摘要
阐述了新型低噪声通风机的设计计算方法。
A new type of fan with no surging characte ristics is developed. The aerodynamic theory for three dimensional flow and internal encircling control along blade surfaces have been used. The design and calculation methods and the control principle of the new advance for no surging working ranges at zero flow were clarified.
