초록

An aero-acoustic aviation engine inlet with a single air blowing slot or multiple air blowing slots flows air over one or more segments of inlet acoustic lining surfaces at speeds that are higher than the inlet mean air flow speed, for aggressive inlet noise abatement.

청구항

I claim: 1. An inlet for an aviation engine, comprising: a lip surface of the inlet; an interior surface of the inlet extending inward from the lip surface inside the inlet; a first acoustic lining segment positioned downstream from the lip surface and a second acoustic lining segment positioned downstream from the first acoustic lining segment, each of the first and second lining segments having an exposed surface defining a portion of the interior surface of the inlet; a first annular blowing slot positioned immediately upstream from the first acoustic...
