介绍螺桨转子系统颤振涡动的一种算法，本算法考虑桨叶的振动变形，桨轴─支承系统的振动特性，以及螺桨转子的不平衡力。利用本算法对一模型螺桨转子和一实际螺桨转子进行了分析计算。对螺桨转子轴头动刚度、桨叶弹性变形、桨盘不平衡度等因素对螺桨转子系统颤振涡动的影响进行了分析，表明螺桨转子轴头动刚度下降时，螺桨发生颤振涡动的极限飞行速度下降。模型螺桨转子的计算结果与风洞试验结果相当吻合，证明本算法是正确的。
An algorithm for the flutter vortex of a propeller rotor system is introduced. The algorithm takes into account the vibration and deformation of the blade, the vibration characteristics of the propeller shaft-support system, and the unbalance force of the propeller rotor. Using this algorithm, a model propeller rotor and an actual propeller rotor are analyzed and calculated. The influences of such factors as the head stiffness, propeller elastic deformation and paddle unbalance on the flutter vortex of the propeller rotor system are analyzed. It is shown that the propeller rotor shaft stiffness decreases when the propeller shaft occurs The flutter’s limit flight speed is reduced. The calculated results of the model propeller rotor are in good agreement with the wind tunnel test results, which proves that this algorithm is correct.
