What is this?

This is a 3D printed Jet Engine Model – Extra Large Size (JET-XL)

A jet engine is a magnificent machine that burns energy-rich liquid fuel and releases hot exhaust gas to generate an extremely powerful pushing force called thrust. The thrust pushes a plane forward and take you to your desired destinations across the globe.

Although a jet engine is a very complex machine, its working principles can be explained using four simple terms:

  • SUCK As the fan rotates, air is drawn in at the front through an inlet or intake
  • SQUEEZE Some of the air travels into the core of the engine and gets compressed
  • BANG When the compressed air travels to the combustion chamber, it is mixed with fuel and combusted, producing hot gases
  • BLOW The hot gases exit the combustor into the turbine, where its energy is extracted and used to drive the compressor and the fan

We designed this model to help explain how a generic 3-shaft jet engine works. This model holds an unofficial title as the ‘World’s largest 3D printed Jet Engine model for STEM‘. It was built to set a Guinness world record in 2019 but due to the pandemic, the original plan to have it officially checked and announced by Guinness was cancelled.
