    Abstract: 有鑑於國外直昇機的研發已臻一定的水準, 而目前研究的熱門課題則在於噪音的問題。其中葉片-渦流(Blade-Vortex Interaction(BVI))噪音之理論預估的技術已經成熟, 而葉片-尾流(Blade-Wake Interaction (BWI))噪音也已積極投入研究。反觀國內尚缺乏直接從事旋翼研究之人才, 此外, 對於渦流及直昇機特有之尾流的區分及影響仍有些許模糊的誤解。因此本文將BVI及BWI噪音之區別及理論研究做一敘述, 並對未來BWI噪音之研究做一評估, 希望能讓大家對於直昇機的尾流之影響有更進一步的認識。
    The noise prediction and/or reduction is the most popular research topic for helicopter rotor problems. The Blade-Vortex Interaction noise (BVI noise) prediction technology is well developed. However, the Blade-Wake Interaction noise (BWI noise) problem is still a challenge for current researchers. The wake configuration for a helicopter main rotor is so complicate that even analytical and/or numerical formulation is hard to establish an accurate model. The BVI and BWI definition is easily confused by researchers who is not doing helicopter analysis. This paper presents a detailed description of both models. Current theories regarding BVI and BWI noise researches have presented. The future studies and research aspects have recommended.
