| 摘 要： | 建立了一种基于优化思想的配平舵偏求解方法,在此基础上对飞行器静操纵性进行了评估.具体采用三通道线性叠加模型,结合多维线性插值和牛顿-拉夫森算法,对大量的飞行器风洞试验数据进行处理,快速准确地求解出各个状态下的配平舵偏.与传统求解方法相比,该方法求解精度不受搜索间隔限制,求解时间大大缩短.通过对求解结果进行分析,评估飞行器的静操纵性,提高了静操纵性的评估效率和准确性.

| Abstract: | An approach of trim rudder solution based on optimization method is established,and static control performance of a vehicle was evalued by this approach.Use three-channel linear superposition model,trim rudder deflection of various state is fastly and exactly solved by multi-dimensional linear interpolation and Newton-Raphson method with mass wind tunnel test data.Comparing with tranditional approach,accuracy is not restricted by search interval and less time is spent.By analysing result of trim rudder defl... |
