民用飞机风扇的计算气动弹性综述（英文）

The aim of this paper is to present the state-of-the art in computational aeroelasticity methods that are available for analyzing fan blades on modern civil aircraft. Fan blades in modern high-bypass aero-engines typically produce around 80% of the thrust. In order to improve specific fuel consumption and reduce the level of noise emitted from the engine, civil turbofan engine designs are moving toward even larger fan diameters with lower tip speeds and hence the importance of this component of aero-engine becomes even more prominent. To reduce weight, future fan blades will be made of composite materials and shorter intakes are used. The new designs are highly loaded and will be more susceptible to aerodynamic and aeroelastic instabilities, and hence computationally efficient aeroelastic modelling tools for such blades are paramount.

多级压气机气动弹性不稳定性计算方法综述（英文）

本文介绍了现代民用航空发动机多级堆芯压缩机气动和气动弹性不稳定性分析的最新计算方法。现代燃气轮机设计继续朝着提高性能、减轻质量、降低成本的方向发展。由于涡轮机叶片翼型变薄,以改善性能和减轻质量,气动弹性挑战,如颤振和强制响应变得更占主导地位。此外,使用具有非常低的机械阻尼的叶盘(叶片集成盘)在现代压缩机设计中更为常见,在多排环境中准确预测压缩机稳定性变得至关重要。
