基于ADS-B监视技术的飞行器纵向最小间隔研究

为解决航路飞行安全问题,提高碰撞风险检测的精确度,主要研究飞行器在平行航路飞行过程中纵向安全间隔的问题。对传统的EVENT碰撞模型进行改进,建立以椭圆柱体为碰撞模板的EVENT模型。介绍了广播式自动相关监视(ADS-B)技术的性能及应用背景,并在改进EVENT模型基础上提出基于ADS-B监视技术下各个参数的计算方法。以中航工业石家庄飞机工业有限责任公司小鹰500机型为模型算例,计算出其最小安全间隔。研究结果符合国际民航组织的飞行安全指标,可为研究基于ADS-B监视技术的风险分级提供一种有效方法。

Longitudinal minimum interval of aircrafts based on ADS-B monitoring technique

The problem of longitudinal safety interval of aircraft during parallel air route flight is discussed in order to solve the problem of flight safety and improve the accuracy of the collision risk. The traditional EVENT model is improved by using elliptic cylinder as the collision template. The performance and application field of broadcast automatic monitoring (ADS-B) are introduced, and based on the improved EVENT model, a method for calculating the parameters through using ADS-B monitoring technology is put forward. Taking E500 aircraft as a model example, the minimum safety distance is calculated. The results are in line with the international civil aviation organization''s flight safety index, which provides an effective method for the study of risk classification based on ADS-B technology.
