Environmentally friendly aviation requires reliable aircraft engines with high efficiency, low weight and a long service life. Turbine components made from new materials must be designed so robustly that they exhibit improved properties over the entire life cycle. For future low-pressure turbines (LPTs) subject to higher thermal loads, design concepts for guide stages in SiC/SiC-CMC construction are being developed and their impact behaviour investigated.
Within the framework of the project, methods for defect detection are being developed at the Fraunhofer-Centre HTL and measurements are being carried out on impact samples. The main objective is to develop a procedure based on computer tomography that can be used to detect the damage and material changes in SiC/SiC samples caused by impact. In particular, the damage caused by the foreign body impact and its local distribution are intended to be recorded and evaluated. The microstructures will be described as a function of the impact.
