7ompressor Intro •

•

 The 'o#pressor is #a$e p of the fan an$ alternating stages of rotating bla$es an$ stati' vanes. The 'o#pression syste# of a Trent engine 'o#prises the fan, eight inter#e$iate pressre stages an$ six high pressre stages.  The pri#ary prpose of the 'o#pressor is to in'rease the pressre of the air throgh the gas trbine 'ore. "t then $elivers this 'o#presse$ air to the 'o#bstion syste#.  The pressre rise is 'reate$ as air ows throgh the stages of rotating bla$es an$ stati' vanes. The bla$es a''elerate the air in'reasing its $yna#i' pressre, an$ then the vanes $e'elerate the air transferring kineti' energy into stati' pressre rises
