| Noise pollution is a rising concern due to the development of Urban Air Mobility. Researchers at Purdue University have developed a microtextured coating for urban air mobility vehicles to reduce noise pollution for air vehicles at low altitudes. By coating propellers and rotors with this microtextured coating, air has a smoother flow over the blades, which reduces noise pollution. With this innovation the feasibility of future urban air mobility vehicles is increased. Advantages: -Lower noise pollution of 2-4 decibels -Increased feasibility of Urban Air Mobility -Large Scale Fabrication Applications: -Urban Air Mobility vehicles -Aircraft noise reduction -Wind turbine noise reduction -Drag reduction Technology Validation: This technology has been validated in lab testing with cylinders coated with and without micro-structures to show the difference in sound levels up to a 2-4 decibel reduction at high speeds. |
