| Abstract: | This paper intreduced that turbine of the type 500mm fan dischmpe of low noise aerodynamicwas used an aiffoil of large stall angle of attack and high lili and an airfoil was designed using the modifiedStheifonl's optimum pressure distribution. The exPerimental results showed that the discharge of the new turbineincreased four percent than old and the noise of the new turbine decuned 15 dB than old. |
