Abstract
This paper describes systems commonly employed to deliver aircraft
cabin air, and the internal air system which is responsible for the
supply of balancing, sealing and cooling air used with the engine to
control the operation of bearings, discs and other critical components,
as well as bleed air. A series of mechanisms that could be responsible
for contamination of bleed and cabin air are considered including:
ingestion into the compressor intake of poor quality air; leakage from
a seal of oil; ingestion from the gases associated with a stall or surge
event; off-gassing of cabin fittings and emissions from occupants.
