Aircraft operators being faced with water accumulation in fuel tanks on a daily basis andare looking for reliable detection systems to determine the remaining amount of accumulated iceduring maintenance after flight. Using such a technology, an increase in the safety and efficiencyof the aircraft operation would be possible in this highly competitive market. This article presentsthe use of the Acoustic Emission Technique (AE) for the reliable and non-invasive monitoring of themelting of ice in

This technology is in principle based on the fact that a phase transitioncomes frequently along with stress relaxation that can be used for monitoring the process. Therefore,the melting of water can, in essence, be monitored with AE without accessing the ice directly.The analysis of the AE signals has been carried out in the time domain since it was the melting of iceneeded to be monitored as a function of temperature rise time. The insights presented in this papercan possibly lead to new technologies for ice detection, especially in remote areas that are not easilyaccessible with other techniques.
