Automated ultrasonic inspection of aerospace composites with enhanced defect detection probabilities aided by gantry deployed,CAD controlled robotics
Future generation aircraft will consist mostly of carbon composite materials. The modes of failure in composite intensive aircraft are not fully known as they are still near the beginning of their design life, although they are susceptible to internal impact damage, not visible at the surface. Current non-destructive inspection (NDI) of composites in production and service is still largely manual with low area coverage and images difficult to interpret because of macroscopic structural anisotropy.
To address these problems the project proposes two key NDI innovations:
- Up to 100% volume NDI coverage using gantry deployed, CAD controlled robotics so that inspection records at any point can be accurately compared at successive maintenance downtime intervals to allow health diagnostics and prognostics.
- A step increase in current detection probability for composite defects implemented through an inference engine performing similarity analysis on spatial and temporal changes in images with coherent noise removal performed by advanced signal processing.
This project was co-funded by the UK’s innovation agency, Innovate UK.
