Both panel method and lifting surface method can be used to calculate the unsteadyforce.
非定常力可以采用面元法或升力面方法计算得到。

In addition, the wake interaction of upstream blade row and the expansion wave at rotor exit also cause an unsteadyforce acting on the downstream rotor blade surface.
此外上游静子尾迹以及动叶尾缘出口膨胀波等也是产生转子叶片表面非定常力的因素。
