Abstract
In order to meet the requirements of damage detection and interface debonding detection of solid rocket motor (SRM) composite case, a novel embedded femtosecond grating array was proposed to measure the strain parameters of SRM in real time and online, and the strain parameters were used to reflect the damage and debonding state of SRM structure. The mechanical analysis and simulation of the SRM are established, and the multi-layer strain transfer model between the sensor and the SRM is proposed. A high-performance femtosecond grating array is inscribed and effectively coated and packaged. And overcome that technical problem of shell and interface implantation. The debonding simulation experiment was carried out. For the first time in the world, the production, storage and ignition stages of the SRM were effectively monitored. The strain distribution state in the whole life cycle of the SRM is given. It provides data support for the evaluation of SRM structural integrity.
