How do I establish a three-dimensional model of the fan and analyze the fan noise based on the created 3D model?

Analysis of fan noise in the CFM-56 engine.
Does anyone know where can I get the engine's geometric parameters? I tried searching but couldn't find any viable results.
This is my assignment, I would really appreciate it if someone could help me out with the parameters so I model it in CATIA and export the file into ansys for analysis. Thanks
