A fixture configured to secure a component in a vehicle includes a panel separating an internal cabin from an external compartment. The panel has a first side facing the internal cabin and a second side facing the external compartment. A hole is disposed within the panel. The component is configured for mounting to the panel via the hole. The component includes a flange configured for abutting the first side of the panel and a coupling feature configured to extend through the hole into the external compartment. A fastener is configured to removably couple with the coupling feature and abut the second side of the panel for fastening the component to the panel.

A passenger cabin air distribution system includes a ventilation system and an ejector-diffuser. The ventilation system is operable to provide a conditioned air. The ejector-diffuser is positioned to receive a flow of the conditioned air from the ventilation system. The ejector-diffuser includes an induction unit and a diffuser section. The induction unit includes a secondary inlet in communication with a cabin air from a passenger cabin and is configured to mix the flow of the conditioned air with an induced flow of the cabin air into a mixed air. The diffuser section includes a discharge to eject the mixed air to the passenger cabin. The diffuser section is shaped to provide for efficient mixing with low backpressure in order to maintain the low motive pressure in the nozzle.

An integrated passenger service unit (PSU) is disclosed. The integrated PSU includes a housing installable into an aircraft overhead panel and a control knob set into, and positionable relative to, the housing. The housing incorporates signage elements (e.g., fasten seat belts, no smoking) visible through its exterior surface, as well as reading lights and gasper outlets set thereinto (e.g., as adjacent segments of an annulus). Each reading light includes an LED array selectably configured to illuminate the corresponding seat, and each gasper outlet directs an airstream toward the seat. The housing includes a notification ring configured to illuminate when the passenger calls a flight attendant. A control knob is set within the housing and positionable relative thereto. The control knob incorporates an LCD display and user interface (UI) which allows the occupant or passenger to view and adjust the status of the reading lights, gasper outlets, and notification ring.

A temperature control system in an aircraft passenger service unit is disclosed. In embodiments, the system includes a swirl chamber configured to receive an inlet air stream, and a vortex tube configured to receive the inlet air stream from the swirl chamber and separate the inlet air stream into a warmer air stream and a cooler air stream. In embodiments, the system further includes a nozzle configured to direct a temperature-controlled air stream into a passenger space of an aircraft; wherein the nozzle is configured to be selectably adjusted in order to selectively blend the warmer air stream and the cooler air stream in order to generate the temperature-controlled air stream.

A ventilation system for ventilating a passenger compartment of an aircraft, an aircraft, and a method of operating the ventilation system are disclosed herein. The ventilation system includes, but is not limited to, a bezel, a fluid vent, an electronic sensor, and a valve. The bezel defines a bezel aperture and the fluid vent defines an axis that passes through the bezel aperture to direct a stream of air through the bezel into the passenger compartment. The electronic sensor is associated with the bezel and is configured to generate a bezel position signal. The valve is configured to vary a flow rate of the stream of air through the fluid vent based on the bezel position signal.

An air gasper (air) for a vehicle includes an air inlet (26), a first housing (24) disposable through a panel in the vehicle (12), the first housing (24) being connected to the air inlet (26), a second housing (70) disposed within the first housing (24), an air outlet (72) disposed within the second housing (70), downstream of the air inlet (26), and a first mechanism (102, 70) connected between the first housing (24) and the second housing (70). The first mechanism (102, 70) permits the second housing (70) to be stowed within the first housing (24) in a stowed position and also permits the second housing (70) to extend outwardly from the first housing (24) in a deployed position.
