High efficiency fan blades
WebAxial fans with three kinds of blades are discussed and compared under design and off-design conditions. The present results show that: under design conditions, the total pressure efficiency of the axial flow fan with the forward swept blade is the highest, and the C-type blade has slightly lower efficiency while the straight blade has the lowest efficiency. Web27 de out. de 2024 · Aerofoil fans function just like a series of small airplane wings attached to a hub, with one notable exception. In axial fans, the aerofoil’s twisted design ensures that the incident angle between the aerofoil and the airflow is constant along the blade length, giving a uniform blade loading for high efficiency, low noise fans.
