摘要
应用旋转天平使飞机模型在风洞里模拟飞机尾旋时的旋转运动 ,并测量出旋转模型上的气动力 ,从而对飞机的尾旋特性进行分析、预测 ,这是研究飞机尾旋特性的有效方法之一。较为详细地介绍了低速风洞旋转天平的工作原理及结构设计。
By way of simulating trial of plane model whirligig in wind tunnel by use of rolling balance and measuring the aerodynamic force on circumvoluting model,we can analyse the trial spinning characteristic.This is one of the efficient way. The paper introduced the working prinnciple and structural design of rolling balance for low speed wind tunnelindetail.
