This is the Turbofan Engine currently used with the Big Passenger Aircraft.
I made this model to compare the 2 Spool Engine and the Geared Engine for Mid Class Passenger Aircraft.
A. The features are as follows.
① Typical 2 Spool Turbofan Engine for Big Size;
a. Single Stage “Fan” (Metal Type, 3m class Diameter)
b. Compressor: LP (Boost 6 Stages), HP (11 stages)
c. Turbine: HP (2 stages), LP (7 stages)
d. Gearbox is installed to Core side.
② All stator vanes are omitted to avoid rubbing with blades.
③ No metal bearing is used.
④ Can be disassembled and assembled (But please at your risk)
B. Assembly Manual (PDF format, total 15 pages)
The detail assembly manual including "Parts-List", "After printing treatment" and "Assembly procedure" are prepared based on "Standard Skill (Filing, Drilling, Tapping and painting)".
C. Purchase Parts Information;
φ4, 6, 8 See Parts List
Micro screws M1.4x3.5L & M1.4x6L - Direct screw-in to 1 mm dia hole (No nut)
But if you have the M1.4 Tap, it will be very useful.
Screws M2 x ** - See Parts List
D. STL file
Total STL files are 34 items including the stand and tools.
“ws” of last 2 digits of file name means “With Support” special designed.
E. Total Net Print Time: Approx. 76 HR
- (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)
Note: When at actual print, each parameter may be adjusted by your experience.
F. Printing settings
Raft, Support, Layer Height, Infill: Depending on your experience.
My models were printed by "idbox" using with 0.4 nozzle, 1.75 PLA.
I do hope your success!!
