| 摘 要： | 针对近距编队飞行面临的相互气动影响问题,采用等效气动效应法建立了尾流气动影响的等效模型.该模型可引入编队飞行六自由度方程.通过仿真验证表明,由等效模型计算出的诱导力与诱导力矩和风洞数据具有较好的符合度,等效模型可直接用于编队飞行建模及控制器的设计与仿真.

| Abstract: | A mathematical representation of the aerodynamic effects in close formation flight is presented.The model can be incorporated in six-DOF equation of formation flight.The simulation and comparison study of the aerodynamics have been presented,which shows that the computed induced forces and induced moment model match well with the windtunnel data.The equivalent model can be applied directly to formation flight modeling,and controller's design and simulation. |
