Combining momentum theory and vortex theory, rotor circulation equation was deduced. The rotor down-wash flow field was calculated using generalized down-wash flow model.
结合动量理论和涡流理论，推导了桨叶环量方程，用广义尾流模型计算了旋翼下洗流场。

It is shown that there will be a revisional term in the generalized angular momentum theorem.
结果表明，与通常的角动量定理比较出现了修正项。
