An illuminated aircraft passenger cabin gasper comprises an air outlet for outputting a flow of air into an aircraft passenger cabin and an air guide, movably arranged within the air outlet for adjusting the flow of air that includes a light guide. The gasper also includes at least one light source, arranged adjacent to the light guide for coupling light into the light guide. The light guide has a light output surface for coupling light out of the light guide into the aircraft passenger cabin.

An environmental control system of an aircraft including a compression device including a compressor having a compressor inlet and a compressor outlet, a primary inlet for supplying a first medium to the compressor inlet, and a secondary inlet for supplying a second medium to the compressor inlet.

An aircraft interior structure for an aircraft cabin may include a main body with a plurality of walls, where at least one wall of the plurality of walls may be shared with an adjacent passenger suite including an aircraft seat. The passenger suite may be installed at an angle relative to an aisle of the aircraft cabin. The aircraft interior structure may include a cavity defined within the main body. The cavity may be a trapezoidal shape defined at least in part by the angle at which the passenger suite is installed in the aircraft cabin. The cavity may be configured to receive a plurality of galley carts. A length of each of the plurality of galley carts may be dependent on a depth of the cavity at respective locations in the trapezoidal shape.

An aircraft air conditioning system comprising an ambient air line, for ambient air to flow through, connected to supply ambient air to a mixer of the aircraft air conditioning system. An ambient air compressor is arranged in the ambient air line for compressing the ambient air flowing there through. A refrigerating apparatus comprises a refrigerant circuit for a refrigerant to flow through, including a refrigerant compressor arranged in the refrigerant circuit. The refrigerant circuit is coupled thermally to the ambient air line to transfer heat from the ambient air to the refrigerant before the ambient air is supplied to the mixer. A cabin exhaust air turbine is connected to a cabin exhaust air line, is coupled to the ambient air compressor arranged in the ambient air line, and is configured to expand the cabin exhaust air flowing through the cabin exhaust air line and to drive the ambient air compressor.
