International landing gear research model LAGOON and four-wheel landing gear model independently designed in China are taken as aerodynamic noise research subjects. Fully transient aerodynamic simulation software Aries calculates PSD change around landing gear model and OASPL directivity in far flow field based on Lattice Boltzmann LES-Smargorinsky model.
