Wind turbine blade (vhiri) chimwe chezvinhu zvakakosha zvemidziyo yemagetsi emhepo, inoverengera inosvika 15% - 20% yemutengo wakazara wemidziyo.Magadzirirwo ayo achakanganisa zvakananga kushanda uye mabhenefiti emidziyo.
Fani mablades anowanzo shandiswa mumafeni, turbine blowers, midzi blowers uye turbine compressors.Iwo akakamurwa muzvikamu zvisere: centrifugal compressors, axial-flow compressors, anodzosera compressor, centrifugal blowers, midzi blowers, centrifugal mafeni, axial-kuyerera mafeni uye imi vanofuridza.
