Description

Technical Field

[0001] This utility model relates to the technical field of training ammunition accessories, specifically to a wind cap structure for training ammunition. Background Technology

[0002] In ammunition design, the flight performance of a projectile is affected by a variety of factors, among which air resistance is one of the key factors. During flight, the projectile is subject to air resistance, which directly affects the projectile's range, accuracy, and overall flight stability. Generally, in order to reduce wind resistance during projectile flight, designers often design a wind cap structure at the projectile's nose to reduce air resistance during the projectile's flight.

[0003] However, training rounds are usually equipped with tracer devices at the tail. The tracer can produce a certain drag reduction effect during combustion, which makes the drag coefficient of the training rounds different from that of the standard rounds, resulting in poor training effect. Utility Model Content

[0004] To solve the above problems, this utility model provides a wind cap structure for training ammunition, which is achieved through the following technical solution.

[0005] A wind cap structure for training projectiles includes an integrally formed face column and a connecting column. The face column is frustum-shaped, and the connecting column is located at the center of the large circular surface of the face column. The connecting column has an integrally formed threaded groove for connecting with the projectile of the training projectile.

[0006] As a further embodiment of this invention, the diameter of the connecting column is smaller than the diameter of the large circular surface of the wind-facing column, so that a step is formed at the connection between the connecting column and the wind-facing column.

[0007] As a further embodiment of this utility model, a wrench hole is provided on the outer wall of the wind-facing column near the connecting column.

[0008] As a further embodiment of this invention, the bottom of the hood is provided with a weight-reducing hole.

[0009] The beneficial effects of this invention are that the wind cap structure for training rounds effectively counteracts the drag reduction effect of the trailing device at the tail of the training round, making the drag coefficient of the training round closer to that of the standard round, thus improving the training effect. Furthermore, the bottom weight reduction hole achieves a balance between lightweight and strength, and the wrench hole and small step design facilitate assembly and maintenance. Overall, it significantly improves the simulated combat performance and ease of operation of the training round. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-2 As shown, a wind cap structure for training projectiles includes an integrally formed face wind column 1 and a connecting column 2. The face wind column 1 is frustum-shaped, and the connecting column 2 is located at the center of the large circular surface of the face wind column 1. The connecting column 2 has an integrally formed threaded groove 3 for connecting with the projectile of the training projectile.

[0015] The top diameter of the face wind column 1 is Φ7.5mm and the cone angle is 19°. The wind cap is installed on the training projectile through the threaded groove 3. When the projectile is launched, the face wind column 1 can increase the wind resistance, so that the drag coefficient of the training projectile is similar to that of the standard projectile.

[0016] Preferably, the diameter of the connecting column 2 is smaller than the diameter of the large circular surface of the wind-facing column 1, so that a step is formed at the connection between the connecting column 2 and the wind-facing column 1.

[0017] The steps formed are used for positioning, making it easier for the hood to be smoothly placed into the container by a robotic arm.

[0018] Preferably, a wrench hole 4 is provided on the outer wall of the wind column 1 near the connecting column 2.

[0019] The diameter of the wrench hole 4 is Φ3mm, and the maximum hole depth is 3mm. The wrench can be used to screw the air cap in or out of the bullet.

[0020] Preferably, the bottom of the hood has a weight-reducing hole 5.

[0021] The weight reduction hole 5 has a diameter of Φ10mm and a depth of 25mm to ensure that the wind cap meets the weight distribution requirements.

[0022] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
