Method for calculating damage probability of hedgehopping-and-upper-attacking smart ammunition

Abstract

The invention provides a method calculating damage probability of a hedgehopping-and-upper-attacking smart ammunition, which is used for assessing the terminal damage efficiency of the type of weapon systems and is mainly aimed at assessing the terminal damage efficiency of the hedgehopping-and-upper-attacking smart ammunition when the hedgehopping-and-upper-attacking smart ammunition is used forattacking an armored target on the ground in explosively-formed projectile kill elements. Aiming at the problem that the hit accuracy of the explosively-formed projectile kill elements is simultaneously affected by the relative position between the hedgehopping-and-upper-attacking smart ammunition and the target, and the attitude of projectile bodies at the detonation moment, a formula for computing the damage probability of a single shot is provided, a mathematical model which is used for solving the damage probability of the single shot by using the Monte Carlo method is built, and the damage probability of the single shot is finally obtained. The method provided by the invention is suitable for assessing the terminal damage efficiency of the hedgehopping-and-upper-attacking smart ammunition when the hedgehopping-and-upper-attacking smart ammunition is used for attacking the armored target on the ground in the explosively-formed projectile kill elements.

Description

technical field [0001] The present invention relates to a method for calculating the damage probability of a weapon ammunition to a target, specifically a method for calculating the damage probability of a single shot of a smart ammunition when it hits a ground armor target with an explosively formed projectile in the manner of skimming the top and hitting the top. Evaluate the terminal damage effectiveness of this type of weapon system. Background technique [0002] With the rapid development of modern science and technology, various new concepts of smart ammunition continue to emerge. Since the 1990s, loitering munitions, with the Low Cost Autonomous Attack System (LOCAAS) developed by the United States as a typical product, have become a hot spot in the development of smart munitions in various countries. This type of smart ammunition mainly uses explosively shaped projectile damage elements to precisely strike high-value targets such as ground armored vehicles and missi...

[0007] (4) Large after-penetration effect

[0018] The above formula (1) is difficult to apply to the calculation of the probability of damage to the target by the explosively formed projectile of the skimming top-hitting smart ammunition

Its limitation is that this formula cannot describe the influence of the attitude of the projectile at the moment of detonation on the hit accuracy of the damage element, nor does it involve the coupling of physical quantities such as the flight speed of the damage element and the magnitude and direction of the flight speed of the projectile on the hit accuracy of the damage element.
