Jet Engine Basic Component － HPT Blade (Air Cooling Type)
The higher the turbine inlet temperature, the better the engine performance and efficiency.
However, there is the temperature limit on the metal material used for the turbine section.
Some modern engines have turbine inlet temperatures that far exceed metal melting temperatures.
The most severe high-pressure turbine nozzles and blades have the precise and complex structure using various cooling technologies.
Therefore, the model that can understand the outline of the structure and manufacturing method of the modern high-pressure turbine blades was made.
The actual blade is more complex and has some manufacturing ingenuity, but it is not reproduced because it is not an expert.
A. Cooling Structure explained by this Model (See photo)
・[Internal Cooling]
① Convection
② Impingement
③ Turbulator Rib
④ Pedestal
⑤ Trailing Edge Ejection
・[Outer Cooling]
⑥Film Cooling

C. Download files includes;
-files: STL Files= 22 items
including Original STL (without Support for reference) and Stand and Tools.
STL file name: "ws" of last 2 digits means "With Support" which special designed.
D. Purchase Parts Information;
-Screws to attaching Models as desired.
E. Assembly Points
- Not necessary special skill.
- Glue "0-HPT-Blade-Mold101 + 0-HPT-Blade-Mold102".
- Take care when removing "Support" on especially "Ceramic Core"
F. Total Net Print Time:Approx. 49 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.
G. 3D printing settings
- Raft, Layer Height, Infill: Depending on your experience.
- My models were printed by "idbox" using with 0.4 nozzle, 1.75 PLA.
I do hope you enjoy making!!ceramic-core
