开发一种新的微小速度传感器,以测量穿透过程中高速冲击器的瞬时速度。该装置的原理基于磁铁穿过线圈产生感应电流。设计专用数字电路,消除信号重叠,使空间分辨率优于0.05英寸(0.27mm)。利用信号的精密时间延迟测量高速火箭的减速或能量损耗。描述传感
Develop a new tiny speed sensor to measure the instantaneous speed of a high speed impactor during penetration. The principle of the device is based on the induction current generated by the magnet passing through the coil. Dedicated digital circuits are designed to eliminate signal overlap, giving spatial resolution better than 0.05 in. (0.27 mm). Measure the slowdown or energy loss of a high-speed rocket using the precise time delay of the signal. Describe the sensor
