干式调谐陀螺不仅可以用一个陀螺构成两个输入输出系统,而且与一般液浮积分陀螺不同,由于不需要浮油,所以温度控制精度要求比较低,还有不需要软导线供电等优点。因此美国在80年代初就考虑将其作为捷联惯性基准装置的陀螺,在体积、重量、耗电量、精度及可靠性等方面作了一些改进研究,逐渐进入实用阶段。特别是采用三个干式调谐陀螺作为冗余系统,研制了DRIRU-Ⅰ(冗余惯性基准装置开发-Ⅰ)和DRIRU-Ⅱ(干式转子惯性基准装置-Ⅱ),并最先用于多用途地球探测卫星(Landsat)和ETS-Ⅲ等。在1977年8月发射的探测卫星“旅行者”的姿态控制用的惯性基准装置中也采用了三个干式调谐陀螺。在日本,从1977年开始,由航空宇宙技术研究所和宇宙开发事业团合作研制干式调谐陀螺,对关键性部件挠性接头进行了设计分析和试制。该干式调谐陀螺的第一次试制工作已经完
The dry tuned gyroscope can not only use one gyro to form two input and output systems, but also differs from other liquid floated integral gyroscopes in that it does not require oil slick, so the temperature control accuracy is relatively low, and there is no need for soft-wire power supply. Therefore, in the early 1980s, the United States considered its use as a gyroscope for a strapdown inertial reference device and made some improvements in terms of volume, weight, power consumption, accuracy and reliability, and gradually entered the practical stage. In particular, the DRIRU-I (Redundant Inertial Reference Unit Development-I) and DRIRU-II (Dry Rotor Inertial Reference Unit-II) are developed using three dry tuned gyros as redundant systems and were first used in many Use Earth exploration satellite (Landsat) and ETS-Ⅲ and so on. Three dry tuned gyroscopes were also used in the inertial reference device for attitude control of the probe satellite “traveler” launched in August 1977. In Japan, dry-tuned gyroscopes were jointly developed by the Institute of Aerospace Technology and the Cosmos Development Group since 1977, and the design and analysis of the flexible joints of key components were conducted. The first trial of the dry tuned gyro finished
