Turboprop Propeller

cults3d

This propeller is designed specifically for "Turboprop Engine" (Thing: 2406596). Key features of the propeller include: (1) Four robust blades (2) A variable pitch mechanism that can be adjusted (3) Counterclockwise rotation when looking forward (4) A reduction ratio of approximately 0.1 (5) Anti-ice heater boots bonded to the leading edge of each blade, although they are painted at this model Every part of the propeller is carefully designed based on actual engine and aircraft pictures. The pitch change mechanism used here differs from that of an actual propeller. To avoid gear teeth jumping, it's essential to rotate the mechanism in the same direction using both hands when changing pitch. Downloadable files include: * STL Files * Images: STL File Figures, Parts, and Propeller Pictures For purchasing parts information, you'll need: * Bearings: Stainless steel balls with a diameter of 3mm - approximately 40 pieces * Screws: M2 x 10L screws - 2 pieces, along with an M2 Tap for use (see picture) Assembly points are as follows: * Steel balls are carefully inserted into the recess of Spinner-Body01 to maintain outside bore contact. * Four blades with Spinner-Blade04 (No.1) are inserted into Spinner-Body01, aligning all blade angles. * For engine attachment, an M3 Tap hole in the propeller shaft is used if desired. Total estimated net print time: approximately 15 hours. Note: This estimate is based on using PLA material with a nozzle diameter of 0.4mm, layer height of 0.2mm, 40% infill, and no raft or support. Parameters may be adjusted when printing the actual model. [Update 2018.11.24]: A note has been added to remind users of the correct pitch change action.
