The two electrodes of each pair of electrodes are spaced apart from each other along a longitudinal direction (A) of the respective discharge light module. The pairs of electrodes include at least one first pair of electrodes assigned to the at least one first discharge light module, and at least one second pair of electrodes assigned to the at least one second discharge light module.

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.

A gas turbine engine is disclosed having a tip clearance control system. The tip clearance control system has a cabin blower system, a casing arranged in use about a rotor of a gas turbine engine and a fluid delivery passage. The cabin blower system having a cabin blower compressor arranged in use to compress fluid used in a cabin of an aircraft and to compress fluid conducted via the fluid delivery passage into heat exchange with the casing.

An air supply system for passengers includes an air supply line with a plurality of laterally situated air outlets, an individual air panel with at least one air nozzle and an air inlet opening. The individual air panel can be variably positioned along the air supply line in such a way that the air inlet opening faces one of the air outlets. A plurality of magnetic valves is arranged at the air outlets of the air supply line. One of the magnetic valves may be magnetically actuated by the individual air panel, when the air inlet opening of the individual air panel faces said one magnetic valve, so that air can flow out of the air supply line through the air outlet and the air inlet opening to the air nozzle.

A passenger supply system installed in a passenger supply channel (PSC) on board a vehicle, such as an aircraft. The supply system comprises a rail track configured to be mounted along the PSC. The supply system further comprises an indiv panel mounted on the rail track and connectable to the PSC for supplying a passenger with conditioned air, medical outlet and/or oxygen. The indiv panel comprises a crossover area. The supply system further comprises a passenger supply unit mounted on the rail track and connectable to the PSC for supplying the passenger with light, visual information and/or sound information. The supply unit comprises an overlapping area. The supply unit and the indiv panel are configured such that in a mounted state of the supply unit and of the indiv panel the overlapping area of the supply unit at least partially overlaps with the crossover area of the indiv panel.

The invention relates to an overhead luggage compartment for aircraft, comprising: a tray for accommodating pieces of luggage, which tray can be pivoted about an axis of rotation between a closed position and an open position; and comprising a housing, which encloses the tray in the closed position and which has devices arranged thereon for fastening to a supporting structure of the aircraft and has a suspension device for a passenger service unit; and comprising a closure element for holding the tray in the closed position. The housing is formed by two frame parts arranged lateral to the tray, which frame parts are connected to each other by means of cross-braces, and the fastening devices and the suspension device for the passenger service unit and at least one stop element for limiting the open position of the tray are arranged on the frame parts.

In an illustrative embodiment, an apparatus for treating air discharged to a passenger suite of an aircraft includes an enclosure that houses components for treating air passing through the enclosure and a detachable cover connected to the enclosure that provides access to the components. Air treatment components associated with air treatment flow paths within the enclosure include a blower with a fan that draws air through an air intake on the enclosure. An air duct is affixed to a discharge of the blower and directs the air discharged from the blower through an air treatment flow path that includes a scented cartridge with a scented medium that is absorbed into the air passing through the air duct. An air exhaust port is attached at a discharge end of the air duct that discharges the air conditioned by the scented cartridge through an air exhaust vent on the enclosure.

A gasper for use in a passenger aircraft includes an inlet configured to receive air. The gasper further includes an outlet configured to output the air towards a passenger seat. The gasper further includes a body extending from the inlet to the outlet and being adjustable between at least three lengths.

A passenger service unit assembly that includes a frame that defines at least an oxygen opening and a service opening, an oxygen mask housing positioned adjacent the oxygen opening, an oxygen mask housing cover positioned to cover the oxygen opening, and a service cover positioned to cover the service opening. An oxygen mask that is movable between a stowed position and a deployed position is positioned in the oxygen mask housing. The oxygen mask housing cover maintains the oxygen mask in the stowed position. The oxygen mask housing cover is movable between a closed position and an open position. When the oxygen mask housing cover is moved to the deployed position, the oxygen mask drops to the deployed position via gravity. The service cover is movable between a closed position and an open position and includes at least a first passenger service unit component associated therewith.
