Low-speed wind tunnel testing control systems research

The wind tunnel test control is the key to the wind tunnel tests. This article Studied 0.75m × 0.75m With backflow wind tunnel measurement and control technology, through the transformation of the wind tunnel motor to improve the stability and uniformity of the airflow and reduce turbulence degree; through transform angle institutions, increase the angle of attack, sideslip angle and roll angle finesse; through the study of data acquisition and control system, to ensure the fidelity of the data. Effectively improve the scientific nature of the wind tunnel. Keywords-wind tunnel;wind tunnel test and measurement ; control bus structure
