I used to create models of "Wide cord composite fans" for comparison with propellers.
This model is the Metal Fan Blade model with Snubber (Midspan shroud) that was mainstream before the birth of "Composite fans".
Some large engines with the bypass ratio of 5: 1 have this type, but this is for engines with the bypass ratio of around 1: 1.
This type was mostly made of titanium.
The following explainable elements were incorporated at this time.
① Fan Blade, Metal Blade with Snubber (Midspan Shroud)
Full Metal (Titanium) for Low Bypass Turbofan
"All (3) Blades" can be removable and assembled by finger simultaneously.
② Fan Disk (Partial)
having "Dovetail" type slots.
