Jet Engine Component (3); Propeller

cults3d

I have successfully created a cutaway model of several types of turboprop engines. The basic component was simplified due to size restrictions on my 3D printer. Next, I expanded each part and created the actual model that explains its structure. This time it's the "Propeller" model. There are many kinds of pitch change mechanisms, with "Gear type" and "Linkage type" being typical. Please refer to a photo for both types' differences. This is a "Linkage type" because it's simpler. The following explainable elements were incorporated: (1) Blade (x4), which can be adjusted by Link, Dummy BRG, Anti Icing Boot; (2) Pitch Change Piston, moved by turning a screw instead of hydro-power; (3) Pitch Stop, featuring 2 stops (Ground Fine and Feather); other stops (Min Stop, etc.) were eliminated. (4) Interchangeability: this propeller can be exchanged with my "Propeller" (gear type). If you want this propeller to go with my "Turboprop Engine," please refer to the photo.

Purchase parts information: φ1 piano wire, screws (M2, M3, and M6). Assembly points require standard skills like drilling, tapping, filing, tightening, painting, and gluing. Assembly procedure are shown in photos; fit check between parts is crucial. Total net print time: approximately 24 hours - estimated for PLA, 0.4mm nozzle, 0.2mm layer height, 40% infill, no raft, and support. Note: adjust parameters according to your experience when printing.
