Flow in the inter-wheel region of landing gear systems

起落架系统设计、开发和制造领域的世界领先企业梅西埃-布加迪-道蒂公司与多伦多大学的Alis Ekmekci教授正在启动一项研究合作伙伴关系，以调查起落架轮之间区域的气流及其与噪声产生的关系。飞机产生的噪音使许多居住在机场和大型飞行走廊附近的人感到沮丧。由于公众对这一问题的强烈反应，多年来噪音政策变得越来越严格，使航空业面临制定噪音缓解战略的压力。由于起落架系统在飞机上的海崖性和位置，起落架系统特别地被识别为在飞行的进近和着陆阶段期间的大的噪声源。起落架产生的噪声是起落架周围脉动流及其与飞机部件表面相互作用的直接结果。然而，在这些系统中的噪声产生的基本机制仍然没有很好地理解。

Messier-Bugatti-Dowty, a world leader in the design, development and manufacture of landing gear systems, and Prof. Alis Ekmekci from University of Toronto are initiating a research partnership to investigate the flow in the region between landing-gear wheels and its connection to noise generation. Noise generated by aircraft blights many who live close to both airports and large flight corridors. As a result of the strong public response to this issue, noise policies became increasingly stringent over the years, putting the aviation industry under pressure to develop strategies to mitigate noise. Due to their bluff nature and position on the aircraft, landing gear systems in particular are identified as a large source of noise during the approach and landing phase of a flight. Noise generated by landing gear is a direct result of the fluctuating flow developing around landing gear and its interactions with the surfaces of the aircraft components. Nevertheless, the basic mechanisms of noise generation in these systems are still not well understood.
