myminifactory

This is the Variable Nozzle for Jet Engine Afterburner (Reheater, Augmentor). There are several types of Variable Nozzle. This is the Full Link Type as imagined. This model was designed to understand what elements are required for Variable Nozzle mechanism. A. Design points: 1. A cutaway model to see Mechanism and Nozzle Movement. 2. Open/Close of Nozzle can be done by a tool. 3. A Ball Joint is used at one end of the Link rod only, because it's too small to print. 4. This can be disassembled and assembled with screwdrivers. Related to this, the Flap total quantity is limited to ten (10). Seven (7) flaps are used for this cutaway. 5. Open/Close diameter ratio is about 1.35 (=1.8 area ratio).

B. Assembly Manual (PDF format, total 22 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)". My design hole diameter is considerably smaller than the finish hole diameter in order to ensure the wall thickness at the time of printing. Then the following drills and Tap required. Drill: φ1, 1.5, 2, 2.5, 3.5, 5.2 Tap: M1.4 (Optional), M2, M3. For the parts having small ball end, carefully drill to finish hole, then carefully break ball stickiness. If ball comes out part, use suitable size washer and your printed plate at assembly. C.
