基于性能需求的战斗机操纵面优先级评估模型

An evaluation model for control surface superiority of fighters based on performance requirements

为了简化多操纵面战斗机的控制分配设计,在保证多操纵面战斗机充分发挥性能潜力的前提下,基于性能需求提出了一种操纵面使用优先级的数值评估模型。通过分析超视距(Beyond Visual Range,BVR)空战、视距内(Within Visual Range,WVR)空战阶段的性能需求,提出了不同飞行阶段下的操纵面优先级评估模型。以典型鸭式布局多操纵面战斗机为例,基于飞机气动数据对各操纵面的优先级参数进行了评估,并对各操纵面对飞行性能指标的影响进行了计算。结果表明,操纵面优先级评估结果与操纵面对飞行性能的影响趋势一致,说明所提出的操纵面优先级评估模型合理且有效。

In order to simplify the control allocation design of multi-control surface fighter under the premise of ensuring the full performance potential of multi-control surface fighter,a numerical evaluation model of control surface priority is proposed based on performance requirements. The flight requirements of different flight phases,including beyond visual range（BVR）,within visual range（WVR） are analyzed. Quantitative evaluation models of control surface superiority of different flight phases are proposed.Taking a typical duck-type multi-control surface fighter as an example,the priority parameters of each control surface were evaluated based on the aircraft aerodynamic data,and the influence of each control surface on the flight performance index was calculated. The simulation results show that the flight performance results coincide with the control effector superiority results,which indicates the control surface evaluation model is reasonable and effective.
