BLEED AIR explained

A simple video explanation of the bleed air system used on almost all aircraft, except the Boeing 787 Dreamliner and which may cause problems with contaminated air. From the documentary feature film: "UNFILTERED BREATHED IN - The Truth about Aerotoxic Syndrome", Germany 2015 by Tim van Beveren

Bleed Air is a variety of sources and destination for air that leaves the compressor upstream of the nominal compressor outlet.Bleed air system can be used for internal cooling of the engine, cross-starting another engine, engine and air frame anti-icing, cabin pressurisation, pneumatic actuators, air-driven motors, pressurising the hydraulic reservoir etc...

Never heard of this must be really rare that the oil seals leak oil into the compressor.

[@tvbmedia]

the seals do actually leak constantly as "by design". Minimal amounts, but this is measurable and has been measured. See the PhD thesis of Caspar Faltland Solbu from Norway who conducted measurements on behalf of a Norwegian government institution back in 2011 and 2012...

bleed air comes out from the the compressed air and not from the turbines

[@tvbmedia]

+Extreem Peace Yes, exactly. So what? Bleedair becomes "bled off the compressor stages within the turbine". What's your point?

[@extreempeace147]

oops sorry, I guess this is something new for me to learn. Thanks again
