高、低能扰动力函数对叶轮机阵发非定常气动力的影响(英文)

为了研究扰动力函数对多级叶轮机叶片排中基本的高、低能阵发非定常气动响应的影响,在研究用轴流压气机上进行了一系列的基础研究。 

2-E FORCING FUNCTION EFFECTS ON TURBOMACHINE GUST UNSTEADY AERODYNAMICS

To investigate the forcing function effects on the fundamental 2 E gust unsteady aerodynamic response of a multistage turbomachine blade row,a series of fundamental experiments are performed in an axial flow research compressor.The 2 E unsteady aerodynamic forcing function excitations are generated by both a circumferential inlet flow distortion and the wakes from airfoil type obstructions which are representative of an airfoil,strut,or probe excitation.
