Electric Control System of the Rotary Test Set

The rotary test set in φ5m vertical wind tunnel is a kind of important basic equipment which is designed and established for research of airplane spin characteristic.It is mainly used for observing aerodynamic characteristics while the test model spins around wind flow with different velocities,and providing the necessary aerodynamics parameters to analyse and predict the spin characteristic.It is used for the rotary balance test,dynamic derivatives test,large incidence test and coupled rotary vibration test.The control system of set is mostly built up Siemens automation and drive production.The configuration,the composing of control system,function,the key technique had been settled were introduced,the coupling control of more free setup and more exactitude motion control have been realized,every technique index is adapt to desiring of the test.
