Aerofoil noise as self-noise is detrimental to system performance. in this paper NACA 0012 optimization parameters are presented for reduction in noise. Designing an aerofoil with little noise is a fundamental objective of designing an aircraft that physically and functionally meets the requirements. Aerofoil self-noise is the noise created by aerofoils interacting with their boundary... https://www.tukangkacafilm.com/product-category/jackets-outerwear/
