某大机动无人机基于飞行任务的敏捷性评估飞行科目设计与仿真

Design and Simulation of Flight Courses for Agility Evaluation of High Maneuver UAV Based on Flight Mission

由于现代空战的特点,根据时间量级分类的单维度的敏捷性评估已经不能满足空战的需求。为了优化控制系统的设计,最大限度地发挥飞机的飞行性能,需要对大机动无人机进行基于飞行任务的敏捷性评估。针对大机动无人机敏捷性评估的特点,从20个标准评估机动任务集中选取了3种与某无人机实际使用相关性较强的飞行任务作为其评估机动,展开了无人机基于飞行任务的敏捷性评估和仿真验证。对选取的3种飞行任务进行了详细的敏捷性评估方法描述,在通用的无人机敏捷性评估仿真环境中对加入非线性飞行控制律的某大机动无人机进行了基于3种飞行任务的敏捷性评估仿真验证,根据评估结果对控制律进行调参,为控制律设计提供指南和优化依据。

Due to the characteristics of modern air combat,one-dimensional agility evaluation based on the time scales can no longer meet the needs of air combat.In order to optimize the design of the control system and maximize the flight performance of the aircraft,it is necessary to evaluate the agility of the high maneuver UAV based on the flight mission.In view of the characteristics of the agility evaluation of high maneuver UAVs,three flight missions were selected from 20 Standard Evaluation Maneuver Set(STEMS)for agility evaluation research based on flight missions.The agility evaluation methods of the selected three flight missions were described in detail.The agility evaluation of the high maneuver UAV based on the particular three flight missions with the non-linear flight control law was simulated in an universal agility evaluation simulation environment.The results of agility evaluation simulation can provide design guidance for control law optimization.
