【摘要】 将在Ｎ－Ｓ方程中加入动量源项以取代桨叶作用的思想应用于共轴式双旋翼的气动力计算。尾迹是用Ｎ－Ｓ方程求解的，故能更好地模拟两旋翼的干扰。计算结果与实验比较表明，该方法能较好地预估共轴式双旋翼的气动特性。更多还原

【Abstract】 The aerodynamic properties of a coaxial rotor configuration are calculated by solving 3 D incompressible N S equations with momentum source terms. Computed aerodynamics and wake geometry are compared with experimental and flight test data respectively. The results show that the aerodynamic properties of coaxial rotors can be well predicted by solving the N S equations with momentum source terms.更多还原
