Aircraft (10), air conditioning systems (12), and air diffusers (14) that may be used to create a quiet, comfortable environment within an aircraft cabin (16) are disclosed. For example, an aircraft cabin air diffuser, which may be used in an air conditioning system and/or an aircraft, may include an inlet section (20), a neck section (30) downstream of the inlet section, an outlet section (40) downstream of the neck section, and a flow controller (50) within the neck section. The flow controller may be a passive pressure controller (70) (configured to affect air flow through the passive pressure controller in response to an air pressure differential across the passive pressure controller) and/or a vortex inducer (72) (configured to create a vortex of air downstream of the vortex inducer). |
