Contamination of Bleed Air
Hello, I talked to a maintanance engineer the other day who told ma about a new method of cleaning the inside of an jet engine and thereby augmenting its performance.Itīs basically achieved by water injected under high pressure.The water leaving the compressor stage of the engine is supposed to be that contaminated by traces of heavy metals like nickel,cobalt and chrome that the washings cannot be disposed into the regular sewage water and have to be handled like hazardous waste.
Of course there are more sources for bleed air contamination further downstream as well.
Has anyone ever heard about, or made the experience of physical reactions caused by respirating bleed air through the air conditioning system ?
Is that an issue already discussed earlier ?
Best regards, RvB.
