Description

Technical Field

[0001] The invention belongs to the field of projectile testing and experiment, relates to the lossless recovery of projectiles, and specifically is a high-speed projectile lossless recovery device. Background Art

[0002] In most cases, it is desirable to recover the test projectile after launch in order to determine the projectile's ballistic characteristics. For example, the range extension device, terminal guidance device, and trajectory correction device in modern information-based ammunition are primarily composed of precision components. During the development process, simulation experiments involving the high-overload resistance performance of these components and the ballistic linkage characteristics of related components are required. These experiments require the test projectile to be able to be recovered non-destructively after launch to determine the usability of these components, the correctness of the ballistic linkage characteristics, or the feasibility of the high-overload resistance measures. In the testing and research of new ammunition penetrators, non-destructive recovery of the test projectile is also required to observe the projectile's state after penetration and determine the projectile's penetration effect.

[0003] Currently, commonly used recycling methods include water damping recycling, gas damping recycling, sandbox recycling, flour recycling, foam aluminum recycling, and segmented recycling devices. The disadvantages of these recycling methods are that they are large in size, require a large amount of space, and cannot be reused, resulting in a waste of resources.

[0004] Therefore, it is necessary to design a small, reusable projectile non-destructive recovery device. Summary of the Invention

[0005] The purpose of the present invention is to provide a device which is low in cost and can realize lossless recovery of projectiles with different calibers and different speeds.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-speed projectile non-destructive recovery device includes: a bracket, a buffer plate, a slide rail, a bullet collecting plate assembly, a one-way plate, a linear isolator and a buffer spring; the bracket is fixedly provided with a slide rail, the buffer plate and the one-way plate are slidably installed on the slide rail and move linearly along the slide rail, and the buffer plate is connected to the bullet collecting plate assembly through a connecting piece; a buffer spring and a washer are provided at the end of the slide rail along the shooting direction of the projectile, and the buffer spring is used to absorb the energy of the buffer plate and the one-way plate, thereby reducing the speed; a linear isolator is provided at the rear end of the bracket to limit the reverse movement of the one-way plate.

[0007] Furthermore, the bullet receiving plate assembly includes a bullet receiving plate and a silicone rubber member, and the silicone rubber member is fixedly mounted on the surface of the bullet receiving plate facing the buffer plate.

[0008] Furthermore, the bracket, the buffer plate and the one-way plate are all provided with through holes, and the centers of the three through holes are in the same straight line with the trajectory of the projectile movement.

[0010] Furthermore, a retaining rod is fixedly provided on the buffer plate to support the entire bullet collecting plate assembly at the rear.

[0011] Furthermore, the one-way rod is fixed to the one-way plate through a threaded connection.

[0012] Furthermore, the elastic plate is made of aramid fiber composite material, and the connecting piece is made of elastic material.

[0013] Furthermore, the projectile non-destructive recovery device includes five levels of buffering:

[0014] When the projectile penetrates the silicone rubber, part of the projectile's kinetic energy is transferred to the silicone rubber, which is defined as the first-level buffer;

[0015] The receiving plate assembly, which is made of silicone rubber and a receiving plate, tightens the connector, and part of the kinetic energy of the projectile is transferred to the elastic material, which is defined as the secondary buffer;

[0027] To help those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] like Figure 1-5 As shown, the present invention provides a high-speed projectile lossless recovery device, comprising: a bracket 7, a slide rail 14, a buffer plate 1, a buffer spring 5, a bullet receiving plate assembly, a one-way plate 3 and a linear one-way device 4.

[0029] Among them: the entire projectile recovery device bracket 7 is fixedly provided with a slide rail 14, the buffer plate 1 and the one-way plate 3 are slidably installed on the slide rail 14 and move linearly along the slide rail 14, the buffer plate 1 is connected to the bullet collecting plate assembly through a connector 10, and a buffer spring 5 and a washer 6 are provided at the end of the slide rail 14 along the projectile shooting direction, which are used to absorb the energy of the buffer plate 1 and the one-way plate 3, thereby reducing the speed;

[0030] A linear isolator 4 is installed at the rear end of bracket 7. A one-way rod 12 is installed on one-way plate 3. This rod 12 passes through the center of linear isolator 4. After one-way plate 3 is impacted and compresses spring 5 in the direction of projectile movement, it will not move in the opposite direction due to the spring 5's rebound force.

