中文摘要

飞机起落架是大型钝体附件，会产生高度复杂和不稳定的流动，表现为噪音。飞机噪音不仅对居住在机场附近的人造成严重干扰，而且还与对人们健康的负面影响有关。为了限制噪音排放，航空当局制定了严格的规定，向航空公司征收与噪音相关的费用，为飞机运营商提供了财政激励，以尝试减少他们的噪音排放。因此，了解噪音产生的来源并尽可能减少噪音，符合许多不同方面的利益。
英文摘要
Aircraft landing gears are large, bluff bodied appendages that create highly complex and unsteady flow, manifesting itself as noise. Aircraft noise not only causes significant disturbance to those that live near airports, it has also been associated with negative impacts on people's health. In an effort to restrict noise emissions, aviation authorities placed stringent regulations that impose noise related fees on airlines, providing a financial incentive for aircraft operators to try and reduce their noise emission. It is therefore in the interest of many diverse parties to understand the sources of noise generation and mitigate them wherever possible.
