I was a jet engine tech for 40+ years. I didn't know they came in a box ! Very cool model, would look good on my desk !

[@Chris_at_Home]

Did you ever work on JT-8s and JT-9s early in your career? I worked the assembly floor building them at P&WA for a few years in the late 1970s.

I confess. I am one of those guys that used to build models as a kid. Had planes hanging from the ceiling of my room with my ships sitting on the desk. Lionel trains, models of the human body all of that. First time viewer, I subscribed and I ordered this kit. I build my computers now so I am all setup. Can't wait to get started. Thanks for this video.

[@Andrew-13579]

So many people saying this is a turbojet not a turbofan. It sure looks like a low-bypass turboFAN engine to me. It’s a Chinese WS-15 engine for the modern J-20 fighter jet, but without an afterburner section. I believe it is similar to the F-119 low-bypass turbofan engine used in the USAF F-22 fighter jet. It has counter rotating high-pressure and low-pressure sections on coaxial shafts, like the F-119. It’s a two-spool engine. The high-pressure spool has a 1-stage turbine section that takes hot gases from the combustor section and drives the 6-stage, high-pressure compressor. It rotates counterclockwise when viewed from behind the engine. The low-pressure spool’s 2-stage turbine section takes hot gases passed on by the high-pressure turbine and uses that energy to turn the low-pressure compressor/fan stages. The bypass ration is 0.25:1. The low-pressure section rotates clockwise. The 3-stage fan and low-pressure compressor clearly has a path of airflow in which some air bypasses the high-pressure section. Turbojet engines do not have an driven airflow path that bypasses the combustion chamber.

[@chittychad18]

Its not a low bypass turbofan, its a turbojet. All the air is directed to the low pressure turbine

[@averagedrip2588]

@@chittychad18wrong, clearly there are splitter shields there😂

[@shamsulhassnainbaig6264]

Very good nice achvment for new Lerner how to working?

[@mp7986]

Cool but the low pressure compressor and medium-high pressure compressor based on the orientation of the blades should be rotating in opposite directions👀👀

[@theresacaron4238]

Cameras always show propellers and turbines rotating in the wrong direction due to the camera, not the kit or actual turbine.

[@HekateMGO]

@@theresacaron4238 this isn’t about the camera, the blades are actually oriented differently and the little planetary gearbox actually makes them turn in opposite directions.

[@leadsolo2751]

It's the Stroboscopic (Strobe) effect

You are correct. You can see it well @9:32

[@giveitatryguy6784]

@@kotascalemodel totally welcome.. I would now like to get one of these models myself I'm in new zealand so I'll have to hunt around. although I am in process of making my own small scale fuel running jet based on the j79 wich is my favourite wich is taking time as I'm hand building no printer or special tools just basic tools

[@KELLEMWITIT]

satisfying to watch

[@rocketscience777999]

This is a model of a single spool gas turbine engine from the 1950's. Most modern engines have a high pressure spool (HP compresser/turbine/shaft) and a low pressure spool (LP compresser/turbine/shaft) with the LP shaft inside of the HP shaft.

[@wiffy1346]

the box says it's ws-15, the latest Chinese fighter jet engine the ws-15 is indeed a twin spool engine, but as a scale model, it may have omitted the shaft-in shaft mechanism Edit: nvm, I think they represented the twin spool by having yellowish shaft for the HP and metal bar for LP, and having gearbox to differentiate the turning speed

[@Greatdome99]

It is indeed a two-spool engine, since the planetary gears in the model simulate airflow coupling of the two (shaft-in-shaft mechanism).

[@randywilliams7281]

I would love a model of a GE CJ610 turbo jet or its military version the J85. So very simple and straightforward and many of us learned on those engines

[@sleeperjazz_04]

This feels like an asmr unboxing

[@rocnnrollbus]

If they made a model of this quality for the Allison/Rolls-Royce T56 with the gearbox and Hamilton Standard propeller (C-130E/H), I'd buy one tomorrow 😊👍 Spent 14 years in the C-130 community as a mechanic and flight engineer.

[@alanw2235]

Nice model and very cool but I think they could of been a bit more precise on the fit of all the blades that actually rotate because when you tuned it on the blades were wobbly and that just looks bad.

People who say this is a turbojet engine don’t know what they’re talking about. It is a LOW bypass turbofan as used in modern fighter aircraft. HIGH bypass turbofans as used for commercial airliners have that signature very large diameter fan that everyone pictures when they hear‘turbofan’.

Is that copper spot on that saint gaudens? Presence of boiling water and baking soda in a cup/bowl upholstered by aluminum foil will remove it. Try it on other coin. This also removes toning on silver, not milk spots.

[@get2dachoppa249]

Its a low-bypass turbofan, the kind used in fighter aircraft (GE F110, PW F100, GE F414 for example). The bypass air is used in the afterburner section to support combustion and for cooling purposes.

[@AgentJayZ]

And this engine will handle the combustion and flames inside?

[@Wildlifesupernannyfan]

Did it go 100,000 rpm?

[@mrbuttocks6772]

You could 'simulate' an active engine by just burning some incense in front of the model and using a proper fan to blow the smoke into the model as it spins!

[@djwhu77]

It’s such a shame the motor is so noisy - would have been great to have a near silent motor and USB powered

[@Berliner079]

This is NOT a turbofan engine. Because a very important part is missing: the FAN in front of the turbine inlet for the bypass flow. This is a normal jet engine

[@berk6258]

The rotation direction of the LP shaft is wrong :) This is a contra-rotating shaft concept but you are rotating them in the same direction.
