拟开设航空气动声学实验与理论相关课程

航空发动机气动声学和短舱声衬降噪技术，包括高效声衬设计方法、宽频高效声阻抗提取技术、宽频线性低流阻航空声衬与声阻抗建模、声学超材料等。

提出并建立一套高精度、高流速、高频、高效的声衬声阻抗提取实验方法+平台，覆盖航发风扇0.2-10kHz主要频率范围，打破NASA方法3kHz上限，效率提高2-3个量级，且测点数量大幅减少。提出一种针对航空发动机圆/环管、有限长、局域/非局域两大类声衬的高效解析设计方法，揭示了有限长耗散型声衬的降噪机理。发展航空发动机先进多自由度金属丝网宽频、线性、低流阻声衬新构型，研究其高声强效应、掠流效应、宽频特性等并建立声阻抗模型。
