| Abstract: | Timely and accurate detection the cracking, corrosion, delamination, material degradation and other types of damage in an air vehicle structure is essential to ensure the safety and reliability of in-service aircrafts. Structural health monitoring (SHM) technology is regarded as a revolutionary method for determining the structure integrity. It plays an important role in aircraft design, flight and maintenance. The application of SHM can improve flight safety, reduce maintenance costs. The system composition, basic principles and key technologies of SHM are introduced in this article. Through examples, the application of SHM technology for air vehicle based on SMART Layer is also elaborated in this article. |
