Guest guest Posted July 3, 2009 Report Share Posted July 3, 2009 Thanks for this story, . http://www.cnn.com/2009/US/07/03/bleed.air.contamination/ index.html One of the links in the story is to a diagram showing where this " bleed air " comes from. From inside the jet engines. http://www.cnn.com/2009/US/07/03/bleed.air.contamination/index ..html#cnnSTCOther1 The good news is they pull it out from the engine before the ignition area so the air should be clean. The not so good news is the air is still subject to lubricants and other liquids necessary in the front end of the turbine. (Consider how air purifier lubricants can sometimes be a problem if the bearings are sleeve bearings instead of sealed bearing... if they don't fail, that is). Just to show how this is another " damned if we do, damned if we don't " situation created by engineering which excludes people from the equation, check out Fairechild's experience in the 1970s at: http://www.flyana.com/ She was a flight attendant on the LA to London flights who got sick. She discovered that the " fresh air " to the cabin was being reduced to save fuel. How was that? There were switches in the cockpit to control how many " air packs " were running. Air packs are what the CNN article describes: " Fresh " air pulled from the jet engines and injected into the passenger cabin. Not enough air pack air caused passengers and flight attendants to get loggy. Too much and they sometimes get higher exposures to oil and other liquids from small leaks inside the jet engine. According to the CNN article the newest jetliners now being built have a different way of getting air into the cabins. Not to solve a problem - of course - (that would be admitting they are liable) but because they found a " better " engineering method. Even when they fix a problem, there is no acknowledgment of the people being helped or harmed. People are invisible.
