基于能量机动性的飞机性能评估方法研究

Study of aircraft performance evaluation method base on energy maneuverability theory

具有自主空战能力的飞机进行机动意图生成时,需以飞机当前状态的基本飞行性能信息为输入,并基于飞机的机动能力对机动意图的可达性进行评估。基于能量机动性理论,通过提出能量机动性模型建模方法,研究了基于模型的飞机飞行性能评估方法和机动意图可达性评估方法,为自主空战飞机生成合理机动意图提供必要的数据支持。同时,以试验机的试飞数据为基础,对建模方法、性能评估方法和机动意图可达性评估方法分别进行了对比验证,证明了以上方法的可行性。

When an aircraft with autonomous air combat ability generates the maneuver intention,the aircraft's basic flight performance in current status should be used as the input information,and the reachablility of the maneuver intention based on the maneuverability of aircraft should be evaluated.Based on the theory of energy maneuverability,an energy maneuverability modeling method is proposed to study the model-based aircraft flight performance evaluation method and the reachability evaluation method of maneuver intention,which would provide a necessary data support for the autonomous air combat plane to generate a reasonable maneuver intention.At the same time,based on the flight test data of the test aircraft,the comparison and evaluation of the modeling,performance evaluation and maneuver intention evaluation methods show their feasibility.
