Turbofan Engine, for Business Aircraft, Cutaway

cults3d

This is a detailed model of the Turbofan Engine for Business Aircraft and similar applications. This engine type boasts numerous features beyond those found in typical large size jet engines. They include smaller size, higher RPMs, and lighter weight - all contributing to intricate airflow patterns. Key characteristics of this particular model are: ① The full-length fan duct allows for optimal air flow. ② The fan itself has a boost stage LP compressor, increasing efficiency. ③ A single-stage centrifugal HP Compressor (Impeller) enhances power output. ④ Reverse Flow Combustion Chamber optimizes fuel combustion. ⑤ Axial stages Turbine ensure efficient energy extraction. ⑥ To minimize costs, printable dummy BRG are used instead of metal ball bearings. The downloadable files include: - 29 STL Files, each named "ws" for those with support structures and designed specifically for that purpose. - Images providing assembly guidance to facilitate easy reassembly. Purchase information for required parts is as follows: -Aluminum Tubes - refer to assembly images for specific requirements. -Screws: Micro screws M1.4x3.5L are needed in approximately 34 units, which screw directly into a 1 mm diameter hole without the need for nuts. Screws of size M2 x *** can be found in assembly images. Assembly points require standard skills such as drilling, tapping, filing, tightening, painting, and gluing, along with perseverance. For clarity on air flow passage, it's recommended to paint the back side surfaces before assembly (refer to photos). The estimated total net print time is approximately 40 hours for PLA material using a 0.4mm nozzle, 0.2mm layer height, 40% infill, and no raft or support. Specifically, Input-Housing101ws.stl requires about 10 hours to print. Please note that actual print parameters may vary based on personal experience.
