Application of the modified quasilinearization algorithm to the construction of the contour of turbine blades

摘要

Under the assumption that the contour curve of a turbine blade consists of four parts (the upper curve, the lower curve, the front circle, and the end circle), this paper applies the modified quasilinearization algorithm to construct a blade contour which is continuous and has continuous first derivatives at each junction point. In addition, the requirements of specified overall length and specified thickness are satisfied.
