中文摘要： 未来非常规飞机采用多操纵面布局，其操纵响应过程具有高非线性和强耦合性特点。为减少研制风险，需要在初步设计阶段确定多操纵面效能，建立飞机的动力学模型，进一步预测其动态特性，但是目前尚缺乏有效的试验测试方法。本项目运用实验空气动力学、飞行试验、控制系统设计等多学科交叉的理论和方法，通过飞行试验、数据统计分析、仿真验证等手段，开展动态缩比模型系统与试验方法的综合设计、高精度飞行参数辨识、动态缩比模型飞行试验与风洞试验相关性等方面的研究，力图解决多操纵面联动的操纵输入优化、多耦合动态系统辨识的高质量数据获取、飞行试验与风洞试验的条件差异性规律等关键科学问题。在此基础上，建立基于动态缩比模型飞行试验的操纵面效能测试修正方法。这种新测试方法的形成，对于提高航空器装备研制水平，丰富实验流体力学和飞行试验研究手段，具有科学意义和工程应用价值。

英文摘要： For an untraditional configuration, multi-control surface configuration is always adopted, but the control process is high nonlinearity and nonlinear aerodynamic coupling.In order to release the risk in flight test, at the initial design stage, not only the control surface effectiveness is needed to make sure, but also the dynamic model is to buildand the dynamic performance should be estimated. However, there are still no effective test techniques to introduce.With the theories and methods in multidisciplinary study such as aerodynamic dynamic experiment, flight test and design of control system, combing theflight test,statistical analysis simulation of subscale modeling, this program will develop the research including the integrated design of dynamic flight test of subscale modeling system and experimental method, high precision systemand parameter identification, and relative analysis with wind tunnel. Therefore, to solve the input optimization of multi-control surface linkage, high quality data from the coupling dynamic system and condition different laws between flight test and wind tunnel is the pivotal problem.The control surface effectiveness modified test method is built based on the dynamic flight test of subscale modeling.This new methods developed in this research project will not only prompt the standard of aircraft research, but also provide new techniques to the Experimental Fluid Dynamics and Flight Test technology with significance for science and engineering.
