【Abstract】 It is suggested that the surface of mixed flow turbine blade should been fitted by a surface of double cubic B spline. The profile of turbine blade can then be reproduced by using this procedure and the equation of curved surface of the blade can be given in detail, providing a great convenience for CNC processing of the blade.更多还原
