Study On Damage Evaluation Of Airstrip By Submunition

Airport runway is an important infrastructure of the airport and an important target in military operations.Using shrapnel hit the airport runway is one of the commonly used method,this paper researches on the damage assessment of shrapnel of airport runway,bullet scatters play outside ballistic model is established and shrapnel damage efficiency calculation model of airport runway,shrapnel of airport runway damage effectiveness evaluation system is developed,has higher application value.Based on the analysis of the target vulnerability of airport runway,the structural composition and structural functional characteristics of airport runway are analyzed,the blocking mode of airport runway is discussed,the blocking criterion of airport runway is given in combination with the minimum take-off and landing window,and the damage level of airport is classified.The external ballistic calculation model of the anti-runway bullet is established,and the coordinates of the landing point and the terminal velocity of the anti-runway submunition are calculated by using the fourth-order Lonze Kuta method.A numerical simulation model of the damage effect of anti-runway bullet on airport runway was established.The judgment method of airport runway block is given,the calculation model of damage efficiency of anti-runway submunition against airport runway is established,and the damage efficiency evaluation system of anti-runway submunition against airport runway is developed.The effects of projectile’s projectile altitude,projectile velocity and projectile CEP on the blocking probability of airstrip are analyzed by using the damage effectiveness evaluation system.The research in this paper has a certain reference value for the evaluation of the damage effectiveness of the submunition striking airstrip and the formulation of the battlefield strike scheme.
