I-wind turbine blade (isondo) ingenye yezingxenye eziyinhloko zempahla yamandla omoya, ibalwa cishe ku-15% - 20% wesamba sezindleko zamathuluzi.Ukwakheka kwayo kuzothinta ngqo ukusebenza kanye nezinzuzo zemishini.
Ama-fan blade ajwayele ukusetshenziswa kumafeni, izifutha zikagesi, izifutha zezimpande kanye nama-compressor omoya.Ahlukaniswe ngezigaba eziyisishiyagalombili: ama-centrifugal compressor, ama-axial-flow compressor, ama-compressor aphindaphindayo, ama-centrifugal blower, ama-root blower, amafeni amaphakathi, amafeni okugeleza kwe-axial kanye nama- blower ye.
