Abstract: The landing gear is a crucial source of the civil airplane noise at take-off and landing, and has been a serious issue for the research field of aerodynamic noise control. After almost half a century study, so far plenty of progress in the field of landing gear noise production reasons and control approaches have been achieved. This paper, to begin with, conducted a quick review of the landing gear noise research history, and made a brief explanation to the noise generation mechanism. Then, the state of art of the landing gear noise reduction technologies at home and abroad was introduced. The corresponding studies were based on different methods including wind tunnel test, flight test, and numerical simulation. The technologies involve faring, pin hole cover, component optimization and air curtain. At last, the research inspiration from home and abroad were discussed, followed by the analysis of current issues. As a consequence, the expectations to the future study on the landing gear noise were made.

Key words: landing gear noise, noise control technologies, fairing, air curtain, large-scale aeroacoustic wind tunnel, flight test
