Stochastic Differential Equation Risk Assessment of Considering the Error Distribution of 3-Dimensional Correlation in Free Flight
Zhang Zhao-nin · Science Technology and Engineering · 2013
In order to ensure the safety of free flight,collision risk in free flight was demanded to assessment under the CNS performance environment.With random factors of the flight taken into account,the random input item was introduced on the basis of the aircraft movement deterministic differential equation,and with CNS factor error distribution of 3—dimensional correlation concerned,the collision risk model of the aircraft movement stochastic differential equation in free flight was established.The combined method of Milstein method and finite difference method was used to solve the model.The example analysis verifies the feasibility of the model.
