铰链力矩测力试验是主要的风洞试验项目之一,作为测力核心的铰链力矩天平受模型外形限制严重,结构不统一,在高速暂冲式风洞中还面临较大的冲击载荷以及天平温度分布梯度大等问题,实现精确测量难度很大。针对该问题,中国空气动力研究与发展中心高速所依靠其风洞硬件以及人才优势,开展了多个项目的铰链力矩天平攻关,经过多年的研究发展,研制出一系列结构独特的铰链力矩天平,基本满足了各类飞行器的高速风洞铰链力矩试验需求。

The hinge moment dynamometer test was one of the primary wind tunnel test project, and as the dynamometry core, hinge moment balance was restricted severely by model appearance, and its structure was not uniform. There were many difficulties in high speed temporary impact wind tunnel, such as big impact load and large gradient of balance temperature distribution, etc. It was very difficult to realize precision measurement. To solve this problem, High Speed Aerodynamics Institute of China Aerodynamics Research and Development Center(HSAI-CARDC) relied on its wind tunnel hardware and talent advantages to carry out the hinge moment balance research of several projects. A series of hinge moment balance with unique structure had been developed after years of research and development, and basically met the needs of the hinge moment of all types of aircraft in high-speed wind tunnel.
