Digitally Optimised Engineering for Services;
HAP3: Engine Wear and Damage Modelling

The aim of the joint project is to develop an overall wear model of current Period
engine generations to predict the influence of wear on the overall efficiency 01.08.2018 – 31.12.2021
of the engine. To this end, wear-intensive individual components and subsys-
tems of aircraft engines are being investigated in realistic thermomechanical Project Director
load tests using specially developed test methods and test stands. Among Prof. Dr.-Ing. habil. Maik Gude
other things, methods are used to investigate the rubbing behavior, enabling
determination of the forces and deformations occurring, the temperatures at Contact Person
the blade tip and the liner material, and the induced blade vibrations (Fig. 1). Dr.-Ing. Christoph Ebert
Furthermore, the wear and damage behaviour is analyzed both on individual Richard Protz
casing plain bearings (Fig. 2) and subcomponents of the overall VSV system
(Fig. 3). The wear and damage behaviour is determined phenomenologically Funding
and compared with real in-service data. The results obtained make it possible University Technology Centre
to reduce the maintenance effort and costs through customisable service in- Rolls Royce plc. (RRD)
tervals and contents. This can significantly improve the energy efficiency and
environmental friendliness of current and future engine generations. Project Partner
