Abstract

This paper describes a finite element analysis procedure adopted at Volkswagen during the development of a turbine nozzle design with a turbine inlet temperature of 1623 K. The analysis considered only the transient stress problem and not long term ceramic material problems such as oxidation. A reference analysis detected two areas of critically high stress, the shrouds and the trailing edge. This agreed with experimental test findings. Independent solutions were found to overcome these problems by analysis assisted redesign cycles.
