自由飞行是解决航路拥挤问题的一种有效方式,因此在自由飞行环境下对飞行碰撞风险进行研究显得尤为重要。分析了在自由飞行空域中实施飞行冲突解脱策略后的转弯航路碰撞风险;考虑了所需通信、导航和监视性能以及飞行速度偏差,建立了基于冲突解脱的碰撞风险评估模型。通过算例分析了冲突解脱角度、水平间隔与飞行碰撞风险之间的关系,结果表明碰撞风险评估模型能很好地对自由飞行空域中实施冲突解脱后的碰撞风险进行评估,验证了模型的可行性。
Free flight is an effective way to solve the problem of overcrowding, so it is very important to study the risk of collision in free flight environment. The collision risk of turn route after the implementation of flight conflict release strategy in free-flight airspace is analyzed. Collision risk assessment model based on conflict release is established considering the required communication, navigation and surveillance performance and flight speed deviation. The relationship between conflict release angle and horizontal collision risk is analyzed through a numerical example. The results show that the collision risk assessment model can well evaluate the collision risk of free flight airspace after collision release, and verify the feasibility of the model Sex.
