Description

Technical Field

[0001] The invention relates to a water surface target for aerial delivery, belonging to the technical field of water targets. Background Art

[0002] Water targets are special devices used for military tests and training. They are mainly used to simulate the target characteristics of surface ships (such as radar scattering, infrared radiation, etc.) to provide a realistic combat environment for anti-ship weapon testing and troop training. The layout of water targets is generally carried out by air drop. After the water targets are carried by transport aircraft or other flying equipment and fly to the designated location (lake or sea surface), the operators drop the targets from the air.

[0003] Water targets usually include a float and a target surface. The float provides buoyancy to ensure that the target floats stably in the water. The target surface serves as a visual target for shooting or identification. There are many types of floats, such as air floats and foam-filled floats. Among them, inflatable floats are the most commonly used type of floats.

[0004] Usually, when dropping targets made of inflatable floats from the air, the floats must first be inflated on the flight equipment to ensure that they can float normally on the water surface, and then the operators will drop them. However, since the targets are easily affected by complex environments such as wind and airflow when falling from high altitudes, the following problems are likely to occur during the drop: 1. The targets are easily damaged when dropped onto the water surface; 2. The landing point of the targets is likely to deviate from the designated location. Summary of the invention

[0005] The purpose of the present invention is to provide a water surface target for aerial delivery, which can avoid damage to the target during the delivery process and improve the accuracy of the target landing point. At the same time, the entire delivery process is quick to operate, and the delivery operation is efficient and safe.

[0006] The present invention is achieved through the following technical solutions.

[0007] A surface target for aerial delivery, comprising: Target body; A protective shell having a closed protective space for accommodating the target body, the protective shell being composed of at least two separable shell blocks; at least one restraining component having a first state for keeping the plurality of shell blocks in a spliced ​​combination and a second state for releasing the spliced ​​combination, when in the first state, the plurality of spliced ​​shell blocks fix the target body in the protective shell; when in the second state, the plurality of shell blocks can be separated so that the target body can be separated from the protective shell; The target body is configured with an inflatable expansion structure and an inflatable structure for inflating the inflatable expansion structure. The inflatable expansion structure has a contracted state when not inflated and an expanded state capable of floating on the water surface after being inflated. When the protective shell is dropped to a designated position, the inflatable expansion structure is inflated to generate a radial expansion force to drive the restraining component to switch from a first state to a second state.

[0008] As a further improvement of the present invention, when the restraining component is in the first state, it embraces the outside of the protective shell to apply a restraining force to each of the shell blocks to confine the target body within the protective shell; when the restraining component is in the second state, it releases the encircling state to release the restraining force on the multiple shell blocks, so that the target body can be detached from the protective shell.

[0009] As a further improvement of the present invention, the binding component is configured as a breakable binding member, and the breakable binding member breaks under tension when the target body is inflated to achieve switching from the first state to the second state.

[0010] As a further improvement of the present invention, the number of the restraining components is multiple, and the multiple restraining components are arranged at intervals along the axial direction of the protection shell.

[0011] As a further improvement of the present invention, the inflatable structure includes an inflatable base frame that can be horizontally suspended on the water surface after inflation and a plurality of inflatable air columns that can radially expand after inflation, and the inflatable structure connects the inflatable base frame and the inflatable air columns; the target body also includes an identification component, and the identification component is installed on the plurality of inflatable air columns.

[0012] As a further improvement of the present invention, the inflatable structure includes an inflatable container for storing inflatable gas, an inflatable tube connecting the inflatable container and the inflatable expansion structure, and an inflatable valve group for controlling the connection or closure of the inflatable tube; the inflatable base frame is connected to multiple inflatable air columns, and the connecting tube is connected to the inflatable base frame or any one of the inflatable air columns.

[0013] As a further improvement of the present invention, the inflatable container is fixed on the inflatable base frame.

[0014] As a further improvement of the present invention, it also comprises a stabilizing assembly, including a stabilizing member that can be submerged in water and a connecting member for connecting the stabilizing member and the target body.

[0015] As a further improvement of the present invention, the connecting member is connected to the inflatable base frame.

[0016] Beneficial effects of the present invention: 1. A protective shell is arranged outside the target body to form a protective layer outside the target body. When the target body falls onto the water surface at a high speed, the protective shell protects the surface of the target body, thereby reducing the impact force of the water surface on the target when the target enters the water at a high speed and reducing damage to the target.

[0017] 2. The target body is provided with an inflatable expansion structure and an inflatable structure, so that the target body can be compressed and stored in a protective shell before being dropped in the air, which significantly reduces the volume of the target body during air drop. Compared with the inflated target in the prior art, on the one hand, the overall volume of the target is reduced, which can reduce the influence of air resistance and wind force on its landing point during the falling process, and improve the accuracy of the landing point of air drop. On the other hand, it can avoid the inflation operation of the target on the flight equipment before air drop, and the target can be directly dropped from the air as a whole, which makes the entire delivery process quick and easy, and helps to improve work efficiency and safety.

