Abstract:The bowed twisted blades have been widely used in the developed countries in the 1990s, such as the USA and UK. In China,this new type blades are also successfully applied to the steam turbines, and the application of these blades to gas turbines of air engines has had a good beginning. The effectiveness of applying the bowed twisted blades to turbines demonstrated by the tunnel and static experiments is discussed, and the mechanism of reducing the radial and cross secondary flow losses by using the bowed twisted blades is analyzed in this paper. The advances in research on compressor bowed blades and key problems in this research are considered shortly. Based on design experiences, several principles for designing stages with bowed twisted blades are summarized in the end of this paper.
Keywords:bowed-twisted blade  secondary flow  cascade aerodynamics
