Abstract

In order to improve aerodynamic performance and efficiency, monitoring exact internal structure changes of the aero-engine under various operational statuses is a very important and meaningful job. In this work, we design a novel x-ray process tomography system to monitor the aero-engine internal structure changes under different rotating speed without physical disturbance. However due to the dynamic measurements and high rotating speed of the aero-engine blades, the system faces more challenges than conventional ICT system both on the data acquisition and on reconstruction algorithms, which are discussed in detail here. Some feasible solutions with corresponding experimental results are also presented.
