The low speed wind tunnel was designed and manufactured in NUAA. This paper introduces a data acquisition and processing system of the low speed wind tunnel which is devloped by the author. The system which consists of an advanced electric scanning pressure measurement instrument, a high precision data acquisition part and a channel amplifer, is controlled by a high performance computer with the practical and convenient software. Force and pressure can be measured at the same time giving on-line pressure correction and analogue channel standard signal correction. The design of this system includes many advanced instrumentation concepts,such as electric scanning pressure measurement,analogue signal condition etc. The system has many features, such as high speed data acquisition, high stability, on-line data processing, for providing experimental data report and graphic,convenience for using and repairing.
