ABSTRACT:
A supply air ventilation system for providing symmetrical airflow distribution in the cabin of an aircraft, while avoiding excessive flow velocity. The ventilation system includes a supply duct (106) from which pressurized supply air is delivered through a first nozzle (118) at a relatively higher velocity and lower flow volume than through a second nozzle (110). Air flowing through the first nozzle attaches to a surface (132) of an overhead storage bin (16) that curves downwardly into the cabin (12) of the aircraft due to the Coanda Effect, and mixes with the lower velocity higher volume air flowing through the second nozzle, thereby carrying it downwardly into the aircraft cabin.
