内容摘要Abstract：

Abstract:Aircraft noise remains a significant environmental concern for communities near airports. Dominant noise sources shift with flight phase — engine noise is the primary contributor during take-off. This talk focuses on propulsion noise in propeller-driven configurations, with particular attention to Contra-Rotating Open Rotor (CROR) systems. These tandem counter-rotating propellers pose distinct acoustic challenges: high tip Mach numbers and the absence of a nacelle give rise to intense noise radiation. The talk presents investigations into front-rotor trailing-edge blowing as a noise reduction strategy targeting rotor–rotor interaction noise, i.e., a dominant component of the open rotor acoustic signature during take-off.

飞机噪声始终是机场周边社区面临的重要环境问题。飞机主要噪声源会随飞行阶段发生变化：起飞阶段，发动机噪声是最主要的噪声来源。本次报告聚焦螺旋桨飞行器的动力装置噪声，重点研究对转式开放式转子（CROR）系统。

这类前后串联的对转螺旋桨存在独特的声学难题：桨叶尖端马赫数高，且无整流罩包裹，会产生强烈的噪声辐射。报告将研究前转子后缘吹气这一降噪技术，该方法主要针对转子间干涉噪声—— 也就是开放式转子起飞阶段最核心的噪声源，以此实现降噪优化。
