Introduction
Aircraft noise has become a significant environmental issue in recent years, with increasing concerns over its impact on human health and quality of life. As a result, there has been a growing interest in developing innovative solutions to reduce aircraft noise emissions. Smart materials, which have the ability to adapt to changing environmental conditions, have emerged as a promising technology for aircraft noise reduction.
This thesis aims to explore the use of smart materials for aircraft noise reduction and evaluate their effectiveness in mitigating noise emissions. The research will focus on the development of novel materials and technologies that can be integrated into aircraft structures to reduce noise levels during flight. By leveraging the unique properties of smart materials, such as shape memory alloys, piezoelectric materials, and magnetostrictive materials, this study seeks to provide new insights into the potential applications of these materials in the aerospace industry.
