I have made the cutaway model of about several kinds of turbofan engines.
The basic component was simplified from size restrictions of my 3D printer.
Then, it decided to expand each component and to create the actual model which gives structure explanation.
This is the "Fan" model for comparing the feature and configuration of "Propeller".
Although, there are many type of "Fan Blade" and associated parts, this is my imagination model.
The following explainable elements were incorporated at this time.
(1) Fan Blade
Wide Code Laminated Composite Blade having metal leading edge.
Only painting is used for material difference shown.
Central two "Blades" can be removable and assembled by finger.
(2) Fan Disk
having "Dovetail" type slot for blade and attaching apparatus for "Platform Cover".
(3) Platform Cover
This is the simplified cover and attached both end side only.
Actual engine's one is more complicated and attached by using "Spinner Cone" parts.
(4) Fan Case
This is 3 layers configuration.
From inside, Honeycomb acoustic absorption panel, Fan Case and Containment Material Layer (only painted).
