method of control of the boundary layer flow

摘要

An aircraft inlet channel (102) comprising an annular air intake structure defined by an inner surface and an outer surface, a plurality of perforations (110) formed in the outer surface of the inlet channel of aircraft (102), a plenum (202) located within the aircraft inlet channel (102) and configured to receive air entering the plurality of perforations (110), and / or a plurality of sensors (112) disposed around the outer surface of the aircraft inlet channel (102), each sensor (112) being associated with a region of the plurality of perforations (110). Each sensor (112) may include a hot film anemometer. The aircraft inlet channel (102) may further comprise a regulator (204) coupled at one end to the plenum (202) and at another end to a pump (206), the regulator (204) regulating an aspiration produced by the pump (206).
