基于三角模型的机场拦阻功能评估

机场工程应用中，拦阻系统是飞机滑出跑道时的重要安全保障，评价拦阻系统功能的有效性与可靠性对保证飞机安全尤为必要。以舰载机拦阻索为主要研究对象，将拦阻系统在拦阻飞机过程中的具体功能分为阻碍功能、缓冲功能、导向功能等，分别对以上三项功能建立量化指标，采用函数分析方法确定不同指标量化数值，与权重组合得到相应指标评价值；最后结合三角图论构建模型对拦阻系统进行综合评价，分析拦阻系统功能变化趋势，确定具体评价结果。以某机场拦阻系统为例，收集拦阻过程各项数据进行实例分析。评价结果表明：利用所建立的拦阻功能评价方法，可得到拦阻系统在具体拦阻过程中的各项功能评价数值，其中拦阻系统阻碍功能、非缓冲功能、非导向功能所得值依次为0.83、0.46、0.64，根据结果对拦阻系统有效性和可靠性变化趋势做出判断。研究结果可为拦阻系统功能作用评估提供参考依据。

Airport arresting function evaluation based on triangle model

In airport engineering, an arresting system is an important safety guard for an aircraft in case it slips out of the runway. It is particularly desirable to evaluate the validity and reliability of the arresting system to ensure the safety of aircraft. In this paper, carrier-based aircraft arresting cable is the main research subject. The arresting system is divided into three parts with specific functions in the process of arresting an aircraft: blocking function, buffering function, and guiding function. Quantitative indexes are established for the three functions, and mathematical function analysis method is used to determine the quantitative values of different indexes. Using the weight, the corresponding index evaluation values are obtained. Finally, using the triangle graph theory, the trend of the arresting system functions is analyzed to determine evaluation results to comprehensively evaluate the system. Taking an arresting system in an airport as an example, data is collected and evaluated during an arresting process. The results show that using the method for model evaluation function established in this paper, the evaluation values of various functions of the arresting system in a specific arresting process can be obtained. The values for blocking function, nonbuffering function, and nonguiding function are 0.83, 0.46, and 0.64 respectively, and can be used to judge the change trend of validity and reliability of the arresting system. The research results can provide reference for functions of the arresting system evaluation.
