Turbojet Engine, 1st Generation, Double-Sided Impeller type

cults3d

This is an imaginary model of a pioneering first-generation jet engine that significantly contributed to the development of real jet engines in the 1940s and 50s. It's a unique engine design that no longer exists today, providing insight into the efforts of early pioneers in the field. This type of engine has been used for training aircraft for nearly half a century. A key feature of this model is its detailed design point: ① Double-sided centrifugal compressor with an impeller ② Inlet case featuring guide vanes ③ Duct-type diffuser ④ Can-type combustor - 12 cans (the actual engine has 14 cans) The outer cans are combined as a single assembly for easier printing and assembly ⑤ Axial single-stage turbine ⑥ Turbine cooling system utilizing ambient ram air ⑦ Front accessory gearbox B. Assembly Manual (PDF format, total 16 pages) This manual includes detailed instructions on assembly procedures, including "Parts-List," "After Printing Treatment," and "Assembly Procedure," all based on standard skills such as filing, drilling, tapping, and painting.
