Abstract

A support structure for an air supply arrangement for air conditioning aircraft passenger cabins. The air supply arrangement comprises an centrally controlled cabin ventilation system and an individually adjustable cabin ventilation system. The support structure includes: a first section for receiving and/or integrating cabin ventilation system components, a second section for receiving and/or integrating passenger emergency oxygen supply components and a third section comprising a plurality of receiving devices. Each receiving device receives and releasably secures an active module for individually adjustable cabin ventilation. The third section has at least the number of receiving devices required for at least one receiving device to be associated with each seating row for a maximum number of seating rows arrangeable in the cabin A supply system includes at least one such support structure and one of the active modules. A method is provided for configuring a corresponding supply system.

Claims

1. A support structure for use in an air supply arrangement for air conditioning passenger cabins in aircraft, wherein the air supply arrangement comprises at least one centrally controlled cabin ventilation system and an individually adjustable cabin ventilation system, and wherein the support structure comprises:

a first section extending along a longitudinal length of the aircraft and arranged to receive and/or integrate components of the centrally controlled cabin ventilation system and configured to provide a continuous supply of fresh air to the passenger cabin,

a second section separate from the first section extending along the longitudinal length of the aircraft, located adjacent to the first section in a width direction of the aircraft cabin, when used therein, perpendicular to the longitudinal length of the aircraft and arranged to receive or integrate components of an emergency oxygen supply for the passengers, and

a third section separate from the first and second sections extending along the longitudinal length of the aircraft, located adjacent to the first and second sections in the width direction of the aircraft cabin perpendicular to the longitudinal length of the aircraft, comprising a plurality of receiving devices,

wherein each receiving device is designed to receive and releasably secure an active module for individually adjustable cabin ventilation, and

wherein the third section has at least the number of receiving devices required for at least one receiving device to be associated with each seating row for maximum occupancy of the passenger cabin with a maximum number of seating rows arranged at a predetermined minimum spacing.

2. A support structure according to claim 1, wherein the first section comprises an air conduit and an outlet for the cabin ventilation system, which are designed such that they are integrated in the support structure.

3. A support structure according to claim 1, wherein the third section comprises a supply conduit which is connected by at least one connecting opening to each of the plurality of receiving devices of the third section, wherein in particular each receiving device of the third section is of a cylindrical construction and is delimited by a generated cylinder surface and an end face, and wherein in particular the at least one connecting opening is constructed at the end face of the cylindrical receiving device.

4. A support structure according to claim 1, wherein the supply conduit comprises an air conduit and at least one power and/or data conduit.

5. A support structure according to claim 1, wherein at least one sensor is associated with each receiving device, said sensor being designed to establish whether the receiving device is equipped with an active module.

6. A supply system supplying passengers in a passenger space, comprising at least one support structure according to claim 1 and at least one active module for individually adjustable cabin ventilation.

7. A supply system according to claim 6, which comprises at least one further, passive module, wherein the passive module is designed to be received in at least one of the receiving devices of the third section of the support structure in which no active module is received.

8. A supply system according to claim 7, wherein the active module comprises at least one connection piece corresponding to the connecting opening of the third section and at least one air nozzle connected to said connection piece, wherein the active module in particular comprises at least one air quantity control device which is associated with the at least one air nozzle, and wherein in particular the air quantity control device is electrically controllable.

9. A supply system according to claim 7, wherein the passive module comprises a connecting section corresponding to a connecting opening of the supply conduit of the third section and wherein the passive module in particular may comprise operating or comfort elements which are connectable by the connecting opening to a data and/or power conduit of the supply conduit.

10. A method for configuring a supply system according to claim 6 in a passenger cabin of an aircraft, comprising the steps:

determining the configuration of active and passive modules within the support structure with reference to a predetermined occupancy of the passenger cabin with a number of seating rows arranged at a predetermined spacing, wherein at least one active module is associated with each seating row; and

inserting active modules according to the determined equipment of the support structure.

11. A method according to claim 10, comprising the further step:

inserting passive modules into the receiving devices of the third section of the support structure in which an active module is not received.

12. A method according to claim 11, comprising the further step:

determining an equipment for each receiving device of the third section with the aid of sensors, wherein these sensors determine whether a receiving device is equipped with an active module.

13. A method according to claim 12, comprising the further steps:

comparing the determined equipment of the support structure with a predetermined equipment; and

transmitting feedback relating to whether the determined equipment of the support structure corresponds to or deviates from the predetermined equipment.
