Abstract
Sectional profiles close to a tipand a part between a midportionand a hubare shifted to the upstream of an operating fluid flow in a sweep direction. Accordingly, an S shape is formed in which the tipand the part between the midportionand the hubprotrude. As a result, it is possible reduce various losses due to shook, waves, thereby forming a transonic airfoil having an excellent aerodynamic characteristic.
