Paper Abstract

There is a growing demand in recent years for lightweight structures in aircraft systems from the viewpoints of energy and cost savings. The authors have continued development of the Highly Reliable Advanced Grid Structure (HRAGS) for aircraft structure. HRAGS is provided with health monitoring functions that make use of Fiber Bragg Grating (FBG) sensors in advanced grid structures. To apply HRAGS technology to aircraft structures, a full-scale demonstrator visualizing the actual aircraft structure needs to be built and evaluated so that the effectiveness of the technology can be validated. So the authors selected the wing tip as the candidate structural member and proceeded to design and build a demonstrator. A box-structure was adopted as the structure for the wing-tip demonstrator, and HRAGS panels were used as the skin panels on the upper and lower surfaces of the structure. The demonstrator was designed using about 600 FBG sensors using a panel size of 1 x 2 m. By using the demonstrator, damage detection functions of HRAGS system were verified analytically. The results of the design and evaluation of the demonstrator are reported here.
