Abstract:

Aircraft structural health monitoring (SHM) technology has experienced rapid development since its concept emerged. However, it faces the bottleneck in the applications for the aviation engineering now. The purpose of this paper is trying to explain the crux of the problem and provide a clear way for the next development. From the viewpoint of the evolution of aircraft structural integrity program and of the change of aircraft structure design philosophy, the necessity of aircraft structural health monitoring technology is analyzed. Aircraft structure design requirements and safety control system are discussed. The evidence strongly proves that the structural health monitoring technology, with great potential for improving the safety and reliability of aircraft structural level, reducing maintenance costs for future aircraft structures, will bring a revolutionary impact on aircraft structures design. The strategy of aircraft structural health monitoring is also analyzed. The latest progress and the development direction in the research of aircraft structural health monitoring are introduced.

Key words: aircraft structural health monitoring, structural integrity program, safe-life, fail-safe, damage tolerance, sensor
