基于决策场和动力学的航空器搜寻区域划设

Planning Method of Aircraft Search and Rescue Area Based on Decision Field and Dynamics

在失事航空器信息条件缺省的情况下,定位航空器搜寻区域对开展后续救援工作极为重要,为提高定位准确率,通过决策场的相关理论,对迫降过程中飞行员的应急行为决策进行分析,从而提出了一种耦合飞行员应急行为决策和飞行动力学的航空器搜寻范围划设方法。在此基础上,根据高高原地区的气象地形条件建立飞行环境,以B737-700机型为例,在考虑飞行员决策结果差异的情况下,对部分信息条件缺省的航空器迫降飞行过程进行模拟,并据此确定搜寻区域的范围和优先级。仿真结果表明在不稳定因素干扰或信息缺省的情况下,耦合飞行员应急行为决策和动力学模型的搜寻范围划设方法是可靠的。

When the information conditions of the crashed aircraft are default,locating the aircraft search area is extremely important to carry out the follow-up rescue work.In order to improve the positioning accuracy,through the relevant theory of the decision field,the pilot s emergency behavior decision-making during the forced landing process was analyzed,and an aircraft search range setting method that coupled the pilot s emergency behavior decision-making and flight dynamics was proposed.On this basis,the flight environment was established according to the meteorological and topographical conditions in the high plateau area.Taking the B737-700 model as an example,taking into account the differences in the pilot s decision-making results,the forced landing flight process of the aircraft with some default information conditions was simulated.The scope and priority of the search area were determined accordingly.The simulation results show that in the case of unstable factors or default information,the method of coupling the pilot s emergency behavior decision-making with the dynamic model is reliable.
