| Abstract: | An on-line data acquisition, control and processing system, which is centralized by computer, for flow field in NamingAeronautical Institute NH-2 low-speed wind tunnel is described inthis paper. The paper introduces the constitution and character of thesystem. A diagram of system configuration is shown. Every subsystemis introduced briefly. The software design and data processing areemphasized in this paper, and several examples are given. The systemsupplies a powerful means for flow field measurement in low speedwind tunnel. |
