| 摘 要： | 大展弦比飞翼布局飞机取消了垂尾和常规方向舵,通常采用大偏角的开裂式方向舵作为偏航操纵面.基于风洞试验数据,研究了开裂式方向舵的偏航操纵非线性、小偏角偏航舵效低、附加力效应显著和3轴操纵耦合等特性,并分析了其偏转对飞机气动特性和稳定特性的影响.总结了开裂式方向舵在各飞行任务阶段下的使用特点,如针对其小偏角偏航舵效低的特性...

| Abstract: | The high-aspect-ratio flying wing eliminates vertical tail and conventional rudder,and uses instead a split drag rudder with large deflection as its directional control surface.Based on wind tunnel test data,the control features of a split drag rudder is discussed,including its nonlinear yaw control,low directional control efficiency with small deflection,strong additional force effects and 3-axis coupling controls;and then the impact of the split drag rudder on the aerodynamic performance and stability fea... |
