What is this?

This is a 3D printed Jet Engine Model – Medium Size – fitted with Nacelle (JET-MN).

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.

Nacelle is a housing, separate from the fuselage, that holds the engines, fuel, or equipment on an aircraft. This model features all the Nacelle Major Units: Air Intake, Fan Cowl, Thrust Reverser, and Exhaust System – all held together using strong magnets and completely detachable from the bare engine. Hence, this model can be easily into the JET-M1 model in just seconds! In addition, the thrust reversers can actually slide back and forth, revealing the cascades underneath.

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.

What does the Nacelle do?

The Nacelle determines the air needed for the engine to operate
The shape of the Nacelle helps reduce fuel burn
The Nacelle’s acoustic treatment contribute to the engine noise reduction
The Nacelle stands up to extreme temperatures to protect the engine and airplane
The Nacelle also helps take up loads between the engine and its mounting pylon, especially when the Thrust Reverser is activated
The Nacelle calibrates airflow at inlet and outlet to ensure maximum propulsive efficiency
The Thrust Reverser in the Nacelle helps reduce braking distance by 20–50%

The Nacelle comprises of some major units including:

Air Intake: Channels the airflow coming into the engine
Fan Cowl: Protect the engine and its accessories
Thrust Reverser: Redirects the bypass airflow towards the front of the engine to help brake the plane
Exhaust System: Comprising the Exhaust Nozzle and Tail Cone, it channels the hot gases exiting the engine

What makes this model perfect for STEM education?

The JET-MN model is an excellent STEM kit because:

It helps capture the attention of young students instantly and engage with them more effectively
It helps the students better understand how a Jet Engine works in simple terms, and also how the Nacelle works 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!

FAQ

Does the fan spin?

Yes, it does.
Can I remove the Nacelle completely from the bare jet engine?

Yes, you can
Can I spin the fan manually?

Yes, you can
Can the fan be driven by a motor?

Yes, the motor is an optional upgrade which you can purchase separately.
What is the motor RPM?

10 RPM as standard but can be swapped for a slower or faster motor.
Can the motor be removed when not in use?

Yes, the motor is hidden inside the exhaust nozzle and can be removed easily.
Does the model have any internal components?

No, it doesn’t.
Can the model be stripped down?

Yes, except the fan and the fan shaft – these two parts are glued together.
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.
