A bi-mode state monitoring system for aero-engine components based on FBG sensing

The establishment of a state monitoring system for the aero-engine and its key components is of vital importance to reduce the risks and costs of aero-engine operation. Based on the novel fiber Bragg grating sensors (FBGs) embedded in the aero-engine, a bi-mode state monitoring system for the components in aero-engine was presented in this paper. A 3D model of the blade and FBGs were constructed and controlled in this system. Moreover, the temperature detected by FBGs can be simulated as a temperature field on the model. In order to acquire the expansibility, flexibility and security, both B/S (Browser /Server) mode and C/S (Client/Server) mode of the system were established in our system. Therefore, it is feasible to monitor and simulate the state of rotating blade in aero-engine through various FBG sensors and our system.
