Parameterized molding design for variable thickness cooling turbine blade

Yue Zhu-feng

Abstract

A new parametric design method of variable thickness cooling turbine blade is proposed based of analytic method of functions.Cubic spline interpolation method is used to get the cooling blade thickness function according to several parametric points defined on the blade profiles.Then,a series of discrete data points on the cooling passage profiles can be calculated according to the blade profiles functions and the thickness functions.Finally,a variable thickness cooling turbine blade model is established through CAD platform.The parametric design of variable thickness cooling turbine blade will lay a foundation for automated design optimization and multi-disciplinary design optimization,and it is helpful and useful to get more high performance turbine blade.
