Abstract
A vane cluster for a turbine engine compressor or turbine includes a shroud 12 with a nonlinear slot 26 extending therethrough to divide the shroud into thermally independent shroud segments 24. The slot is bordered by matching nonlinear surfaces 28 that are easy and inexpensive to produce with conventional wire EDM equipment. The nonlinear profile of the slots effectively resists fluid leakage.
