【摘要】：针对基于Reich模型的平行航路侧向间隔碰撞风险评估过程中,机型尺寸与巡航速度对评估精度产生影响这一问题,引入改进后的椭柱型模型对基于甚高频全向信标(VOR)导航台的平行航路下飞行器侧向碰撞风险进行仿真建模分析。首先确定影响空域安全性评估的各参数间的关系,再根据飞机侧向偏航距离的分布规律,应用新模型分析得出碰撞风险的发生概率。采用实际飞行数据进行仿真实验,在给定航路距离、机身相对距离、偏航距离的情况下,对VOR导航下两机侧向碰撞率分析得出:当机身长度提高57.1%时,碰撞风险提高了47.7%;而当巡航速度提高4.8%时,碰撞风险增加了7.6%。实验证明利用该方法能够分析航空器尺寸及航行速度对航路碰撞风险的具体影响,进而可在满足安全目标水平条件下缩小最小安全间距,提高空域利用率。
[Abstract]:In the process of side collision risk assessment based on Reich model, the model size and cruise speed have an impact on the evaluation accuracy. An improved ellipsoid model is introduced to simulate and analyze the lateral collision risk of aircraft under parallel routes based on VHF omnidirectional beacon (VHF) navigation station. First, the relationship between the parameters affecting the airspace safety assessment is determined, and then the probability of collision risk is obtained by using the new model analysis according to the distribution of the aircraft lateral yaw distance. Using the actual flight data to carry on the simulation experiment, under the given route distance, the fuselage relative distance, the yaw distance, the analysis of the two aircraft lateral collision rate under the VOR navigation: when the fuselage length increases 57.1%, Collision risk increased 47. 7%, while when cruising speed increased 4. 8%, collision risk increased 7. 6%. The experimental results show that this method can be used to analyze the impact of aircraft size and navigation speed on the collision risk of air route, thus reducing the minimum safety distance and improving the utilization rate of airspace under the condition of satisfying the level of safety target.
