Keywords: aeroacoustics, airframe noise, landing gear

In this paper, obtained knowledge and findings about the flow structures and possible noise sources around a two-wheel landing gear model by a series of steady and unsteady computations are discussed. The flowfields with several low noise devices are also investigated to clarify the noise reduction mechanism.
