Abstract:
Analytical and experimental research was conducted to evaluate a ceramic seal system for a high pressure turbine employing plasma-sprayed graded metal/ceramic yttria stabilized zirconium oxide (YSZ). The performance characteristics of several YSZ configurations were determined through rig testing for thermal shock resistance, abradability, and erosion resistance. Results from this work indicate that this type of sealing system offers the potential to meet the operating requirements of future gas turbine engines. However, further development and refinement of this technology, particularly in the area of improving cyclic thermal stress tolerance, is necessary.
