Abstract
A booster-compressor assembly for supercharging air into a core engine that powers propellers of a turboprop aircraft engine includes an asymmetric annular booster duct aft of the propellers and disposed about a centerline with at least one symmetric annular rotor section with a row of rotor blades disposed therein. The booster duct has a booster flowpath that includes a core flowpath to a core engine inlet and a bypass flowpath around the core engine inlet and the flowpaths circumscribed about the centerline and not symmetric with respect to each other. A low bypass flow rate means sets the airflow through the bypass flowpath such that a bypass flow rate per unit area through the bypass flowpath is substantially less than a core flow rate per unit area through the core flowpath.
