水上飞机起降移动安全区定量计算分析

Quantitative Method for Establishing Moving Safety Zone Around Seaplane During Taking-Off and Landing

为保障水上飞机起飞和降落过程中航行的安全,提出一种基于水上飞机与船舶安全会遇的移动安全区边界确定方法。该方法通过分析水上飞机起降阶段的航行及操作特点,以船舶跟驰模型研究机理为基础,构建水上飞机起降时与在航船舶的安全会遇间距模型,并以此建立水上飞机领域模型;根据水上飞机水面爬升操作特征,考虑水上飞机对水面净空高度的需求,构建水上飞机爬升时的安全跨障会遇模型;在结合水上飞机领域模型的基础上,定量界定水上飞机起降移动安全区的尺度。研究结果表明,水上飞机起降移动安全区尺度与水上飞机性能参数、会遇船舶尺度、航向及航速相关。在水上飞机管理应用中,可根据水上飞机机型及应用水域实际交通情况确定水上飞机水面起降移动安全区的尺度。

In order to prevent a seaplane from coming into collision with vessels while taking-off or landing,a calculation method is worked out for determining the size of the Moving Safety Guard Zone around the seaplane. The navigational characteristics of a seaplane while taking-off and landing are analyzed and the model for safe approaching distance is built on the basis of the mechanism of vessels following model. This model establishes the on-water seaplane domain. According to the climbing operating characteristics of the seaplane,with the necessary headroom for the plane to climb up to be taken into account,the model for the distance ensuring safely crossing obstacles is also established. The combination of the two models makes the model of the resultant seaplane domain with which the Moving Safety Guard Zone around a seaplane is quantified. The study shows that the Moving Safety Guard Zone around a seaplane depends on the performance parameters of a seaplane and the side,course,and speed of the concerned vessels. In the practical operation management of seaplane,the scale of Moving Safety Guard Zone of seaplane is determined by the actual traffic situation and the type of involved seaplane.
