Benchmark of Technologies for Small Blisk/Blades Machining

Which technology combination is the most suitable for manufacturing reduced rotor diameters?


Challenge and Motivation

  • The by pass ratio of the next aero engine generations will increase.
  • The core engine will become smaller compared to current engine programs.
  • New challenges for all machining processes result from the new design.


  • Examine the manufacturability of Blisks with smaller Blades and reduced gaps in the framework.
  • Investigation of scaling effects for the different manufacturing processes.
