| Abstract: | A three-component piezoelectric balance for hinge-mo-ment measurements in an impulsive hypersonic wind tunnel is re-ported here.The balance is inertiacompensated and free from flexurestructures.Measurements were carried out in the JF-4B gun tunnel inthe Institute of Mechanics,Chinese Academy of Sciences.Static cal-ibration accuracy and experimental data are presented in this paper.Ithas been proved that the mechanical Structure,the sensitivity,and theinertia-compensation system all meet the design requirements and thebalance works well in measurements of aerodynamical characteristicsof controlling wings on a maneuvering-warhead model. |
