Boeing 787: Clean cabin air, June 2007
In evidence to the 2007 UK House of Lords enquiry, Boeing admit that traditional bleed air design is flawed.
“The Boeing 787 will have a no-bleed architecture for the outside air supply to the cabin. This architecture eliminates the risk of engine oil decomposition products from being introduced in the cabin supply air in the rare event of a failed engine compressor seal. In addition, this architecture improves fuel efficiency, thus reducing fuel burn and associated engine emissions.”
