The Study of Measurement Techniques of Microscale Roll Moment Balance for Dynamic Test

According to special requirements of microscale roll moment measurement of a tactical missile model in wind tunnel for the dynamic aerodynamic characteristics, the research on the microscale roll moment measurement technique of the wind tunnel experience on the dynamic aerodynamic characteristics was conducted. A high-precision wind tunnel balance of the microscale roll damping moment has been developed successfully, and the static calibration of the wind tunnel balance, wind tunnel experiment and performance evaluation were was completed. The results of the experiment indicate that the sensitivity of balance is reasonable, anti-jamming ability is strong and the precision of the experiment is high, so the balance can satisfy the requirements for microscale roll moment measurement of a tactical missile model in wind tunnel on the dynamic aerodynamic characteristics.
