 22 and the middle partition 23, the housing 1 is divided into multiple oil tanks. By setting multiple sealing joints 6 and oil pipes 7 inside the housing 1, the oil pipes 7 can connect non-adjacent oil tanks. When the housing 1 supplies fuel to the engine, the flow field of the fuel flowing inside the housing 1 is close to the center of the housing 1, so that the center of gravity of the housing 1 remains stable during the fuel consumption process, thereby enabling the target drone to maintain better balance during flight.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
