JET-LU

Overall dimensions:

• Length: 642.34mm
• Height: 357.96mm
• Width (or Fan Case Diameter): 312mm

Weight: Approx. 6kg
Fan speed: 10 rpm (motorised)
Manufacturing lead time: 8 – 10 weeks
Total number of components: 400+

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. The final 3D printed Jet Engine model has more than 400+ parts fitted together perfectly. It also has a number of modules and each module was built independently and assembled together at the end in a very similar manor as to how a real jet engine is built.
* I was inspired by the 3D Printable Jet Engine by CATIAV5FTW, that’s why some parts on my model may look similar to his.

The 3D printed Jet Engine model JET-LU is an excellent kit for STEM engagement because:

• It helps capture the attention of young students instantly and engage with them more effectively
• It helps students better understand how a Jet Engine works in simple terms by being able to explore a physical model and interact with it rather than just looking at pictures or CAD model of an engine
• 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
• The model is an excellent representation of a real jet engine, meaning it can be used to engage with audiences of all age groups, from very young kids to professionals
• Finally, with its large size, high level of detail, excellent quality and finish, this model can absolutely be used as a super impressive display model!

The JET-LU has a number of additional features and upgraded features that aren’t available on the JET-LB/JET-LE version:

• The JET-LU model has a stunning matte black fan
• The JET-LU model has a more realistic-looking External Gearbox, and EEC (Electronic Engine Controller) compared with previous models
• The JET-LU model has a better design Front Engine Mount Lugs
• The JET-LU model comes with a complex/realistic-looking Engine Transportation Stand (instead of an Engine Build Stand as per previous models)
• The JET-LU model features a brand new internal gearing mechanism which allows its 3 shafts to rotate at different speeds and directions. Specifically, the HP compressor and turbine blades rotate the fastest and in clockwise direction (looking from the rear of the engine). The IP compressor and turbine blades rotate slower than the HP and in counter-clockwise direction. The LP compressor and turbine blades rotate the slowest and in counter-clockwise direction. This important upgrade makes the JET-LU far more accurate compared to the previous JET-LB or JET-LE models as it represents how a 3-shaft engine operate in real life
