Sounded like a bag of bolts being shook.

[@Petriefied0246]

Jet engines usually do at low speed.

[@Alex50969]

That are the blades of the compressor. There are several reasons for that: 1. Easy Installation and removal 2. As the engine spins faster the centrifugal forces will push them outwards with hundreds of G's, reducing the vibrations 3. It leaves space for thermal expansion For the model you dont need any of that obviously, but in a commercial airliner thats another story

[@chrisprobert6]

Ha. Bag of bolts would be more useful ,to me. Good but of fun tho'😅

sad the tolerances are so bad could have been a really nice model rotating silently

[@Noman1000]

you should hear what it sounds like when an actual jet is windmilling on the ramp

[@Billskins4dayz]

@Noman1000 i know they make some noise but it's not necessary with a model or they could have tightened the tolerance and had an explanation on a plaque with the rest of the information

[@njones420]

@@Billskins4dayz The noise is the individual blades moving when it's not spinning fast...the real ones do the exact same thing.

[@Billskins4dayz]

@njones420 I know this but it ruined a nice model on this I'd choose functionality over accuracy when it's never actually going to see heat to shrink tolerance

Awesome! I'm a former Turbofan Test Engineer for Lockheed and Rolls-Royce at Stennis Space Center, from 2007-2012, testing the Trent 900, 1000, and XWB engines for the Airbus A380, Boeing 787, and Airbus A350. I've got to get me one of these!

[@salmiakki5638]

God the Trent XWB is beautiful. Btw, can I ask you one thing I couldn't find the answer online? I've seen the inside surface of the air intake/nose cowl to be perforated with small holes. Is it actually blown to remove the boundary layer? Or is it just a texture to reduce the viscous friction?

[@superskullmaster]

@@salmiakki5638why can’t it be both? 🧠

For the cost i would expect that to be machined better. Cool table piece though.

[@Failure_Is_An_Option]

Says the clown that has zero machining and engineering knowledge or experience.

[@theOriginalskillr]

For that cost id expect it to be fully functional

[@aserta]

You should shim up the blades with paper so it doesn't sound like someone threw a bag of pennies inside that thing. :))

[@chris1451]

Why? Real turbofan engines sound like that when they rotate slowly. The fan blades are loose on purpose.

[@THISLOVETHISHATE99]

models are cool and all but u know what could be even cooler one of these that actually operates like a real one

[@MTBCrafter]

3:00 if you wonder what these tubes are for: This is called Low Pressure Turbine Active/Passive Clearance Control (LPTACC/LPTPCC). All these tubes have small holes on the inside and they blow cool air at the LPT Case. This is done to ensure a small tip clearance between the turbine blades and the case to achieve a higher efficiency. The difference between active and passive is the presence of a dedicated valve (active: there is a LPTACC Valve - passive: no valve). This is a nice model for educational purpose however I'd prefer a two shaft model (obviously more complex but also more accurate). Thank you for sharing!

[@KefirTView]

I'm watching the assembly of this turbofan engine and having one continuous thought while seeing all of these parts coming together......." I am never boarding a commercial airliner again!"

[@locouk]

I was looking at it thinking the tolerances were lousy and wondering if it would be rectified on tightening all the fixings, now I know why it’s not a working model.. My dreams are shattered! lol 😅

True when you fly in Boeing planes, which is about 41% in China.

With the runout of the turbine visible when looking in from the rear of the turbine , if you spun that up it would scatter extremely destructively. Something doesn't seem right because it sounds like a washing machine filled with bolts and nuts

[@davidgriffiths4844]

It’s an educational model, it is not intended to achieve the strength, tolerances and frictionless operation of a real jet engine! If it did it would be much more expensive!

[@gunggerdin1]

@@crashwelder5337, at low rpm, the front stages of the engine have their blades pinned and are able to move 5 to 10 degrees about the pin, the noise is something else at 20 to 80 RPM. It does sound exactly as you describe.
