Hinge moment balance technique with axial force measurement and its application in wind tunnel test
摘要
Abstract
For resolve the non-axial force measurement limitations of three-component hinge moment balance on wind tunnel control flap test, a operable design plan of four-component hinge moment balance is put forward in this paper, then a physical prototype was application in the elevator experiment. The result shows that the experiment result and theoretical analysis have good consistency when elevator angle is 21 degree, normal force coefficient relative error is 14.7％ and control flap's pressure center position relative error is 20 ％, which ignore the axial force measurement.关键词
