Study on the method of test and control system for low speed wind tunnel

摘要

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.
