Abstract:
An attachment for the air intake of a gas turbine engine comprising an engine housing defining an engine flow passage, the attachment comprising:a plurality of particle separators adapted to be coupled to the engine housing and cooperating to define an attachment axis, the particle separators being spaced circumferentially about the attachment axis, each particle separator comprising a housing defining a separator axis, a first flow passage having at least a portion that is annular, an annular opening, and an annular second flow passage positioned in fluid communication with the annular portion of the first flow passage through the opening, the annular portion of the first flow passage, the opening, and the second flow passage being concentric about the separator axis, the first flow passage and the second flow passage being configured so that inertia of particles entrained in a stream of air flowing through the annular portion of the first flow passage tends to cause the particles to flow from the annular portion of the first flow passage through the opening into the second flow passage to allow the stream of air to enter the engine flow passage from the first flow passage free of the particles removed therefrom, the separator axes being parallel to and spaced apart from the attachment axis.
