Abstract
Typical airliners operate in a range of conditions, hence airborne structural health monitoring (SHM) components, must withstand the relevant environmental conditions. Additional to the integrity of the components, the SHM performance (diagnosis and prognosis) must be robust and reliable under environmental and vibration profiles during operation. This work investigates the influence of the operational condition (including temperature, humidity and vibration loads) on the integrity of a piezoelectric based SHM system in terms of integrity of the system and robustness of the diagnosis for detecting barely visible impact damage (BVID) on a CFRP panel. Consequently, compensation techniques are proposed to remove the effect of the environmental loading on the decision-making algorithm. The validity of the proposed algorithm is demonstrated on a composite plate for the operational profile defined in MIL-STD 180G standard for airborne components of a regional aircraft.
