The solution provides a variety of reports and dashboards to constantly monitor the health of the fleet. Remote Monitoring and Diagnostics also features automated, real-time alerts for preventive action.

Health Monitoring

Tech Mahindra’s Health Monitoring solution is built in collaboration with the Indian Institute of Science (IISc) and the Indian Institute of Technology, Chennai (IIT). The solution is designed to help MROs, airline operators and aerospace OEMs automate offline non-destructive evaluation (NDE) based structural health monitoring. The solution significantly reduces aircraft maintenance time and costs.

The solution features:

Offline Analysis based on non-destructive evaluation (NDE) centric SHM software that is automated and comprehensive

Software that works with both conventional non-destructive testing (NDT) methods and modern techniques such as Laser Doppler Vibrometry and Air Coupled Ultrasonics to analyse structural health

Condition based NDE that is triggered based on programmable rules on health and usage

Simulation Platform to visualize and assess damage and damage growth based on monitored flight data to provide repair recommendations

Prognostics to provide critical data on the residual strength of the structure and useful life remaining post-repair

Health Monitoring features a modular integrated software framework, which is customizable for a variety of aircrafts. SHM performs a variety of NDE centric tasks, such as extracting information and performing analyses, to deliver improved cost benefits.
