Jet Engine Component; Axial Compressor - Circumferential Dovetail Slot Type

myminifactory

There are several types of axial compressor rotors, including Disk and Blade varieties. I previously designed a dovetail type disk and blade assembly as part of an axial compressor VIGV and Stator set, which can be found at https://www.myminifactory.com/object/3d-print-jet-engine-component-axial-compressor-75164For the rear stages of HP compressors in modern engines, a circumferential dovetail slot type rotor is used. This method allows for easy blade installation using an allen wrench only, making it ideal for the "Drum Type Disk" design. A partial model of this assembly is provided to demonstrate how blades and locks can be attached to the disk.The following parts are included:(1) Disk - Circumferential dovetail groove(2) Blades - 6 total, with 3 types of circumferential dovetail slots(3) Locks - 2 ea(4) Screws - Internal Hex head - 2 ea(5) Assembly Stand and Blade StopsDownload files include STL Files (7 items), with "ws" indicating the use of special support designs.Purchase Parts Information:Screws - Internal Hex head (Stop Screw) - 3mm x 10mm - 2 eaM2x8 Screw - 2 ea (Tool)Assembly Points: Standard skills such as drilling, tapping, filing, and tightening are required. Detailed assembly procedures can be found in the "Photo-Book01.pdf" document.Total Net Print Time: Approximately 12 hours (estimated using PLA, 0.4mm nozzle, 0.2mm layer height, 40% infill, no raft, and support).Note: Actual print times may vary depending on experience. My models were printed with a "idbox" 3D printer using a 0.4mm nozzle and 1.75 PLA filament.
