This paper evaluates the potential of applying leading-edge tubercles to propellers to be used in advanced air mobility vehicles in order to reduce their noise emission. The geometry is parameterized and multiple designs are assessed aerodynamically and acoustically via simulations. The influence of each parameter and the effectiveness of such modifications to reduce propeller noise are discussed.
