Abstract
A turbine rotor blade with a brush seal formed between the blade tip and an outer shroud to form a seal for a blade outer air seal. The brush seal includes fibers made from a high temperature resistant material that has long wear life such as fibers of alumina-boria-silicate in order to withstand the temperature environment of a turbine rotor blade and to provide long life due to rubbing of the brush fibers on the relatively rotating brush seal surface.
