在四十年代初,液浮单自由度陀螺是用于火力控制系统角速率测量的简单器件。从四十年代后期开始,由于自主惯性制导的需要,加速了液浮单自由度陀螺的发展。这使得陀螺在元件工艺和结构材料方面有了长足的进步,性能改善了,重量和体积减少了,耐环境的能力增强了。早期陀螺主要用铝合金构成。为得到良好的性能,用铍代替了不大稳定的铝合金。 In the early 1940s, the liquid-floating single-degree-of-freedom gyroscope was a simple device for the angular rate measurement of fire control systems. Since the late 1940s, due to the need of autonomous inertial guidance, the development of liquid single-degree-of-freedom gyroscopes has been accelerated. This makes the gyro in the component technology and structural materials has made considerable progress, improved performance, weight and size reduction, increased environmental resistance. Early gyroscope is mainly composed of aluminum. In order to get good performance, with beryllium instead of not stable aluminum alloy.
