About this 3D model

[IMPORTANT NOTE] 2021.6.2 added 2021.6.16 revised==================It took a long time due to the complicated motion of this model, but finally I can develop the new model od "Motor Driven Version", so I uploaded a photo of the prototype.If you are interest in this version, please do not download these [Phase 2, 3, 4] and wait for a while.Almost parts of [Phase 1] are used in this version."Motor Driven Version" is uploaded on 2021.6.16. Object=174275================== This is the Swivel Nozzle called 3 Bearing Swivel Nozzle (3BSN) for Jet Engine for the recent STOL Fighter.For STOL, 3 Lifting Forces are used as follows;[Front] “Lifting Fan Unit” driven by Engine.[Sides] “Bleed Air Ducts” bleeding from Engine Compressor.[Rear] “3 Bearing Swivel Nozzle” directed Engine Exhaust. --- ●This ModelUnfortunately I never see the actual unit, then this is designed only my imagination.Swivel Nozzle for Jet Engine, 3 Bearing Type This model was designed in order to understand what the elements are required and how to move to get STOL position. A. Design points: This model consists of 4 Phases to get my Target Model.- Phase 1 - Basic Model. Each BRG can be turned individually by Knob. ●- Phase 2 - #2 & 3 BRGs are geared to synchronize and can be turned by 2 Hands.- Phase 3 - All BRGs are connected with Gearbox and can be turned by Single Knob.- Phase 4 - Phase 4 + Additional GB. This is my Target Model to turn Single Lever. [Note] For Phase 2～4 Model, Proto type model was made, but I am still considering improvement to absorb the big movement of #2 & 3 BRG Gear Shaft Axis. These will be uploaded in near future. B. Assembly Manual (PDF format, total 13 pages)The detail assembly manual including "Parts-List", "After printing treatment" and "Assembly procedure" are prepared based on "Standard Skill (Filing, Drilling, Tapping and painting)". C. Download files includes; - files: STL Files (15 items) - “ws” of last 2 digits means “With Support” special designed. - PDF(Zip) File: Assembly Manual D. Purchase Parts Information; - See Assembly Manual - Aluminum Tubes - φ9 - Screws Micro screws M1.4x6L - Direct screw-in to 1 mm dia hole (No nut) But there are many small parts, if you can get M1.4-P0.3 Tap, using it to make introducing thread is recommended. Quantity of screws can be adjusted by your experience. E. Total Net Print Time: Approx. 43 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. For parts having gear teeth, 100% infill and 0.2mm Layer Height are recommended.
