The following article presents “Corrosion Prognostic Health Management" (CPHM) System used on helicopter Mi-24. Polish army spends millions of dollars annually on inspection, identification and repair of damage resulting from aircraft corrosion. That is why it is so important to reduce maintenance time and costs. CPHM System helps in this process by reduce maintenance costs and helps in improving the CPCP program. In order to increase aircraft safety, availability, and operational efficiency, Polish army use an on-platform monitoring system.
Corrosion prediction requires inputs, models, and actionable outputs that can be used by maintainers. Aircraft corrosion monitoring systems quantify: Environmental parameters (environmental severity) and Corrosion rate of surrogate materials (corrosivity). Conversion equations from signals from sensors to the rate of loss of current to mass are also very important part of the system.
The article shows the approach to Corrosion Prognostic Health Management (CPHM) System. Explains which sensors have been installed on the Mi-24 helicopter. The authors explain which sensors are selected and why. In what locations were installed on the Mi-24 helicopter (Wireless corrosion monitoring for evaluation of aircraft structural health). Will also be shown data obtained from the operation on the Mi-24 helicopter. The authors will also show correlation between data obtained from corrosion sensors located on the Mi-24 helicopter and data obtained from Atmospheric Corrosion Test Site. It is a necessary process for the correct assessment of the corrosivity of the atmosphere, which will allow for the development of an appropriate corrosivity model in the future.