[0018] 3. The embracing restraint method can ensure the integrity of the protective shell during transportation and delivery, and avoid accidental separation. At the same time, the radial expansion force generated by the inflation of the inflatable structure can directly act on the restraint component, and the state switching of the restraint component can be triggered without a complex control system, which is highly reliable.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0021] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0022] This embodiment provides a surface target for aerial delivery, referring to Figures 1 - 6 , including a target body 1, a protective shell 2 and a restraining component 3, wherein the protective shell 2 has a closed protective space for accommodating the target body 1, the protective shell 2 is composed of at least two detachable shell blocks 21, and the restraining component 3 has a first state for keeping the multiple shell blocks 21 in a spliced ​​combination state and a second state for releasing the spliced ​​combination state. When in the first state, the multiple spliced ​​and combined shell blocks 21 restrict the target body 1 in the protective shell 2, and when in the second state, the multiple shell blocks 21 can be separated so that the target body 1 can be separated from the protective shell 2.

[0023] The target body 1 is provided with an inflatable expansion structure 4 and an inflatable structure 5 for inflating the inflatable expansion structure 4 after being dropped into the air. The inflatable expansion structure 4 has a contracted state when not inflated and an expanded state capable of floating on the water surface after being inflated. When the protective shell 2 is dropped into the designated position, the inflatable expansion structure 4 is inflated to generate a radial expansion force to drive the restraining component 3 to switch from the first state to the second state.

[0024] In this embodiment, when dropped from the air, the target body 1 is compressed and stored in the protective shell 2 and dropped by the operator. The target body 1 is provided with an inflatable expansion structure 4 and an inflatable structure 5. When the inflatable expansion structure 4 is inflated, it drives the restraining component 3 to switch from the first state to the second state, and the protective shell 2 disintegrates, thereby releasing the target body 1, so that the target body 1 can be normally unfolded on the water surface.

[0025] Usually, in order to simulate the target realistically, the target is larger in size, resulting in a heavier target weight. When the target is dropped from the air onto the water surface by an airplane, the target will fall on the water surface at a relatively high speed under the action of gravity acceleration, resulting in a relatively large impact force of the water surface on the target when entering the water, which can easily cause damage to the target. In this embodiment, a protective shell 2 is arranged on the outside of the target body 1 to form a protective layer on the outside of the target body 1. When the target body 1 falls onto the water surface at a relatively high speed, the protective shell 2 contacts the water surface instead of the target body 1, thereby reducing the impact force of the water surface on the target when entering the water at a high speed, and reducing damage to the target. At the same time, it can also reduce the damage to the target body 1 caused by collision during transportation.

[0026] In the prior art, the inflated target may be affected by air resistance or wind force due to its large volume when it is dropped, causing the motion trajectory to deviate, resulting in the target deviating from the designated landing point. In this embodiment, the target body 1 is provided with an inflatable expansion structure 4 and an inflatable structure 5, so that the target body 1 can be compressed and stored in the protective shell 2 before being dropped in the air, which significantly reduces the volume of the target body 1 during the air drop. Compared with the inflated target in the prior art, on the one hand, the overall volume of the drop target is reduced, which can reduce the influence of air resistance and wind force on its landing point during the falling process, and improve the accuracy of the air drop landing point. On the other hand, it can avoid the inflation operation of the target on the flight equipment before the air drop, and directly drop the target as a whole from the air, so that the entire drop process is quick to operate, which helps to improve the work efficiency and safety.

[0027] Specifically, when the restraint assembly is in the first state, it embraces the outside of the protective shell 2, and is used to apply a radially inward restraining force to each shell block 21 to confine the target body 1 in the protective shell 2. When the restraint assembly is in the second state, it releases the embraced state to release the restraining force on multiple shell blocks 21, so that the target body 1 can be separated from the protective shell 2. The embracing restraint method ensures the integrity of the protective shell 2 during the transportation and delivery stages to avoid accidental separation. At the same time, the radial expansion force generated by the inflation of the inflatable structure 4 can directly act on the restraint component 3, and the state switching can be triggered without a complex control system, with high reliability.

[0028] In this embodiment, there are multiple restraining components 3, and the multiple restraining components 3 are arranged at intervals along the axial direction of the protective shell 2. The multiple restraining components 3 can strengthen the restricting effect on the target body 1 located in the protective shell 2, thereby preventing the target body 1 from falling out of the protective shell 2 during the falling process.

