Research on Runway Blockage Probability through Simulation

The damage and blockade of airport runways are important objectives in modern warfare. The minimum takeoff and landing window is regarded as the damage criterion of an airport runway. On the basis of Mathematica, a simulation is performed by judging whether the inequality group has a solution domain. An improved algorithm for judging whether an airport has a minimum takeoff and landing window is proposed. The algorithm is used to calculate and analyze the blockade probability of an ordinary missile to an airport and the influence of the performance of a guided submunition on the blockade of an airport runway. Results show that increasing the number of submunition, reducing the circular error probable of submunition, and increasing the number of subprojectiles can increase the blocking capability of submunition, while increasing the dispersion radius of subprojectiles will first increase the blocking probability and then decrease it. Through simulation, the inflection point of the blocking efficiency of submunitions is found. This article improves the judgment formula of takeoff and landing window, Compared with the window scanning method, the proposed method solves the problems of error caused by excessively large scanning step and extremely long calculation time caused by considerably small scanning step.
