AF5-R Engine Cooling Fan

Are ring fans quieter than open bladed fans? Well there’s a good question and one that’s not easy to answer. So, where is the noisiest part of a fan, arguably it is the tip of the blade on the trailing edge. Here the flow is turbulent, recirculating and most of the work is done. So does sealing the ends of the blades with a ring help, in short yes it helps prevent some of the recirculation but no it wont make your fan whisper. Please get in touch for more info.
