Patent ID: 7736407

Claim:
An inertial separator comprising(a) a main duct having a first half and a latter half, the first half, having a positive curvature and a spanwise channel width larger than a radial channel width, the latter half, having a similar aspect ratio and a mean curvature larger than the first half with an outer wall part removed,(b) part for sucking a boundary layer formed on a side of a removed part of an outside wall of the latter half,(c) a final collection part succeeding the part for sucking the boundary layer, the final collection part having an inlet duct, an outlet duct and a curved duct formed between the inlet duct and the outlet duct, the curved duct having a larger mean curvature and a smaller radial channel width than the latter half of the main duct, with an outside wall part removed, and(d) a collection chamber part formed on a side of a removed part of an outside wall of the curved duct of the final collection part; and wherein two ducts succeeding the latter half of the main duct and the outlet duct of the final collection part are connected.
