Mini Turbofan Engine Metal Model Kit 1:20 3D DIY Aircraft Engine

Reveal the Mechanics of a Turbofan Engine

This 1/20 scale Mini Turbofan Engine Metal Model Kit (DM122) faithfully reproduces the structure and working principles of aerospace turbofan engines used in commercial aircraft like the Airbus A320 and Boeing B737. With over 150 precision-engineered pieces, this model offers a hands-on look at one of the most complex industrial machines ever built.

Assembled from high-quality aluminum, stainless steel, and zinc alloy with an anodized finish, this kit is designed for beginners and takes about one hour to complete. The finished model measures 180 x 77 x 112 mm (7.09 x 3.03 x 4.41 in), making it a compact yet detailed display piece.

Engineered Details & Moving Components

This model features a wedge-shaped fan assembly along with multiple compressor and turbine stages. Each part reflects the real engine’s design, from the floating combustion chamber to the high-pressure turbine. Follow the assembly steps to understand how air flows through the fan, compressors, and turbines in a real turbofan engine.
