Seal Technology in Gas Turbine Engines

The papers were grouped into six sessions Survey, Material Technology, Users View of Seal Technology, Measurements of Seal Behaviour, Laboratory Experiments, and Design Aids. The meeting was concluded with a Round Table Discussion. This discussion as well as those after each presentation, and the Technical Evaluation Report are included in the Conference Proceedings. The purpose of the meeting was to provide a forum to discuss technology of gas turbine engine seals. The discussion was limited to cases where relative motion exists between parts of seals. Both gas path and oil path seals were covered. Due to relevant and timely contributions an overview on the present status and the shortcomings of seal technology is reached as well as on the current developments. Various aspects were taken into account like engine operating and maintenance costs, and the engine design procedure. Within the Round Table Discussion and even more extensively in the Technical Evaluation Report conclusions are drawn and recommendations are given whereto future interest should be directed.
