Advancements in structural health monitoring (SHM) in aviation for enhanced aircraft safety

Abstract

This thesis investigates the advancement of Structural Health Monitoring (SHM) technologies by featuring an aircraft wing analysis which is among the key structures of an aircraft to ensure the safety and performance efficiency of its operational work. The wing structures are put under extreme strain every time an aircraft experiences a variety of dynamic operational loads and environmental conditions during the various stages of its journey. Thus, the appropriate monitoring system has to be designed and connected in order to detect the issues early on for rectifications. The study begins with a comprehensive literature review that explores the topic by evaluating the case studies and results from the practical applications of SHM for aircraft wing maintenance. The practical benefits, challenges and operational impact of Structural Health Monitoring systems in aviation industry are also discussed. The wing structure is then investigated by utilizing ANSYS that evaluate the use of SHM systems in the aircraft wing for the monitoring and analysis of critical aspects. This includes, for example, load distribution, location of stress concentrations, factor of safety and the potential area identification within the wing structure where the structural elements are likely to be damaged. The ANSYS software's in-build advanced features include the capability to develop very precise 3D designs and then ultimately providing the ways for virtual testing by installing sensors at the critical parts of the aircraft as well as simulation of the structure under various conditions of operations. An in-depth analysis of the advantages and disadvantages, as well as the practical installation complications of this extensive study would enable the researchers to get help for the optimalsuggestions. The purpose of this thesis is to obtain SHM techniques applicable and built especially for the aircraft wings that would help to enhance the safety, reliability, efficiency, and maintenance practices within the aviation industry. The present study intends to fully illustrate the SHM methodologies that are implemented comprehensively in the wing section of an aircraft. The research study also aims to enhance the objectives of providing safe and reliable flight operations and an increased aircraft efficiency in a broad sense.
