$6.00High Pressure Turbine (HPT) Blade

myminifactory

Jet Engine Basic Component - High Pressure Turbine Blade (Air Cooling Type) The higher the temperature at which air enters the turbine, the better the engine's performance and efficiency will be. However, there is a limit to how high the metal used in the turbine section can withstand heat. Modern engines have inlet temperatures that far exceed the melting point of most metals. The nozzles and blades in the high-pressure turbine area are particularly vulnerable to overheating. To mitigate this issue, engineers use various cooling technologies to create complex structures within these components. A model has been created to illustrate the structure and manufacturing process used in modern high-pressure turbine blades. While the actual blade is more intricate and employs additional manufacturing techniques, the model provides a general understanding of how they are made. The following sections explain the cooling system and printed models included in this package: Cooling Structure Explained by This Model Internal Cooling: Convection, Impingement, Turbulator Rib, Pedestal, Trailing Edge Ejection Outer Cooling: Film Cooling Printed Models (see photo) a.

Cutaway of HPT Blade (with Open-Close Table) Download Files * STL Files: 22 items, including the original STL file without support and a stand for reference. * STL File Name: The last two digits indicate whether the file includes support or not. Purchase Parts Information * Screws for attaching models as desired. Assembly Points * Glue "0-HPT-Blade-Mold101 + 0-HPT-Blade-Mold102". * Be careful when removing support from the "Ceramic Core". Total Net Print Time: Approximately 49 hours (estimated based on PLA, 0.4mm nozzle, 0.2mm layer height, 40% infill, and no raft or support). Note that actual print times may vary depending on your experience. 3D Printing Settings * Raft, Layer Height, Infill: Adjust according to your experience. * The models were printed using an "idbox" with a 0.4 nozzle and 1.75 PLA.
