Training order for the documentation of turbine blade repairs for submission to the American Aviation Safety Authority FAA
Support for the introduction of the “Directed Energy Deposition” production technology for the repair of Auxiliary Power Units in Aircraft.
Description
Auxiliary power units (APU) supply compressed air and energy for aircraft. A turbine wheel is one of the core components for generating power.
Modern APUs have a so-called “bladed disk”, also known as a “blisk”, as a turbine wheel.
The upper part of the blisk generally wears down due to erosion.
Directed Energy Deposition (ISO 52900) is used to reapply material to the complex-shaped turbine blades where erosion has led to a deficit.
The project content is to support the industrial partner in the introduction of the production technology and certification of the repair.
