Zeto.r:Build Your Own Full Metal High Bypass Jet Engine Model Kits & HOW Does It Work|Stirlingkit

Learn how jet engines work by assembling this DM 119 turbofan aircraft engine model with aerospace engineer Zeto.r
If you are interested in jet engines or have always been curious about how they work, this DM 119 engine model will provide you with a unique learning experience. In this article, we will follow aircraft engineer Zeto.r to disassemble this model from StirlingKit to learn how it is assembled step by step and reveal the complex engineering design and working principles behind it.

1. Unboxing: Thousand Parts Challenge
First, Zeto.r showed us the huge box of this engine model, which contains thousands of metal parts. Each part is carefully numbered to ensure that you can easily find the right part to assemble. This detailed design not only helps you complete the model assembly step by step, but also allows you to learn the function of each part and how they work together.
The design of the model is very close to the real jet engine, especially in some components, the manufacturer has handled the details very well, even the position and fixing method of the screws are extremely thoughtful

2. Assembly process: from basic to complex
Zeto.r started with assembling the "fan disk". In the first step of assembly, he connected the N1 shaft and the fan disk together and used this N1 shaft to drive the fan. The power of the fan comes from the low-pressure turbine, which relies on the heat energy generated by combustion. Zeto.r mentioned that special attention should be paid to balance when installing the fan blades, because if the blades of different weights are not installed properly, it may cause the shaft to vibrate and affect the operation of the entire engine. This detail is highly consistent with the design principle of the real engine. In this way, you are not only assembling the model, but also deeply understanding the basic structure and operation mechanism of the engine.

3. Understand the core components: low-pressure compressor and high-pressure turbine
As the assembly progressed, Zeto.r came to install the high-pressure turbine and low-pressure turbine. The high-pressure turbine is subjected to extremely high temperatures, usually between 1500°C and 2000°C. Therefore, its turbine blades need special cooling treatment to prevent overheating damage. During installation, Zeto.r paid special attention to the material and cooling structure of the turbine blades, trying to match them with the structure in the real engine.

The low-pressure turbine is responsible for collecting the remaining heat energy to drive the large fan and low-pressure compressor, which are key components of the engine to generate thrust. Zeto.r pointed out that the design of this part is very clever. By adding multiple stages of turbine structure, the manufacturer successfully achieved low-speed high efficiency and ensured sufficient thrust output.

After completing the installation of the turbine, Zeto.r continued to install the gearbox and drive shaft. The function of these two components is to support the rotation of the N1 shaft and transmit the power of the engine to other components. The installation of the gearbox and drive shaft is crucial to ensure the smooth transmission of engine power.

4. Operation of complex systems
Although the design of this model simplifies some complex details, it still truly restores most of the working principles. For example, the transmission system between the low-pressure turbine and the high-pressure turbine, how to transmit power through a sophisticated gearbox to ensure the efficient operation of the entire engine system. Zeto.r emphasized that every part of the model has been carefully designed to ensure that you can deeply understand how each component works together during the assembly process.

5. Final test: Make the model work
When all the parts are installed, Zeto.r conducted a final test to ensure that the model can run smoothly like a real engine. He demonstrated how to test the operation of the model to ensure that every detail is accurate. After the final adjustments, the entire jet engine model was assembled and showed functionality and refinement similar to the real engine, allowing the audience to more intuitively experience the working principle of a high-performance jet engine.

Not only a model, but also a deep learning!
Through this DM 119 engine model, you can not only experience the fun of assembly, but also deeply understand the complexity and engineering design of jet engines. Whether you are curious about aviation engineering or are looking for a model that can challenge your manual skills and learn practical knowledge, this engine model can bring you an unparalleled experience.
Regarding the price, $1000 (now there is a 20% discount, only $800)
Yes, some people may say that it is too much, but compared to that
The turbofan aeroengine that costs $250 is made of plastic, but this DM119 aeroengine is made entirely of metal and you can really feel it thanks to the weight and the amount of detailed information you can find. From my point of view if you want to do some aviation geeks. Be glad that you have a spare aeroengine. This can be a good choice for you, Zeto.r said.
