| Abstract: | 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. |
