Air distribution nozzles, aircraft that include air distribution nozzles, and/or methods of utilizing air distribution nozzles are disclosed herein. The air distribution nozzles include an elongate inlet chamber, an elongate outlet chamber, a tapered elongate slot, an inlet port into the elongate inlet chamber, and an elongate outlet port from the elongate outlet chamber. The elongate inlet chamber extends along an inlet chamber length. The elongate outlet chamber extends along the inlet chamber length. The tapered elongate slot extends between, and fluidly interconnects, the elongate inlet chamber and the elongate outlet chamber. The inlet port is configured to receive an inlet fluid flow along an inlet flow axis. The elongate outlet port is configured to discharge an outlet fluid flow along an outlet flow axis that is oriented at a skew angle relative to the inlet flow axis.

Disclosed is a stowable airflow diverter for removable attachment to a floor vent of a turbine aircraft. The air diverter comprises vertical ducting extending from a base. A flexible gasket and magnets are attached to the base for engagement with the floor vent. A nozzle attached to the vertical ducting redirects the airflow emanating from the floor vent from horizontal to vertical in order to direct air conditioned air into the cock pit of the aircraft. In an alternate embodiment, the nozzle is rotatable with respect to the vertical axis of the duct. In another alternate embodiment, the nozzle and vertical duct comprise telescoping segments such that the device can be collapsed into the floor vent.

Airflow control devices are provided that may be employed in passenger transport vehicles (e.g., passenger transport aircraft, trains, buses, automobiles and the like) that allow individual passengers to selectively control direction and volume of incoming airflow to thereby enhance passenger comfort. According to certain embodiments, passenger airflow control devices are provided with an open-ended domed shell, a receiver immovably fixed to an upper end of the shell and a central air distributor assembly operatively connected to the receiver for receiving an incoming airflow and discharging the airflow to a passenger. The central air distributor assembly may include a central distributor bowl which defines a laterally oriented airflow discharge opening, a central disk which is positionally fixed to and closes a lower end of the central distributor bowl, and an air distributor hub having a lower end immovably connected to an upper end of the central distributor bowl and an upper stem having an air inlet cutout which is received within and rotatably connected to the receiver.

A direction controlled service apparatus may include a mounting assembly, a housing assembly configured to operably connect to the mounting assembly, the housing assembly being movable with respect to the mounting assembly, and a plurality of actuators connected between the mounting assembly and the housing assembly, each actuator of the plurality of actuators being configured to contract upon a current being applied to the actuator to rotate the housing assembly with respect to the mounting assembly.

A unified passenger service unit (PSU) control concentrically incorporates a reading light, a gasper outlet, and a notification ring within a control knob rotatable or pushable (via a pushbutton or the control knob itself) by an occupant of the aircraft seat to which the PSU control corresponds. The notification ring may be activated by the passenger or by the cabin crew, and may be visible throughout the aircraft. The notification rings may indicate an attendant call, or be activated by the crew in groups or waves to direct passenger activity. The PSU control includes a user interface (UI) display that serves as a control interface for the gasper outlet and reading light. The UI display may also show indicators or messages sent by the cabin crew.

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.

Air distribution nozzles, aircraft that include air distribution nozzles, and methods of utilizing air distribution nozzles are disclosed herein. The air distribution nozzles include an elongate inlet chamber, an elongate outlet chamber, and an elongate slot that extends between, and fluidly interconnects, the elongate inlet chamber and the elongate outlet chamber. The air distribution nozzles also include a suction inlet chamber that extends from a suction inlet port to the elongate inlet chamber. The suction inlet port opens into the suction inlet chamber. The air distribution nozzles further include a motive fluid inlet port that extends into the elongate inlet chamber. The air distribution nozzles also include a sensor port that extends into the suction inlet chamber. The air distribution nozzles further include an elongate outlet port that extends from the elongate outlet chamber.

A position detector for a passenger service unit which can be installed in a passenger service channel. The position detector includes a sensor rail which has a multiplicity of sensors and is configured to be fitted in the longitudinal direction of the passenger service channel. The position detector also includes a position marker which is configured to be fastened to the passenger service unit and to trigger a sensor signal at one of the multiplicity of sensors. A passenger service channel having a position detector and a vehicle area having a passenger service channel are also described.

A Passenger Service Unit (PSU) including an outer plate having an aperture therethrough. The outer plate has symmetry about at least one outer plate axis. The outer plate is configured to be couplable to a passenger compartment at a first position and a second position nonadjacent to the first position. The PSU also includes a first insert configured to be coupled to the outer plate and includes at least one component to be manipulated by a passenger in the passenger compartment. The first insert has symmetry about at least one insert axis and at least a portion of the first inner plate fits within the aperture. Further, the inner plate is rotatable with respect to the outer plate such that the inner plate can be coupled to the outer plate in a first orientation and a second orientation offset by substantially 180 degrees from the first orientation.

A passenger service unit (PSU) for a transport vessel has a unitary chassis with a plurality of apertures extending therethrough. Each one of the apertures is independently sized to receive at least one of a plurality of different modules. Each one of the modules includes one or more PSU fixtures having components different from other ones of the plurality of modules. A representative vessel is a passenger aircraft. Representative modules include vent and passenger reading light module, speaker module, passenger oxygen supply module and display module.
