美国空军正在试验一种能在飞机可能突然失效前察觉其腐蚀情况的检测装置,以保证飞机飞行时的安全。由Battelle研制的该装置是将很小的金属传感元件安装在飞机难以接触到的部件上,然后自动监测这种传感元件的电阻变化,由此可检测出飞机部件腐蚀的开始及加剧。在腐蚀时,随着传感元件横截面积的减小,必然会引起电阻增加。来自各个传感器的所有信号,输送到安装在飞机上的接收系统的中央数据记录器中,相应的腐蚀速度便可由数据记录器计算出来。 Battelle装置的样机已在实验室通过鉴 The U.S. Air Force is testing a test device that detects the corrosion of a plane before it suddenly fails to ensure its safety during flight. The device, developed by Battelle, was designed to mount tiny metal sensing elements on hard-to-reach parts of the aircraft and then automatically monitor changes in the resistance of such sensing elements, thereby detecting the onset and intensification of corrosion of aircraft components. In corrosion, as the sensor cross-sectional area decreases, will inevitably lead to increased resistance. All signals from each sensor are sent to a central data logger mounted on the receiving system of the aircraft and the corresponding rate of corrosion is calculated by the data logger. The Battelle unit’s prototype has been approved by the laboratory
