Description
Zifan He and colleagues built a system to pinpoint where a gentle impact struck an aircraft panel made of carbon fiber over a honeycomb core. Such soft hits can dent inner strength without clear surface marks, a safety risk. Their system listens through a web of fiber sensors glued to the panel, which bend light as the panel flexes.
A fast learning method then sorts the signals to name the strike spot in real time. The team tuned the method to stay sharp even when sensors sample at high speed, a known weak point. Tests showed strong accuracy for these low-energy hits. The authors aim at live damage watch on flight structures.
