ENGINE COMPONENT FOR A TURBINE ENGINE

General Electric Company,...

1. An engine component for a turbine engine, the turbine engine generating a fluid stream, comprising:a particle separator having an inlet receiving the fluid stream, a scavenge outlet emitting a particle-laden stream, and a separator outlet emitting a reduced-particle stream;
a particle collector in fluid communication with the scavenge outlet and comprising a substrate configured to retain at least some of the particles from the particle-laden stream; and
a bypass passage fluidly coupled to the particle-laden stream and defining a fluid bypass around the substrate downstream of the scavenge outlet;
wherein at least a portion of the particle-laden stream contacts the substrate which retains at least some of the particles, and as the substrate fills with particles, the particle-laden stream can bypass the substrate via the bypass passage.