[0029] In this embodiment, the restraining component 3 can be a breakable restraining component, the material of which has a preset strength and will break after being subjected to a certain tensile force. The inflation expansion of the target body 1 applies a tensile force to the breakable restraining component. When the tensile force applied to the breakable restraining component exceeds the material strength and breaks, it switches from the first state to the second state. At this time, the shell assembly 21 loses the constraint of the restraining component 3 and automatically separates, so that the target body 1 can be separated from the protective shell 2. The use of a breakable restraining component here does not require electronic control components, and only mechanical stress can be relied on to achieve state switching, and the manufacturing cost is low. In addition, the breakable restraining component is not affected by electromagnetic interference or sea conditions, and is suitable for complex battlefield environments.

[0030] In addition, the restraining component 3 can also be selected as an elastic restraining belt, which forms a first state in a naturally contracted state and is stretched and deformed to form a second state when the target body 1 is inflated. When the elastic restraining belt is stretched and deformed, it expands outward, and multiple shell assemblies 21 are separated, so that the target body 1 can be separated from the protective shell 2.

[0031] In this embodiment, the multiple shell blocks 21 in the protective shell 2 are all made of buffer material, are semi-cylindrical and have a certain elasticity. After splicing and combination, a cylindrical closed structure is formed, which can not only limit the position of the target body 1 under the action of the restraining component 3, but also has a certain buffering effect, reducing the impact on the target body 1 when falling into water.

[0032] In this embodiment, the inflatable structure 5 includes an inflatable container 51 for storing inflatable gas, an inflatable tube 52 connecting the inflatable container 51 and the inflatable expansion structure 4, and an inflatable valve group 53 for controlling the connection or closure of the inflatable tube 52. One end of the inflatable tube 52 is connected to the gas outlet of the inflatable container 51, and the other end is connected to the inflatable expansion structure 4 so that the two are connected. The inflatable valve group 53 is arranged between one end of the inflatable tube 52 and the inflatable container 51. The inflatable container 51 here can be an industrial gas cylinder, which stores high-pressure gas. When the inflatable valve group 53 controls the inflatable tube 52 to be connected with the inflatable container 51, the high-pressure gas in the inflatable container 51 is filled into the inflatable expansion structure 4 through the inflatable tube 52, so that it is inflated and generates buoyancy, and can float on the water.

[0033] In this embodiment, the inflation valve group 53 can use an electric control valve and be equipped with a remote controller, so that the operator can remotely control the opening and closing of the electric control valve. When the operator observes that the target body 1 falls on the designated location on the water surface, the operator controls the electric control valve to open, so that the inflation container 51 can inflate the inflation structure 4, so that it changes from a contracted state to an expanded state and detaches from the protective shell 2. In addition, the inflation valve group 53 here can also use a quick release valve, that is, the operator manually releases the mechanical lock on the quick release valve, and then quickly drops the target as a whole from the flight equipment, so that the inflation container 51 can inflate the inflation structure 4, ensuring that the target body 1 can float normally on the water surface.

[0034] In this embodiment, the inflatable expansion structure 4 is made of a flexible material, which includes an inflatable chassis 41 that can be horizontally suspended on the water surface after inflation and a plurality of inflatable air columns 42 that can expand radially after inflation. The inflation structure 5 is connected to the inflatable chassis 41 and the inflatable air columns 42. The target main body 1 further includes an identification component 6, and the identification component 6 is installed on the plurality of inflatable air columns 42. The inflatable chassis 41 can be horizontally suspended on the water surface after inflation. Moreover, the inflatable chassis 41 is connected to the plurality of inflatable air columns 42, and the inflatable pipe 52 is connected to the inflatable chassis 41 or any one of the inflatable air columns 42. During inflation, it is ensured that all parts of the inflatable expansion structure 4 can expand after inflation. At the same time, the inflatable container 51 is fixed on the inflatable chassis 41 to improve the floating stability of the inflatable chassis 41 on the water surface.

[0035] It should be noted that the identification component 6 here uses a skin, which is used for the observation and locking of weapons. The skin here can be fixed to the inflatable air column 42 by stitching.

[0036] In this embodiment, a stability component 7 is further included, which includes a stabilizer 71 that can sink into the water surface and a connecting member 72 for connecting the stabilizer 71 and the target main body 1. The stabilizer 71 sinks into the water surface, and the connecting member 72 connects the target main body 1, which may help the target resist water flow or wind force, maintain a stable position, prevent drifting, and improve the positioning accuracy of the target. The stabilizer 71 here is set as an anchor, which has a certain weight to ensure that it can sink smoothly under the water surface. Moreover, the connecting member 72 is connected to the inflatable chassis 41, so that the anchoring force of the stabilizer 71 is evenly transmitted to the entire target, further enhancing the anti-overturning ability of the target main body 1 in the wind and waves. The connecting member generally uses a flexible connecting rope, so that the anchor can be bound to the outer surface of the protective shell through a binding component, avoiding the anchor hitting the target main body 1 when falling and causing damage to it.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
