The mode of aquisition is complied by C and assembly to increase acquisition speed. 本文介绍的全台压气机试验器性能曲线实时跟踪系统,是根据排气节气门的变化,进行动态跟踪处理及显示的监控系统。本系统的软件是用QB4·5快速BASIC和汇编两种语言混合编制的,解决了在西文DOS下使用国际GB-2312汉字库显示汉字、实时汉字下拉菜单选择、动画跟踪、鼠标器操作修改设计曲线等技术问题。 An experimental investigation on the effect of the rotor wake on unsteady loading of downstream stator has been carried out in a low speed single stage axial compressor.The unsteady pressure distribution along the stator blade was measured,and the effects of axial gap between rotor and stator,operating rotation speed and mass flow of the compressor were investigated in detail.The experimental results show that all these factors have a great effect on the rotor-stator interaction.The incidence change caused by... An experimental investigation on the effect of the rotor wake on unsteady loading of downstream stator has been carried out in a low speed single stage axial compressor.The unsteady pressure distribution along the stator blade was measured,and the effects of axial gap between rotor and stator,operating rotation speed and mass flow of the compressor were investigated in detail.The experimental results show that all these factors have a great effect on the rotor-stator interaction.The incidence change caused by the velocity defect in the rotor wake has a major impact on the unsteady pressure distribution and lift of the stator blade.The amplitude of the pressure fluctuation reaches maximum at the blade leading edge and decays rapidly towards the trailing edge on the pressure side.The interaction intensifies with the decrease in the mass flow or the increase in the rotation speed.The results of the investigation on the influence of axial gap between rotor and stator ( ) show that,the unsteady pressure distribution and the lift of the stator blade fluctuate strongly as <0 4,and the fluctuation intensity decreases quickly as increasses. 本文利用南京航空航天大学单级低速轴流压气机试验器，对动叶尾迹对静子非定常气动性能的影响开展了系统的实验研究。通过静叶表面动态压力分布的测量，获得了在不同的动—静叶排轴向间距、不同的工作转速和不同的工作流量下，动叶尾迹对静子非定常气动性能影响的大量基础实验数据
