Aim\ For the requirement of pneumatic characteristic testing of modern battleplane
the Institute of Fluid Mechanics of BUAA developed the 1.2 m×1.0 m multipurpose water tunnel with modern control theory and measurement technology. Methods\ The design of the measurement and control system of multipurpose water tunnel is introduced in this paper
including system structure and technical features. Results and Conclusions\ Some methods of the real time control and data acquisition during dynamic test are discussed. The operation results show that the target of design is successfully reached.
