Anti-low-small-slow-target air-defense missile system for 40-millimeter rocket launcher and interception method

Abstract

The invention provides an anti-low-small-slow-target air-defense missile system for a 40mm rocket launcher and an interception method. A seeker, a battle guiding system, a steering engine, a control cabin, a flight engine, an empennage assembly and a solid rocket launching engine are sequentially connected to form a guided rocket projectile; a ground fire control instrument is fixedly connected to the 40mm rocket launcher and is used for tracking a target, resolving and predicting a target track and providing initial target alignment information for the guided rocket projectile; the solid rocket launching engine is ignited to launch the guided rocket projectile, power is provided by the flight engine after the guided rocket projectile leaves a cylinder, the control cabin takes the initial alignment information as a reference, the real-time position of the guided rocket projectile is calculated, closed-loop control is formed by the real-time position and a predicted target position, and the guided rocket projectile enters a mid-guidance mode; after the target is locked through the seeker, the rocket projectile enters a self-seeking guidance mode, flies to the target and destroys the target through the battle guiding system. According to the anti-low-small-slow-target air-defense missile system for the 40mm rocket launcher and the interception method, the seeker can capture and lock a long-distance infrared characteristic weak target.

Description

technical field [0001] The invention relates to the technical field of small-caliber guided munitions, in particular to an anti-low, small and slow target anti-aircraft missile system for a 40mm rocket launcher and an interception method. Background technique [0002] With the development of information, materials, navigation and other technologies, the technology of small fixed-wing and rotary-wing UAVs with detection, strike and evaluation functions has been developed rapidly. This type of air target is small in size, weak in signal characteristics, and has typical low, small and slow characteristics. It has been widely used in modern land battlefields and has become the main threat to ground personnel and equipment. Equipment poses a very big challenge, and it is also a research hotspot in the field of air defense technology of major military powers in the world. Traditional medium and long-range air defense missiles usually adopt the scheme of medium guidance and termin...

AI Technical Summary

Problems solved by technology

[0004] The original launch method of the 40mm rocket launcher is gunpowder launch. Although the chamber pressure in the barrel will reach more than 80 MPa, the launch energy utilization rate is still very low. Moreover, a large amount of high-temperature and high-speed gas is formed at the end of the barrel. Under the condition of structural layout, the wiring of the projectile electrical system puts forward extremely strict requirements; because the 40mm launch tube adopts the recoilless gun mode, when the 40mm rocket is fired at a shoulder-mounted height and a large angle, the launch flame will bounce off the ground, endangering the shooter Safety, so it is required that the launch angle cannot exceed 30 degrees during launch, which greatly limits the use of the 40mm rocket launcher platform in air defense operations

It is precisely because of the constraints mentioned above that although 40mm rocket launchers have been equipped in large quantities since the 1970s, they have never been equipped with ammunition capable of accurately intercepting moving targets in the air.
