The effects of turbomachinery blade bow and sweep on aerodynamic loading distribution of the blade are investigated.

研究叶轮机叶片的弯扭及掠形等因素对叶片气动负荷分布的影响。

Based on the generalized dynamic inflow theory and classic non-steady aerodynamic loading theory, a real time model is obtained by establishing wake distortion and decay.

在广义动态入流理论的基础上，基于经典非定常气动载荷理论，建立了尾迹畸变和尾迹耗散的实时分析模型。

Thus, the aerodynamic performance of stage is im-proved obviously, the profile loss decreases through using the "after loading" blade.

优化的“后部加载”叶型明显提高了气动性能，降低了叶型能量损失。
