FBG Sensing Technology for Structural Health Monitoring in Aerospace Industry
Structural health monitoring (SHM) is the process of detecting and assessing damage to the structural components of an aircraft. This includes fatigue cracks, corrosion, and other damage that may affect the integrity of the structure. Early detection and assessment of such damage is crucial for safety and can prevent catastrophic failures. SHM systems can also reduce maintenance costs and extend the service life of the aircraft.
Fiber grating sensing technology has revolutionized the aerospace industry's approach to structural health monitoring (SHM). The ability to detect and assess damage to the structural components of an aircraft is crucial for safety, and fiber grating sensing technology provides a reliable and accurate solution. In this article, we will provide an overview of fiber grating sensing technology, discuss its principle of operation, and highlight the challenges in SHM in the aerospace industry.
Fiber grating sensing technology has become an increasingly popular tool for SHM in the aerospace industry. It provides a reliable and accurate solution for monitoring the condition of critical components, such as wings, landing gear, and fuselage. Fiber grating sensors can detect and measure changes in strain and temperature that may indicate damage or potential failure. In this article, we will discuss the problems that fiber grating sensing technology can solve，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the structural health monitoring(SHM) in aerospace industry.
Fiber Bragg Grating Sensing Principle:
Fiber Bragg grating (FBG) sensors are the most commonly used fiber grating sensors for SHM in the aerospace industry. An FBG is a microscopic optical device embedded in an optical fiber that reflects a specific wavelength of light. When an FBG is subjected to strain or temperature changes, the reflected wavelength changes, which can be measured and used to calculate the magnitude of the strain or temperature.

Challenges in Structural Health Monitoring in the Aerospace Industry:
SHM in the aerospace industry is a challenging task due to the harsh environmental conditions that aircraft are exposed to. Aerospace components must withstand extreme temperature, vibration, and pressure conditions. Traditional SHM methods, such as visual inspection, X-ray, and ultrasonic techniques, are often impractical, expensive, or unreliable in aerospace applications.
What Problems Can Be Solved by FBG Sensing Technology:
Fiber grating sensing technology can overcome many of the challenges in SHM in the aerospace industry. These sensors can operate in harsh environments, withstand high temperatures, and provide accurate and reliable data. Fiber grating sensors can detect and measure changes in strain and temperature that may indicate damage or potential failure. By monitoring the condition of critical components, such as wings, landing gear, and fuselage, fiber grating sensors can help prevent catastrophic failures, reduce maintenance costs, and extend the service life of aircraft.
