With the rapid development of the aviation market and the increasingly busy airspace operations,the operation of domestic routes has formed the operation characteristics of crossroutes.Cross-routes have become a high-incidence area for flight delays,flight congestion and safety accidents.The structural advantages and disadvantages of cross-routes have also become the most direct factors that affect the safety and efficiency of aircraft operations on the route.In order to ensure the safe operation of the aircraft on the cross route,this thesis studies the collision risk of the aircraft on the cross route,aiming to calculate and evaluate the collision risk of the aircraft on the cross route.This thesis firstly studies the operation modes of aircraft in two cross-routes,and analyzes the collision risk classification standard of aircraft in the route operation phase and the influencing factors of aircraft collision risk in the route.In order to effectively and reasonably evaluate the collision risk of the aircraft during flight,after comparing and in-depth research on various Event collision risk models,a mathematical model was constructed from the perspective of quantification,and a new two spliced elliptical cones were proposed.Body Event collision risk model.Secondly,the improved Event collision risk model is applied to two different intersecting routes,and the collision risk calculation formula,the area size ratio formula of the collision box,the probability theory double exponential distribution and other mathematical methods are used to calculate the collision of the aircraft on the two intersecting routes.risk.Then,passenger aircrafts such as A380 were selected as examples to calculate the collision risk value of the aircraft in the two intersecting routes calculated by using the improved and pre-and post-Event collision risk model.The results show that the collision risk value calculated by the improved model is reduced,which proves the effectiveness of the improved Event collision risk model.Finally,with the help of the route collision risk theory and using the Matlab language,an application software that can calculate the collision risk of the aircraft in the cross route accurately in real time is developed,and the collision risk of the aircraft in the intersection route is quantitatively analyzed and evaluated.The software can calculate the collision risk of a specific aircraft in a specific cross-path in real time by selecting the cross-path and inputting the parameters of the aircraft and the air-path.
