COMPUTATIONAL STUDY ON NOISE GENERATION FROM A TWO-WHEEL MAIN LANDING GEAR
M. Murayama, Y. Yokokawa, K. Yamamoto
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.
