摘　　要：科学的复杂飞行动作评估方法能够充分客观的评价飞行员的驾驶水平,对分析飞行员操纵过程和提高飞行训练效率具有重要意义。文中针对复杂飞行动作提出了一种基于语义模式距离的动态时间归整评估方法,首先,通过分解复杂飞行动作构建飞行状态矩阵,利用飞行状态距离改进动态时间归整算法,提高评估速度;然后,根据密度峰值聚类算法自动推算等级评定区间实现复杂飞行动作的评估。经仿真实验验证,该方法具有效好的可扩展性,并且可以针对飞行员进行个性化的复杂飞行动作快速评估。Scientific complex flight action evaluation method can fully and objectively evaluate the pilot’s flying level,which is of great significance for analyzing the pilot’s control process and improving the efficiency of flight training.A dynamic time integration evaluation method based on semantic mode distance is proposed for complex flight actions.Firstly,the flight state matrix is constructed by decomposing complex flight actions,and the flight state distance is used to improve the dynamic time integration algorithm to improve the speed of evaluation.Then,on the basis of the density peak clustering algorithm,the grade evaluation interval can be calculated automatically to realize the evaluation of complex flight movements.Simulation results show that the proposed method has good scalability,which can be applied to evaluate the complex flight actions of individual pilots.
