Corrosion of aircraft and rotorcraft costs the DoD billions of dollars annually and is the largest maintenance cost driver for the Navy and Marine Corps. Localized corrosion such as pitting crevice exfoliation and environment assisted cracking is difficult to detect and degrades structural integrity. Currently corrosion control is based on costly schedule based maintenance and inspection practices. To enable more efficient condition based maintenance Luna is developing a wireless corrosion monitoring system with embedded diagnostics and prognostics. The development of a robust monitoring system for aircraft structural corrosion presents multiple challenges that include sensor system design and corrosion model development and validation in accelerated tests and service environments. Appropriate sensors must be integrated within a compact robust package that can be easily retrofit and that requires minimal operator attention. Luna is meeting the need for aircraft corrosion monitoring by developing an ultra low power wireless sensor suite with embedded processing that is compatible with energy harvesting technology to achieve very long service life. The results of Luna’s efforts in corrosion sensor development wireless sensor suite design and accelerated corrosion testing will be presented.
