Abstract:In order to improve synchronization and precision wind tunnel data acquisition, for transonic and supersonic wind tunnel characteristics, design of a transonic and supersonic wind tunnel measurement system. The overall design of the wind tunnel measurement system is introduced, and the new technology and new method of continuous synchronous acquisition with ladder, reflective memory, NI-PSP technical protocol and so on are described in detail. Give the first a standard mold test results. Test results show that: the system is stable and reliable, with data acquisition accuracy, high frequency acquisition, data integrity preservation, high reliability data communication, transmission delay is short and so on, with a high degree of automation and the ability to expand and facilitates domestic self-development.
