$5.00Jet Engine, Single-Spool with AfterBurner

myminifactory

This type of engine has been developed more than 50 years ago. But they are still used for many military fighters.3D model for explaining the different feature comparing to the turbofan engine was designed and made. The features are; 1. Single spool with more than 10 stages long compressor rotor. 2. Half split casings. 3. Can-Annular combustion chamber. 4. AfterBurner with variable nozzle. The points of the design are; 1. For the rotation of the spool, the dummy bearing method only is prepared. 2. All stator vanes are omitted this time, because of avoiding rub of vanes and blades. But the variable vane linkage imaged parts is fitted for reference. 3. AfterBurner nozzle is too much complicated to design, then I only show the "Open" and "Close" position image only. 4. In addition, some parts that printing is considered difficult without support, are prepared STL file with support. The last of two digits of the file name is identified as "ws". In order to ease understanding about the contents of each part and the assembly order, parts breakdown and list are prepared.
