流线型变截面叶片设计

STREAMLINED VARIABLE CROSS-SECTION


应用空气动力学等弦长理论,结合相对线速度原理,叶根到叶尖逐渐变窄、变薄,受力更平衡,送风更均匀,且中心无空洞。

Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows and thins from root to tip till tail then widen,the air is more even and uniform.
