Model making scheme for aviation turbofan engine

1、 Model presentation elements and characteristics

The aviation turbofan engine model needs to showcase its internal structure and working principle, with core display elements including:

Fan System: Showcasing Large Fans and Their Blade Structures

Compressor: Angle and spacing of multi-stage compressor blades

Combustion chamber: flame tube and fuel injector model

Turbine system: blade array of high-pressure turbine and low-pressure turbine

Exhaust system: tail nozzle structure

Dual channel design: showcasing the airflow paths of the inner and outer channels

The characteristic of the model is to display the internal structure through sectional design, which is suitable for aviation exhibitions, education and training, and enterprise technology display scenarios.

2、 Material selection

Main structural materials

Shell: ABS engineering plastic or aluminum alloy, balancing lightweight and metallic texture

Blade: Carbon fiber or aviation aluminum, hot pressed to ensure accurate bending curvature

Compressor/turbine: CNC machining or high-precision 3D printing materials

Base: Wooden or metal frame to ensure stability

Special effect materials

Transparent acrylic (for sectional display)

Micro motor (drives fan rotation)

LED strip (simulating the brightness of the combustion zone)

3、 Production process

structural design

Cut open design: One side of the shell can be disassembled or replaced with transparent material to display the internal structure

Scale: commonly used 1:5~1:20 scale, retaining the core structure

Dynamic system: Micro motor drives fan rotation, combined with LED lighting to simulate combustion effect

Core component production

Fan and compressor: proportionally restore the angle and spacing of multi-stage blades

Combustion chamber: Create models of flame tubes and fuel injectors, with some models featuring transparent sections

Turbine and nozzle: blade microfabrication to maintain true streamline shape

Axis structure: Maintain structural integrity, even if it does not transmit real power

Assembly process

Install shaft system and internal components

Assemble compressor and turbine blades

Install combustion chamber and nozzle

Installation of shell and transparent panel with cut surface

4、 Post processing and coloring

Surface treatment technology

Metal paint spraying: using standard colors such as industrial gray and equipment blue, spraying in three layers (primer color paint protective paint)

Aging treatment: lightly polish the edges of the equipment to simulate usage marks

Identification production: Using water sticker technology to add equipment nameplates and safety signs

Dynamic effect implementation

Flow light effect simulates production rhythm

Breathing light display device in standby mode

Fault alarm red flashing prompt

Detail enhancement

The cable is made of thin copper wire to increase realism

The operation button adopts a micro switch, which can be actually pressed

The display area uses semi transparent acrylic to simulate LCD effect
