Blisk blades manufacturing technologies analysis
Procedia Manufacturing, 2019 The paper presents blisk blades manufactured by different manufacturing processes. In this sense, different milling trajectories are presented, and, super abrasive machining strategies and EDM technologies are also tested. Machining times, costs and surface finish are analysed in order to determine optimal machining process for blisk manufactured in ...

Various techniques for manufacturing integrally bladed turbine disks (turbine blisks) are described, followed by a discussion of the development trend of turbine blisk manufacture. Analysis shows that powder metallurgy near‐net‐shape hot isostatic pressing will be the focus of future research for turbine blisk blanking, while electrical discharge ...

A study on design optimization for compressor blisks
International Journal of Turbo & Jet-Engines, 2022Abstract Bladed disks are important components of gas turbine engine. Rotor disk spool drum assemblies of gas turbine engine constitute 20–25% of total engine weight. Increasing thrust-to-weight ratio and engine life is paramount for designers.

Turbine blisks designed for advanced liquid rocket engine turbopumps are usually of a timed structure with twisted blades, and they can be machined effectively with the electrical discharge machining (EDM) process. After the machining specifications have been designated, the EDM process of a turbopump turbine blisk is discussed, in which the kernel ...

The thickness mistuning of coatings and blisks cannot be predicted before manufacturing process, and the mistuning patterns normally tend to be random, which has not been investigated in opened studies. A novel finite element model (FEM) is developed to incorporate variable thicknesses of the coatings and the blisks.
