...M. Vaezi; D. Safaeian; C.K. Chua Purpose Conventional investment casting of turbine blades is a time consuming and expensive process due to the complications in wax injection steps and the complex shape of airfoil surfaces. By using rapid investment casting, a substantial improvement in the gas...

...Haihua Wu; Dichen Li; Nannan Guo Purpose The purpose of this paper is to develop a novel process of integral ceramic molds for investment casting of hollow turbine blades. Design/methodology/approach At first, a resin pattern of a hollow turbine blade prototype is fabricated...

... of the fabrication of Si₃N₄ burner arrays for gas turbine reheat applications is demonstrated. The design of burner arrays features internal fuel passages and integrated fuel injection elements, which cannot be manufactured by conventional methods. Geometrical decomposition of design models...
