By minimizing the distance between the rotating vanes of a turbine and the static case structure housing the rotating blades, a client seeks to improve the efficiency of jet engines. Eliminating system leakage is essential to providing the most amount of energy for the lowest cost. The compressor fans of a turbine engine must maintain extremely tight tolerances to reduce leakage around the vanes. Minimizing leakage, a critical task given the smaller features of the vane and rotor geometry, is a particular challenge because of the jet engine’s high pressures and temperatures.
