Research on Dynamic Parameter Measurement Technology Dynamic parameter measurement is an important part of modern wind tunnel test technology. It is a key issue that needs to be solved urgently to match the flow field of aircraft intake and engine. The dynamic parameter measurement system applied in wind tunnel has bad operating environment, small signal and high precision. Developed this 20-channel high-precision, reliable, efficient and easy to use dynamic parameter measurement system to solve the long-term domestic unsolved
