Abstract
A multichannel particle separator for use in cleaning engine inlet air is disclosed. The separator uses a plurality of channel assemblies arranged in parallel side-by-side fashion within a substantially rectangular housing. Separation of undesired particles is achieved by accelerating the incoming airstream to a high velocity and turning it such that inertia carries the dirt particles into a particle collection chamber. A small percentage of the incoming air is used to induce particulate matter to proceed into the particle collection chambers. Heated air from a source within the adjacent engine is passed along passages within the interior of each channel assembly to heat the surface thereof and prevent ice formation thereon when operating under adverse meteorological conditions. The small percentage of diverted incoming air and the spent hot air are combined in the particle collection chambers to form a turbulence generator which maintains the separated particulates and collected moisture in suspension for exhaustion overboard through a common scavenge manifold.
