High Pressure Turbine (HPT) Blade, Air-Cooled

cults3d

High-Pressure Turbine Blade (HPT) Component - Air Cooling Type The higher the temperature at the turbine inlet, the better the engine performance and efficiency will be. However, there is a temperature limit to the metal material used for the turbine section. Some modern engines have turbine inlet temperatures that far exceed the melting point of metals. The most severe high-pressure turbine nozzles and blades have precise and complex structures using various cooling technologies. Therefore, a model was created that understands the outline of the structure and manufacturing method of modern high-pressure turbine blades. The actual blade is more complex and has some unique manufacturing features, but it cannot be reproduced because it requires an expert's knowledge. 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] ⑥ Film Cooling B. Printed Models (See Photo) a. Mold for Ceramic Core (Convex Side) b. Mold of Wax (Convex Side) c. Ceramic Core (with Rotary Table) d. HPT Blade (with Rotary Table) e. Cutaway of HPT Blade (with Open-Close Table) C. Download Files Include - 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 is Special Designed. D. Purchase Parts Information - Screws to Attach Models as Desired. E. Assembly Points - No Special Skill Needed - 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 0.4mm Nozzle, 1.75 PLA. I Hope You Enjoy Making!!
