Abstract This study investigates the aerodynamic and aeroacoustic behavior of propellers operating in ground-effect conditions. with an emphasis on the impact of porous ground surface treatments. The investigation explores the potential of porous materials to reduce propeller noise near the ground. a major barrier to the acceptance and integration of Urban Air Mobility (UAM) systems. https://smokeysmountainfurnitureoutlets.shop/product-category/bedroom-set/
