Multifunctional sting support system at high angle of attack is the main way of support for aircraft test in 8 m×6 m wind tunnel. In recent five years, a series of supporting facility has been developed to improve test efficiency and enhance the finer testing and measuring capability. New developed vibration suppression system can not only enlarge the maximum weight-bearing of the support mechanism, but also reduced the vibratory frequency of a model. Power (motor) control system was modified to adapt to the requirement of 0.2% precision. TG1801 balances were designed and manufactured with high precision and good stiffness. A remote control unit has been applied for a specific aircraft test as model facility to reduce labor intensity and raise test efficiency. Aircraft test efficiency in 8 m×6 m wind tunnel has been increased gradually and data accuracy reaches the advanced international level through these improvements.
