Ventilation system for wide-bodied aircraft

A ventilation system for a wide-bodied aircraft with a pressurization cabin, the ventilation system comprising:

• a compressor apparatus with a heat exchanger for drawing air in from an input reservoir and for generating an excess pressure in at least one output reservoir,
• several air outlets in the pressurization cabin which are connected to the at least one output reservoir of the compressor apparatus,
• at least one suction air intake pipe in the pressurization cabin,
• a static volume flow control member for adjusting a volume flow through at least one of the air outlets,
• wherein the static volume flow control member comprises:
• an admission orifice plate with a predetermined internal cross-section in one pipe section,
• an electronic memory coupled to the admission orifice plate for storing orifice plate parameters, the orifice plate parameters are indicative of the non-changeable internal cross-section of the orifice plate for the air flowing through it, and
• a transmission device coupled to the admission orifice plate for transmitting the orifice plate parameters from the electronic memory to an external receiver device, wherein the electronic memory and the transmission device are integrated in an RFID circuit.

A method for manufacturing a ventilation system for a wide-bodied aircraft with a pressurization cabin, the method comprising:

• installing a compressor apparatus with a heat exchanger for drawing air in from an input reservoir and for generating an excess pressure in at least one output reservoir,
• installing several air outlets in the pressurization cabin which are connected to the at least one output reservoir of the compressor apparatus,
• installing at least one suction air intake pipe in the pressurization cabin,
• installing a static volume flow control member before at least one of the air outlets for adjusting the volume flow through the at least one air outlet,
• fitting the static volume flow control member with an orifice plate having a predetermined internal cross section in one pipe section,
• mounting an electronic memory for storing orifice plate parameters on the orifice plate, the orifice plate parameters are indicative of the non-changeable internal cross-section of the orifice plate for the air flowing through it, and
• mounting a transmission device on the orifice plate for transmitting the plate parameters from the electronic memory to an external receiver device, wherein when the plate parameters are read by a mobile reading device, an automatic assignment of an installation site and type of plate takes place.
