3D model description

This is a model of the Turbofan Engine for Business Aircraft, etc.
Engine of this class has many features other than the large size jet (fan) engine.
- Smaller size
- Higher RPM
- Lighter weight
These features make the complex air flow and configuration.

Features of this model are;
①. Full length fan duct
②. Fan has boost stage LP compressor
③. Single stage Centrifugal HP Compressor (Impeller)
④. Reverse Flow Combustion Chamber
⑤. Axial stages Turbine
⑥. For the bearings (BRG), the printable dummy BRG are prepared to reduce cost instead of the metal ball bearing.

Purchase Parts Information;
-Aluminum Tubes
See each assy images

Micro screws M1.4x3.5L - Appox. 34 ea - Direct screw-in to 1 mm dia hole (No nut)
Screws M2 x *** - See each assy images

Assembly Points
- Standard Skill (such as Drilling, Tapping, Filing, Tightening, Painting and Gluing etc) is needed and perseverance too.
- If you want to clarify the air flow passage, the back side surfaces are painted before assembly.(See Photos)

Total Net Print Time: Approx. 40HR
- (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)
Especially, Input-Housing101ws.stl needs about 10 hours to print.
Note: When at actual print, each parameter may be adjusted by your experience.

I do hope your success!!

Raft, Support, Layer Height, Infill: Depending on your experience.
But the parts having blade/vane, small shaft and thin portion: 100% infill is recommended.
My models were printed by "idbox" using with 0.4 nozzle, 1.75 PLA.

Dear Asquires2006
Aluminum tubes are used in this model as follows;
01-11  7φx85L
01-12  5φx170L
03-  3φx70L
Please refer photos and images of creation about parts relation.
Thank you for message.

What is the size and length of the 3 pieces of tube? I purchased 5mm & 7mm outside diameter. I also see another smaller tube attached to mount. Would you list the diameters and lengths for me. Thanks
