A Note on Axial Flow Fans for Aircraft Ventilation

A Note on Axial Flow Fans for Aircraft Ventilation AXIAL flow fans were originally developed from aircraft airscrews and therefore can be claimed as children of aeronautical science. Their use has been confined in aeronautics to wind tunnels and radial engine cooling until the advent of pressurized cabins. In this case ventilation requirements have caused an axial flow fan to be used. These fans have been gradually developed in the ventilation industry and they are replacing centrifugal fans where these would have been used previously. Price and noise level have not been in the axial flow fans' favour in this fight but they have advantages of higher efficiency, ease of installation and nonoverloading power characteristic. Latest developments in aerodynamic design and production technique suggest that the disadvantages are being overcome. This note is intended to furnish a general introduction to the design features of axial flow fans for aircraft ventilation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

AXIAL flow fans were originally developed from aircraft airscrews and therefore can be claimed as children of aeronautical science. Their use has been confined in aeronautics to wind tunnels and radial engine cooling until the advent of pressurized cabins. In this case ventilation requirements have caused an axial flow fan to be used. These fans have been gradually developed in the ventilation industry and they are replacing centrifugal fans where these would have been used previously. Price and noise level have not been in the axial flow fans' favour in this fight but they have advantages of higher efficiency, ease of installation and nonoverloading power characteristic. Latest developments in aerodynamic design and production technique suggest that the disadvantages are being overcome. This note is intended to furnish a general introduction to the design features of axial flow fans for aircraft ventilation.
