Large-caliber supersonic target projectile for testing or training

Abstract

The invention relates to a large-caliber supersonic target projectile for testing or training. The large-caliber supersonic target projectile comprises a rocket engine and a target projectile, wherein the rocket engine comprises a combustion chamber, a jet tube and a plurality of fins; the front end of the combustion chamber is connected with the target projectile, and the back end of the combustion chamber is connected with the jet tube; the fins are distributed on the outer circumference of the jet tube; the target projectile comprises a shell, a counterweight body and a counterweight ring; the shell has a hollow structure; the counterweight body is embedded and fixed at the inner front end of the shell; and the counterweight ring is arranged on the middle part of the shell, and is fixed by using a preset separation blade. According to the large-aperture supersonic target projectile, on one hand, the gunpowder loading structure and gunpowder loading scheme of the rocket engine are improved, so that the thrust force of the engine is increased; on the other hand, the weight of a head structure is reduced, so that a high launching speed is achieved for the complete projectile; and target characteristics such as geometry, speed, infrared rays, radar reflecting area and the like at the final flying stage of a cruise missile can be well simulated, so that the requirements of testing or training on the similarity, economy and repeatability of a simulated target are met.

Description

technical field [0001] The invention relates to a beacon for radar performance debugging and detection, in particular to a large-diameter supersonic target missile capable of simulating the characteristics of cruise missile-related targets, and belongs to the technical field of simulated target missiles for testing or training. Background technique [0002] At present, the targets used in domestic and foreign interception cruise missile training and joint debugging tests of ultra-short-range anti-missile weapon systems generally adopt the following methods: [0003] 1. Aircraft release method [0004] This is a traditional method for testing precision-guided weapons, which is characterized by strong intuition, but also has many shortcomings, such as: high cost; difficult to control the flight trajectory and landing point; high requirements for the test field area; The scope of application is limited and the risk is high. [0005] 2. Rocket Prying [0006] Build a special ...

AI Technical Summary

Problems solved by technology

[0010] The aircraft model substitution method is cheap, reusable, and can better simulate the geometric characteristics of cruise missiles, but its disadvantage is that the speed is too low to simulate the speed characteristics of cruise missiles;

[0011] In summary, the existing alternative target methods are difficult to meet the requirements of test or training for the similarity, economy and repeatability of simulated targets
