本文概括地介绍目前在高速风洞中测定飞行器铰链力矩所采用的几种半模型实验方案,着重叙述一种简易的实验装置及其测力器——扭力天平的设计,最后并介绍用这种装置所获得的初步经验和存在问题。值得提出的一点是述及的扭力天平设计原理也可应用于尾杆式电动多分力天平滚转元件的设计和动力学力测量中。
This paper presents a brief introduction of several semi-model experimental schemes used in the determination of aircraft hinge moment in high-speed wind tunnel, and focuses on the design of a simple experimental device and dynamometer-torsion balance. Finally, Initial experience and problems with the device. It is worth mentioning that the principle of torsion balance can be applied to the design and dynamic force measurement of the tail rotor electric multi-component balance roller.
