西德道尼尔公司建造的新型螺旋桨发动机客机将首次装上光纤陀螺仪。这种陀螺仪通过测量光纤回路中光的变化来感测回转情况。记下这种光相对于三个轴中每一轴的变化轨迹,就能确定飞机的航向。道尼尔公司的 DL328型螺旋桨发动机客机,约可乘30名旅客,将于1991年作首次飞行。由于光纤陀螺仪小型和牢固,美国军方也想用这种陀螺仪来导航飞机和制导空间武器。传统机械陀螺既笨重,又易受冲击的影响,起动缓慢,价格很贵。一种替代装置是用环形
For the first time, a new propeller engine passenger plane built by West Deneal will be fitted with a fiber optic gyroscope. This gyroscope senses the slewing condition by measuring the change in light in the fiber loop. Make a note of the trajectory of this light relative to each of the three axes to determine the heading of the aircraft. The Minneapolis DL328 propeller aircraft, which will take about 30 passengers, will make its first flight in 1991. Due to its small size and firmness, the U.S. military also wants to use such gyroscopes to navigate aircraft and spacecraft. Traditional mechanical gyro is bulky, but also vulnerable to the impact of the slow start, the price is expensive. An alternative device is ring-shaped
