CFM56-5 Turbofan Jet Engine

I saw this cool looking poster of a turbofan engine schematic and it inspired me to make a 3D rendering of it. This engine is used for the Airbus. The streamlines shown here are just for visual effect. In reality, the streamlines would be turbulent. The blue streamlines show where cold air enters and bypasses the engine (turbofans typically have a high bypass ratio). Green streamlines are shown through the compressor stages. The red streamlines show where hot gas exits the burners and turbine stage.

    Nice model! Do you have this in a compatible file format for solid works. I would like to use this 3D model on an aircraft design project with your permission.

    I do not know of any easy way to convert the model into SolidWorks. The way I created the turbofan was to draw a series of 2D profiles in AutoCAD and then revolve them in POV-Ray. The fan blades were created from an array of twisted boxes. I hope that helps.

    Great Cad model. I am curious how accurate the model is. Where did you get the 2D profiles? How accurate is the model (are blade counts accurate)?

    What is the reason for the Vortex on top of the GE Engine on the B737NG.

    Best regards, Miguel.

    Nice one.
    I was wondering, where did you get so much details? I can’t barely find any dimension about it.

    best regards