[0031] Among them, the bracket 7, the buffer plate 1, and the one-way plate 3 are provided with through holes, and the centers of the through holes are in the same straight line with the trajectory of the projectile;

[0032] The bullet receiving plate assembly includes a bullet receiving plate 2 and a silicone rubber member 9 . The silicone rubber member 9 is adhered to the surface of the bullet receiving plate 2 facing the buffer plate 1 by strong glue.

[0033] The buffer plate 1 and the bullet receiving plate 2 are respectively provided with eye screws 13. The connecting piece 10 passes through the eye screws 13 on the buffer plate 1 and the bullet receiving plate 2, thereby connecting the buffer plate 1 and the bullet receiving plate 2 together.

[0034] A retaining rod 8 is fixedly provided on the buffer plate 1, and the entire bullet receiving plate 2 at the rear is supported by the retaining rod 8.

[0035] Among them, the one-way rod 12 is fixed on the one-way plate 3 through a threaded connection;

[0036] The elastic plate 2 is made of aramid fiber composite material, and the connecting piece 10 is made of elastic material;

[0037] When a projectile is fired from the ballistic gun, it first contacts and penetrates silicone rubber element 9 at high speed. Once penetration reaches a certain level, it tightens connector 10 under the restraint of bullet receiving plate 2. This in turn drives buffer plate 1 along slide rail 14. After moving a certain distance, buffer plate 1 collides with one-way plate 3, driving both along the projectile's direction of motion. This gradually compresses buffer spring 5, and the speeds of both buffer plate 1 and one-way plate 3 gradually decrease to zero. Furthermore, due to the action of linear one-way spring 4, one-way plate 3 does not rebound after the spring 5 is compressed to its limit.

[0038] At the same time, when the projectile penetrates the silicone rubber 9, a portion of the projectile's kinetic energy is transferred to the silicone rubber 9, defining this as primary buffering. The silicone rubber 9 and the bullet collecting plate 2 are bonded together to form a tensioning connector 10, transferring a portion of the projectile's kinetic energy to the elastic material 10, defining this as secondary buffering. This drives the buffer plate 1 into motion, transferring a portion of the projectile's kinetic energy to the buffer plate 1, defining this as tertiary buffering. The buffer plate 1 strikes the one-way plate 3, transferring a portion of the projectile's kinetic energy to the one-way plate 3 during the collision, defining this as fourth-level buffering. During the compression of the buffer spring 5, a portion of the projectile's kinetic energy is transferred to the spring, causing compression, defining this as fifth-level buffering. Through these multiple levels of buffering, the projectile's kinetic energy is gradually reduced, achieving lossless recovery of high-speed projectiles.

[0039] The high-speed projectile lossless recovery device of the present invention has the following characteristics:

[0040] 1. The projectile recovery device has a simple structure and is easy to assemble.

[0041] 2. The projectile impact area is small, causing less damage to the projectile.

[0042] 3. The bullet collecting plate assembly is small in size, making it easy to find the bullets after recovery.

[0043] 4. The bullet recovery plate assembly is easy to replace, which can realize the projectile recovery test under various conditions.

[0044] In summary, compared with previous recovery methods, the high-speed projectile non-destructive recovery device of the present invention has a simple structure, smaller size, and less damage to the projectile. It can achieve non-destructive recovery of projectiles of different calibers and different speeds. During the test, it only needs to replace the appropriate bullet collecting plate assembly to achieve reuse, reducing resource waste.

[0045] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is clear to those skilled in the art that various equivalent variations or substitutions may be made without violating the spirit of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
