Aspirator mechanism for turbine engine air cleaner

摘要

A known military tank is powered by a turbine engine having a large capacity air filter unit; a fan is ordinarily employed to draw dust-laden air from the filter unit. Erosion of the fan blades by fast-moving dust particles is a problem. We have substituted for the fan an aspirator mechanism; fast moving combustion products flowing through the engine exhaust duct draw dust-laden air from the filter unit through a slot-like orifice in one wall of the duct.
