Abstract
A particle deflector for a gas turbine engine deters accumulation of particles in cooling passages of nozzle vanes of the engine. The particle deflector is arranged to be disposed around a turbine housing over cooling passages that supply cooling air to nozzle vanes within the housing. The particle deflector includes circumferentially distributed mounting holes for mounting the particle deflector to the turbine housing. The particle deflector also includes circumferentially distributed spacers to space the particle deflector from the housing.
