Abstract
An attachment for the air intake of a gas turbine engine includes a plurality of particle separators. The particle separators cooperate to define an attachment axis and are spaced circumferentially about the attachment axis. Each particle separator includes 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. The first and second flow passages are 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 through the opening into the second flow passage to allow the stream of air to enter the engine flow passage free of the particles removed therefrom. The separator axes are parallel to and spaced apart from the attachment axis.
