The conclusion that the forward skewedrotor has a higher efficiency and wider off design performance is validated once more.
验证了前弯叶片相对直叶片提高效率、扩大稳定工作范围的实验结果。
2
The boundary layer thickness of the forward skewedrotor decreases in the top of blade due to reduction of the secondary flow loss. This fact conforms with experimental investigation.
得出了叶片周向前弯后， 叶顶部分的附面层减薄， 二次流损失减小的结论， 与实验结果吻合；
3
It can ensure tidiness of groove shape for skewedrotor, accordance of the sheets tilted and easy to insert these conducting bars with the manufacturing process of inserting stamping sheet.
