They were able to recognize distinct sound sources originating from the duct, the turning fan, and the air flowing over the curved airframe surface.They found that the sound pattern changes depending on how much thrust the fan is producing. When the fan is producing high thrust, they observed a sound pattern similar to what is seen in fans without ducts. Ahmed stated: “But, there is a catch for embedded ducted fans– how loud or peaceful they are is still a mystery, particularly when they are consuming airflow from around the curved airframe surface.Electric ducted fan mounted next to the curved surface.”Our research study sheds light on how sound is created by futuristic ingrained ducted fans mounted on curved airframe surface areas, revealing that noise patterns vary with fan thrust levels, providing essential insights for quieter next-generation airplane style.
