High-Precision Aircraft Engine Display Model Manufacturing Process

I. Core Component Forming Process

Fan Module Construction

Titanium alloy blades are precision cast using the lost wax method, and each blade is individually aerodynamically shaped.

The rotor disc is processed using five-axis CNC machining, and the tenon and groove areas retain the original tool marks.

The inlet duct is spun-formed using transparent PC material, and the inner wall is etched with anti-icing piping.

Combustion Chamber Components

The flame tube is laser-cut from 316L stainless steel and manually rolled into a cylinder.

The fuel nozzle array is processed using micro-hole EDM.

The double-wall structure is vacuum brazed.

II. Material Selection Scheme

High-temperature section components

Nickel-based alloy 3D printing model + hot isostatic pressing

Piping system

Annealed copper tubing followed by cold working hardening

Casing structure

Carbon fiber prepreg molded

Fasteners

12.9-grade alloy steel bolts scaled down to actual proportions

III. Surface Treatment System

Pre-treatment stage

Sandblasting: 80-grit glass beads applied to all metal components

Passivation treatment: Electrolytic polishing of stainless steel components

Primer coating: Epoxy zinc yellow primer + baked at 120°C

Functional coating

Compressor section: Gradient anodized treatment

Turbine section: High-temperature ceramic coating + thermochromic temperature-indicating paint

External piping: Color ring markings applied using laser transfer technology

IV. Detail Reinforcement Process
