Dedicated system for Structural Health Monitoring of aircraft hardware system based on V-cycle model

Our main subject of interest is the Structural Health Monitoring in aeronautics. Most of our works are dedicated to the detection of delamination disbonds and cracks in heterogeneous (Composite) and homogenous (aluminum 2024) structures of an aircraft structure. To successfully combine detection and alert generation we based our approach on the use of new generation of chip called SoC (System on Chip). We tried to develop an autonomous system able to detect damages on aircraft structure. According to several previous results using FPGA (Field Programmable Analog Array), PSoC (Programmable System on Chip), we proved the principle of detection embedded to a programmable system, and we also saw the limits of this kind of system for a complex system combining conditioning and algorithms of detection. That´s why we focused our effort on a more powerful chip called Zynq. The approach of development, test and implementation was based on an approach close to the V cycle. The V model represents a software development process that we adapted to the hardware conception. In this paper, we will describe our methodology and give some of the results we get during our experimentation about crack detection in aeronautic structures (Composite and Aluminum, we will also explain how development according to the V methodology helped us insure the good operation of the electronic system..
