Abstract

The optical fiber winding structure is used to make the fiber optic guided missile (FOG-M). When the FOG-M is released, if the winding structure has extrusion, which will eventually lead to the missile out of control. Based on stress analysis, a theoretical model is established to study the axial strain characteristics of extrusion during the winding process. The axial strain difference between standard and extrusion structure is calculated, showing that the axial strain in extrusion is always greater than standard structure. The axial strain increases with the increasing angle of extrusion. Distributed brillouin optical time domain analysis (BOTDA) technology is used to measure the distributed strain of extrusion at different winding layers. Experimental results show that the extrusion appears during the winding process, and the axial strain at the extrusion increases rapidly with the increasing winding layers. Theoretical calculations agree with the experimental results. This technique provides an important means for the optimization of winding process and the identification of extrusion.
