基于模型的民航客机碰撞安全性研究
摘要
Abstract
Considering the fact that most civil aviation aircraft have a single wing,the traditional Event model has been improved by replacing the original rectangular collision box with a combination of a small cuboid and two small pyramids,which is closer to the actual fuselage shape and reduces model redundancy.Based on the improved collision box,collision risk calculation formulas for the lateral,longitudinal,and vertical directions of the fuselage have been derived.Through the calculation and analysis of examples of mainline and regional aircraft,it is found that the collision risk value of the improved collision model is significantly lower than that of the traditional Event model,with a minimum reduction of about 57%of the traditional model and an average of about 76%,and meets the safety target level stipulated by the International Civil Aviation Organization(ICAO).The quantitative assessment of collision risk using the improved model is more reasonable and accurate.关键词
