摘要
对新型国产DSY128电子扫描压力测量系统及其方框图的各部分组成及功能作了较详细地说明，同时，详述了该系统在西工大低湍流度风洞翼型压力分布实验及沈阳空气动力研究所新建1．2m风洞流场校测中的现场使用情况，给出了几种实验的部分压力分布曲线图。
A new type DSY128 electronic scanning pressure system made in our country is presented in this paper. with the block diagram,analysis and explanation on configuration and function for each part of the pressure system was performed in detail.The pressure system was used for airfoil pressure measurement in low Turbulacne Wind Tununel of NPU,and for flow field calibration in 1.2m Wind Tunnel of institute. Some figures of pressurc distribution show that the DSY128 Pressure system has good effect for practical application.DSY128 pressure system is designed novel and compact. DSY128 pressure not only has high accuracy,stability and reliability,but also can be operated flexibly and conveniently. The main specification and function of DSY128 pressure system has the same level as at the end of 1980s in the world. As the successful development on DSY128 system,it is the first time we can solve the multipoint pressure measurement with high accuracy and high rate and the pressure technology is improved in our country.
