中文摘要：

基于刚性动网格的技术，选用B—L湍流模型，利用有限控制体积法对N—S方程进行数值离散，对76°大后掠三角翼的受迫俯仰滚转耦合运动进行了数值模拟，在此基础上，对俯仰滚转耦合运动的气动力特性和流场结构进行了分析。计算结果表明：俯仰滚转耦合运动时，三角翼上表面的涡分布的非对称性将产生横侧方向的偏航力矩和滚转力矩，滚转力矩和偏航力矩随着滚转振幅角和滚转缩减频率的增大而增大，但对法向力影响不大。

英文摘要：

Based on the rigid moving grid technique, the N-S equations with B-L turbulence model are dispersed with finite-volume scheme method. The movement of a coupled-forced pitching and rolling delta wing is investigated. The aerodynamic characteristics and flow-field are analyzed. The calculated results demonstrate the unsymmetrical vortex causes rolling moment and yawing moment. The rolling moment and yawing moment will augment with the rolling frequency and rolling amplitude increasing. The normal force will not be affected.
