Aircraft Structural Repair Technology Using Smart Actuators

The aim of this project is to develop a smart repair kit to effect efficient field repair of a damaged , aircraft structure. The composite repair process consists two steps a) bonding an annular ring using ' bi-functional property of the Shape Memory Alloy (SMA) based repair. device which applies both heat and pressure and b) bonding a flush patch taking its support and novel vacuum assisted tripod stand method. This report deals with the development of smart repair kit from conceptualization to realization. Using the developed smart repair kit, many repair trials were conducted arid tested. This report details the experiments and observations related to the smart repair kit
