title = "Aeroacoustic Noise Prediction of Rotating Wings in Hover by CFD Method",
abstract = "This paper applies CFD/FW-H method to validate the aeroacoustic noise results of UH-1H model and three rotors with different tip shapes in hover. The numerical simulation applies sliding grid with IDDES turbulence model to predict pressure pulsation causing by the rotating of blades. Sound pressure spectrum and sound pressure level were obtained and validated with experimental results. Results are primarily anastomotic for pressure fluctuation and frequency spectrum with SPL absolute error in range -3.45~7.61 dB. It is found that rotor designed with swept and anhedral tip helps to increase the hovering efficiency and reduce noise to a certain extent.",
