【摘要】 飞翼布局飞机由于取消了常规安定面,导致其稳定特性发生了很大的改变。针对所建立的大后掠飞翼模型,给出了一套典型的操纵面布置方案,通过CFD计算后,对各舵面气动特性进行了分析,在升降舵、副翼和阻力方向舵偏转过程中对各气动参数的影响进行了研究,给控制系统的设计提供了依据。同时,研究了开裂式阻力舵开裂后引起的纵横航向耦合运动及其控制情况。更多还原

【Abstract】 Due to lack of the routine stabilizers,the stability characteristics of the flying wing changed a lot.Dealing with the high sweepback flying wing,the classical layout of the control surfaces is given,after the CFD computes,the dynamic characteristics of the control surfaces are analyzed,the variation of the dynamic parameters caused by the deflection of the elevator,aileron and the split-drag-rudder(SDR) are studied to provide a reference to design the control system.Further,the coupled motion of the flying wing and the deflection of the control surfaces are studied after the split-drag-rudder(SDR) opened.更多还原
