JET-M2
Price range: £20.00 through £200.00
This is a 3D printed Jet Engine Model – Medium Size – Design #2 (JET-M2)
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.

How was this model designed?
This model was designed using publicly available material from the internet including CAD models, videos and pictures of the real jet engines from various aerospace companies.
A few months after I introduced the first design of this model (JET-M1), I was approached by many people with the same question: “Can you design this engine model to be stripped down into modules?” I wasn’t really keen on doing that until one day, I saw a super cool robot – e.Do! The e.Do robot is an excellent STEM kit, which can be easily programmed through an app to pick and place lightweight items. I immediately thought: “Hey, wouldn’t it be really cool if I could program this robot to build a Jet Engine?” So, I decided to redesign my medium size Jet Engine model again. Externally, this new model JET-M2 looks exactly the same as the JET-M1, however, the casing is no longer printed as one single piece, meaning that you can actually split the engine into modules e.g. Fan, Intermediate Case, HP System, IP Turbine, LP Turbine/Tail Bearing Housing, and Exhaust Nozzle. Each module is attached to each other using magnets, hence, the engine can be stripped down and assembled within seconds!
What makes this model perfect for STEM education?
The 3D printed Jet Engine model JET-M2 is an excellent STEM model because:
- It helps capture attention of young students instantly and engage with them more effectively
- It helps the students better quicker understand quickly how a Jet Engine works in simple terms by being able to explore a physical model and interact with it, rather than looking at pictures or CAD model of an engine via an app
- The model is made by 3D printing, hence, it helps spark interesting conversations with the students about how technologies such as additive manufacturing are revolutionising the engineering industry today and how they can learn the skills that would benefit their careers in STEM in the near future
- Finally, with its small size, excellent quality and finish, this model can also be used as an award, trophy, gift or simply a super cool item in your personal aerospace collection!
Frequent questions
-
Does the fan spin?
Yes, it does.
-
Can I take the engine off the stand?
Yes, you can.
-
Can I spin the fan manually?
Yes, you can.
-
Can the fan be driven by a motor?
Unfortunately no, the motor is only available on the JET-M1 only.
-
Does the model has any internal components?
No, it doesn’t.
-
Can the model be stripped down?
Yes, this model can be stripped down to piece part level.
-
Does it work like a real jet engine?
No, this is only an educational model so please don’t put it on your RC airplane.
