The Luna Sensor Suite for Aircraft Corrosion Monitoring (LS2A-802) is a wired or wireless sensor node capable of autonomously monitoring environmental and corrosivity parameters to determine the atmospheric severity of difficult to access regions within airframes. The technology uses both commercial-off-the-shelf and novel sensor elements to monitor a set of parameters and provide an ISO-9223 classification of the environment’s corrosivity. In addition to providing a high-level environmental severity classification, the nodes maintain all raw sensor data with internal storage for future access and engineering analysis. Data from the sensor nodes can be accessed via RS-485 wired or 802.15.4 wireless interfaces. This video highlights the key features and functions of the LS2A system and how it can be used to improve aircraft corrosion maintenance practices.
