Determining the 'health' of naval aircraft in terms of corrosion damage is essential for reducing life-cycle costs and increasing the service life. A technology that can monitor the magnitude of corrosive conditions an aircraft system is exposed to has been developed. The approach involves use of thin film galvanic sensors to measure the corrosive nature of localized environment in real time. The data is continuously monitored and stored in a device called Corrosion Monitoring System (CMS) which has a removable memory card and a microprocessor or controller. The output of this sensor has shown excellent correlation with the laboratrory-generated data in terms of corrosive nature of the environment and the magnitude of the current developed. Typically, these sensors are attached like postage stamps at various places such as under coatings, inside lap-joints, composite lay-ups and hidden locations of aircraft structures and avionic boxes. They are able to sense even benign corrosive (in less than 60 % R.H.) atmospheric environments. Currently these sensors are being field tested on several operational aircraft (H-65s, H-53s and P-3) and stored or preserved aircraft systems (F-4s, AV-8s). Monitoring corrosivity on operational aircraft provides an understanding on the extent of damage an environment would produce on aircraft components during deployment. It will also help develop a cue as an early warning sensor and determine if there is any need for maintenance/repair action.
