Description

Technical Field

[0001] The utility model relates to the technical field of projectile launching, in particular to a sealing ring for a tail-stabilized armor-piercing projectile. Background Art

[0002] With the continuous improvement of aircraft performance and the increasing sophistication and development of missile technology, low- and ultra-low-altitude penetration techniques are rapidly advancing. Objects at sea and on the ground are subject to multi-layered, multi-target attacks from all directions at any time. Fin-stabilized armor-piercing projectiles are one of the primary means of engaging armored targets on the modern battlefield. However, my country's armor-piercing projectiles have been slow to develop and still lag behind the world's advanced levels, particularly in terms of their launch intensity and power design. Their structure primarily consists of a multi-part sabot, a flight body, a belt, and other gas-tightening features. The tight integration of these three components, which isolates the propellant gases, is one of the key factors in achieving high muzzle velocities. Therefore, the sealing ring plays a crucial role. Given the saddle-shaped sabot, a suitable and effective gas-tightening feature can significantly increase the projectile's muzzle velocity and penetration energy, enhancing its power and launch intensity. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and to provide a sealing ring for a fin-stabilized armor-piercing projectile, thereby reducing the weight and ensuring good sealing performance.

[0004] The purpose of the utility model is achieved by the following technical solutions: a sealing ring for a fin-stabilized armor-piercing projectile, comprising a sealing ring for being placed on a fin-stabilized armor-piercing projectile, the sealing ring comprising an upper circular ring, an oblique circular ring, a lower circular ring and rectangular teeth, the rectangular teeth comprising a first rectangular tooth, a second rectangular tooth and a third rectangular tooth;

[0005] The outer diameter of the upper ring is 16mm, the inner diameter is 10.5mm, and the overall thickness of the upper ring is 1.75mm. The outer diameter of the beveled ring is 16mm, the internal bevel angle is 135°, and the overall thickness of the beveled ring is 1.25mm. The outer diameter of the lower ring is 16mm, and the inner diameter is 13mm. The overall thickness of the lower ring is 1mm. The length and width of the first rectangular tooth, the second rectangular tooth and the third rectangular tooth are all 3mm.

[0006] In the sealing ring for the fin-stabilized armor-piercing projectile of the present invention, the first rectangular teeth, the second rectangular teeth and the third rectangular teeth are all arranged on the outside.

[0007] In the sealing ring for the fin-stabilized armor-piercing projectile of the present invention, the sealing ring is made of plastic material.

[0008] The utility model has the following advantages:

[0009] 1. The utility model is used for a sealing ring placed on a fin-stabilized armor-piercing projectile. The sealing ring includes an upper circular ring, an oblique circular ring, a lower circular ring, and rectangular teeth. The upper circular ring, the oblique circular ring, the lower circular ring, and the rectangular teeth are integrally formed. The rectangular teeth include a first rectangular tooth, a second rectangular tooth, and a third rectangular tooth. The first rectangular tooth, the second rectangular tooth, and the third rectangular tooth are arranged at equal intervals on a plane.

[0010] The outer diameter of the upper ring is 16mm, the inner diameter is 10.5mm, and the overall thickness of the upper ring is 1.75mm. The outer diameter of the beveled ring is 16mm, the internal bevel angle is 135°, and the overall thickness of the beveled ring is 1.25mm. The outer diameter of the lower ring is 16mm, and the inner diameter is 13mm. The overall thickness of the lower ring is 1mm. The length and width of the first rectangular tooth, the second rectangular tooth and the third rectangular tooth are all 3mm, which reduces the weight while ensuring the sealing is intact. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural diagram of the utility model;

[0012] Figure 2 It is a schematic diagram of the planar structure of the present utility model.

[0013] In the figure, there are a sealing ring 1, an upper circular ring 2, an oblique circular ring 3, a lower circular ring 4, rectangular teeth 5, a first rectangular tooth 6, a second rectangular tooth 7, and a third rectangular tooth 8. DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings. The scope of protection of the present invention is not limited to the following:

[0015] like Figure 1~Figure 2 As shown, a sealing ring for a fin-stabilized armor-piercing projectile includes a sealing ring 1 for placement on a fin-stabilized armor-piercing projectile, the sealing ring 1 including an upper circular ring 2, an oblique circular ring 3, a lower circular ring 4, and rectangular teeth 5, wherein the rectangular teeth 5 are provided with a first rectangular tooth 6, a second rectangular tooth 7, and a third rectangular tooth 8;

[0016] In this embodiment, the outer diameter of the upper ring 2 is 16 mm, the inner diameter is 10.5 mm, the overall thickness of the upper ring 2 is 1.75 mm, the outer diameter of the beveled ring 3 is 16 mm, the internal bevel angle is 135°, the overall thickness of the beveled ring 3 is 1.25 mm, the outer diameter of the lower ring 4 is 16 mm, and the inner diameter is 13 mm, the overall thickness of the lower ring 4 is 1 mm, and the length and width of the first rectangular tooth 6, the second rectangular tooth 7 and the third rectangular tooth 8 are all 3 mm.

[0017] In this embodiment, the first rectangular teeth 6 , the second rectangular teeth 7 and the third rectangular teeth 8 are all arranged on the outside.

[0018] In this embodiment, the sealing ring 1 is made of plastic material.

[0019] The working principle of this utility model is as follows: the complex sabot structure of tungsten alloy armor-piercing projectiles creates a complex structure between the core and the sabot. A simple sealing ring structure cannot achieve this function. Therefore, a new external structure is designed to meet this requirement. The sabot is formed by three clips, and a slot for the sealing ring is left during processing. The overall sealing ring structure consists of a circular ring and three rectangular shapes evenly distributed around it. Because the core has a serrated groove to transfer the force between the core and the sabot, the inner part of the circular ring has a serrated chamfer. To ensure good sealing and low weight, the material is plastic.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
