Abstract
Description
Technical Field
[0001] This utility model belongs to the field of target projectile design technology, specifically relating to a device for enhancing the radiation intensity of a target projectile and a supersonic target projectile. Background Technology
[0002] With the widespread application of hypersonic weapons, supersonic aircraft, supersonic tactical ballistic missiles, and anti-radiation missiles have become key targets for air defense weapons. Against this backdrop, supersonic targets are indispensable in the development and production of anti-supersonic weapons. Targets meeting supersonic requirements mainly include target drones and target missiles. Target drones, due to their complex structure and advanced control systems, are more expensive than target missiles. For economic reasons, target missiles are generally chosen to simulate supersonic targets, and these target missiles are mainly modified from advanced missiles and rockets.
[0003] Small supersonic target missiles are mostly modified from small-caliber rockets. Their infrared radiation intensity is significantly lower than that of typical combat missiles and aircraft, necessitating the addition of flares to enhance this intensity. To prevent the influence of the flare's high temperature flame, the flare is usually mounted directly on the outside of the target missile via a bracket. However, this causes significant changes to the target missile's aerodynamic shape, severely impacting range and control stability. Furthermore, supersonic flight leads to instability in the infrared radiation characteristics of the flare's external components, hindering stable target feeding.
[0004] Therefore, it is necessary to design a device with small size and good aerodynamic shape to enhance infrared radiation intensity based on the structure of small supersonic target missiles. Utility Model Content

The tracer tube is installed inside the aerodynamic housing, and the ignition wire of the tracer tube is guided through a wire hole, minimizing its impact on the aerodynamic characteristics of the target projectile.

[0027] Reference Figure 1-2 This invention provides a device for enhancing the radiation intensity of a target projectile, comprising an aerodynamic housing, a tracer tube 4, and a base 3; the base 3 is installed at the open end of the aerodynamic housing; the tracer tube 4 is fixed inside the aerodynamic housing; the aerodynamic housing has multiple light-transmitting holes 6; a first through-hole 7 connecting the inside and outside of the aerodynamic housing is provided at the connection between the aerodynamic housing and the base 3. The aerodynamic housing, suitable for flight, provides a good aerodynamic shape for the target projectile. The tracer tube 4 can be selected as needed, preferably an infrared tracer tube 4.
[0028] During assembly, the tracer tube 4 is fixed inside the pneumatic housing. The ignition wire 9 at the front end of the tracer tube 4 passes through the first wiring hole 7 and connects to the cable inside the target projectile, thus realizing the ignition function of the tracer tube 4. The base 3 is connected to the rear end of the pneumatic housing to prevent the tracer tube 4 from detaching. The tracer tube 4 is installed inside the device, and has little impact on the aerodynamic characteristics of the target projectile during operation, and its infrared radiation characteristics are stable.
[0029] Specifically, the pneumatic outer shell includes a mounting cylinder 2 and a pneumatic head cover 1. The mounting cylinder 2 is a hollow structure with both ends open, one end connected to the pneumatic head cover 1 and the other end connected to the base 3. The pneumatic head cover 1 is preferably made of steel, which can withstand the flame erosion of the tracer tube 4, ensuring that the tracer tube 4 can work normally under the supersonic flight of the target projectile, while also reducing aerodynamic drag. The mounting cylinder 2 serves as both a mounting carrier for the tracer tube 4 and a counterweight. By changing the material and wall thickness, its own weight and center of gravity can be adjusted to ensure that the center of gravity of the device is consistent with the original target projectile's warhead.
[0030] The light-transmitting hole 6 is preferably located on the pneumatic hood 1; the propellant-loading end of the tracer tube 4 faces the pneumatic hood 1. The pneumatic hood 1 and the mounting cylinder 2 divide the internal space of the pneumatic casing into a high-temperature zone (pneumatic hood 1) and a temperature buffer zone (mounting cylinder 2). When the tracer tube 4 operates, the high-temperature flame ejected from it accumulates within the high-temperature zone and diffuses outwards through the light-transmitting hole 6 on the pneumatic hood 1, enhancing the infrared radiation intensity of the target projectile. A very small number of flames that diffuse backwards through the assembly gap accumulate within the temperature buffer zone, preventing them from diffusing into other sections of the target projectile. This serves as a heat insulation function between the device and other sections of the target projectile, preventing the high temperature of the tracer tube 4 from affecting the normal operation of other sections of the target projectile.
[0031] To reduce the impact on the aerodynamic shape of the target missile, the front end of the aerodynamic head cover 1 is generally designed with a drag-reducing shape to reduce the length of the device while adapting to supersonic flight. Multiple light-transmitting holes 6 are evenly distributed along the circumference and length of the aerodynamic head cover 1 to ensure that the energy of the tracer tube 4 can diffuse to the outside of the target missile.
[0032] Furthermore, the pneumatic hood 1 is fitted onto one end of the mounting cylinder 2 and secured with screws. Preferably, a second flange with a diameter smaller than the inner diameter of the tail end of the pneumatic hood 1 is provided at the front end of the mounting cylinder 2, so that when the pneumatic hood 1 is fitted onto the second flange, the outer wall of the pneumatic outer shell formed by the connection with the mounting cylinder 2 is smooth. By connecting the pneumatic hood 1 to the second flange through countersunk screws passing through the outer wall of the pneumatic hood 1, the pneumatic hood 1 and the mounting cylinder 2 are secured, enclosing the tracer tube 4 inside and providing a good aerodynamic shape for the target projectile.
[0033] In an optimized implementation, such as Figure 3 As shown, a clamp 5 is fitted over the tracer tube 4; the clamp 5 is fixed inside the pneumatic housing. The clamp 5 is preferably an elastic C-ring, fitted over the tracer tube 4 and fixed to the pneumatic housing by screws.
[0034] Furthermore, refer to Figure 4A second wiring hole 8 is provided between the clamp 5 and the pneumatic housing. The ignition wire 9 at the front end of the tracer tube 4 passes through the second wiring hole 8 and the first wiring hole 7 and then connects to the cable inside the target projectile. The wiring hole guides and organizes the ignition wire 9 inside the device. The second wiring hole 8 and the first wiring hole 7 are located in the same position, that is, distributed along the length of the pneumatic housing.
[0035] To prevent the tracer tube 4 from moving backward during operation, the base 3 is provided with a tracer tube limiting groove on the side facing the pneumatic housing; one end of the tracer tube 4 is inserted into the tracer tube limiting groove.
[0036] The pneumatic outer shell has a target missile connector at one end near the base 3, which connects the target missile to a rocket or other weapon modified into a target missile.
[0037] In a detailed embodiment, the base 3 is provided with a first flange; the base 3 and the pneumatic housing are connected by the first flange and screws. Specifically, the diameter of the first flange is smaller than the inner diameter of the pneumatic housing, and it is inserted into the pneumatic housing. Countersunk screws pass through the side wall of the pneumatic housing and connect to the first flange to fix the base 3 and the pneumatic housing. The first wiring hole 7 is preferably located between the first flange and the side wall of the pneumatic housing.
[0038] This utility model also provides a supersonic target projectile, including a target projectile body and the aforementioned device for enhancing the radiation intensity of the target projectile; the target projectile body can be modified from a small-caliber rocket, and the device for enhancing the radiation intensity of the target projectile is installed at the head of the target projectile body.
