my homemade compressor turbines.

[Conorsev]

mad dude :) i love making these in my lunch break at work :P

[deltaxcd]

as mentioned these are quite useless turbines and mostly because you cant stack them with good tolerances and these things cant run at any useful speed because blades will be ripped off.

correct version of turbine must be completely flat disk so that you could stack few of these things and get some useful compression.

[Jdspitz2]

None of those are compressor wheels, they are just simple fans cut out of sheet metal. There is a very specific science behind axial compressor wheels and unless you are very good at physics, fully understand the aerodynamics of a venturi, and can put the aerodynamic principles together, those will never work.

[deltaxcd]

@Jdspitz2

it is not that hard.

there is no big science axial compressor are actually just fans stacked together complexity arises from the need to prevent leaks so quite tight tolerances must be maintained. and fans must be made in a way to avoid usual empty spaces and gaps.

[Jdspitz2]

@deltaxcd I have a college degree in Aviation. I used to be a mechanic that worked on airplanes. I also build little jet engines like the one you have just for fun. And mine actually work! I know exactly what I'm talking about. And yes it is that hard.

[deltaxcd]

@Jdspitz2

nobody is questioning your knowledge, but it is stupid to say that something is just too complex for lowly commoners without any further explanations.

If you claim that it is hard then explain what is so hard and how these primitive turbines will  fails or what should be improved.

[Jdspitz2]

@deltaxcd You are under the impression "this isn't rocket science" Well actually yes it is. The length, width, shape, and airfoil of the blades is critical. The next thing is stator vanes. Without stator vanes between each stage of the compressors, you will never get compression. The problem with your design is the blades are way too long. They should be much smaller. For a turbine wheel exposed to heat, you have to use steel and it has to be twice that thick or it is going to warp.

[deltaxcd]

@Jdspitz2

seems that you think I am an author of this video but you are mistaken.

I said almost exactly same as you here in my another post. but I do not agree that is is big science, bigger problem is to manufacture everything properly.

I am designing something like that but it is turbomolecular pump not jet engine. and biggest problems is to make sure that turbine will not leak or disintegrate under such extreme speeds, while everything else is secondary.

[Jdspitz2]

@deltaxcd

Hmm, I did mistake you for the author of this video.

Ultimately, for jet engine purposes, you want a turbine machined out of Inconel on a 5 axis mill with tolerances of +/- .005". Turbomolecular pumps are similar in design but unlike turbine engines, do not require the calculation of fluid dynamics making them much easier to design. For YOUR purposes, you are correct in that there is much less science behind it.

[Daimo988]

simply put..........will not perform, period

[352shan]

put all of them in ur ass

[MetropolitanPolice52]

I think its great to see people try various projects. Thats how the light bulb was made. (well it was stolen from Nicolas Tesla but who cares about that right? haha. Keep up the great work looks interesting.

[egorkarus]

forget it or go buy cnc\learn to use it about year and come back lol

[s1l3ntw1]

@egorkarus Or just pay a shop to spark erode/edm... machining will build up too many internal stresses = turbine rupture @ speed

[BOOOZB]

Funny indeed, but except for hair dryer , what do you expect to do with it ?

[TheSupertecnology]

how´s that tool named at 1:20?

[simonfokos]

there are good for pc fan use lol



[Daimo988]

@simonfokos i wouldnt put it in my pc, way too unbalanced to trust it around my gpu

[zero00tolerance]

Hi very good try my friend ! I have always wanted to make my own jet engine .. i have tried the exact method as yours... but i realized to achieved jet engine effect =( we really needed metal blades.. to prevent it from melting. It was a good try though we did it my friend we did it..

[mickelmaxor]

nice job , hey what is the name of the tool you used ?

[soverato3]

can they work in a real small homemade jet engine or will they melt??

[19wael96]

no they wont melt .

[demonofrazgriz333]

@19wael96 they just might explode tho...

[krazzykid101]

im sorry sir but the one on the bottom right [at begining] doesnt seem like it would work too well, if so how does it work?

[Sitro951]

Данная в видео " гопота " , для реактивного двигателя никогда в жизни не подойдёт!!! Во-первых данные винты не выдержат температуры; Во-вторых их будет гнуть на изнанку!!! Так что сие изделия -тоже что и картонное колесо к БелАЗу!!!

This a video gopota, for a jet engine never fit! First Data screws will not withstand the temperature, and secondly they will bend on the wrong side! So these things, too, that the products and cardboard wheel to BelAZ!

[19wael96]

sorry but your comment is not clear .

[Unasigad]

@19wael96 LOL!! :D

[Unasigad]

@19wael96 Nice job mate. How do you shape and bend the blades? ;)

[blackend00]

nice i use the same way to make trubine ;)...and if you want to make the impeller try to add a conic form or make to stage for the turbine ..i'm making one now when i finch i well make a video

[19wael96]

nice

ok im looking forward for your video buddy send me a message on you tube for the link when you upload it

thanks .

[Artist334]

Have you tried these running?

[19wael96]

yep i tried them all on my drill !!!

[dj7310]

could u make a tutorial?

[19wael96]

read the discription

and click on the link

[deaftodd]

I have thought of this many times but I realized that the radial cuts toward the center is making the blades weaker especially hi flow application.

[Lineracing]

Cool!! :)

[IntegralDischarge]

Hey. Nice work. I tryed to make one too but unfortunately it didnt work. The axis doesnt spin easily (altough i used 2 ball bearings). So what are you using to hold the axis? And also how much space are between blades and side of the engine because mine is about 2 mm

[19wael96]

i use a boat shaft with bushings as a bearing

and 2mm is nice !

thanks

[santhosh11dec]

A very gr8 work.......and how did u shape those blades so uniformly dude?

[19wael96]

time and being patient is the key !

plus using tools carefuly .

[santhosh11dec]

@19wael96 wat are all the tools u ve used??

[19wael96]

cutting compass ruler and scissors

[TheEmcol]

listen I do not want to offend you but to make a turbine blade you need a cnc machine to cut it for you mand they need to be to the mm. I am 13 almost 14 and i am buldin an afterburner and in my experience this is hard. The only thing different is i have the matierials.

[jojo240sx]

they like shit they will never work they are too flimsy and would blow up in your face!

[samuelm77]

how did you make that

[19wael96]

just replicate it on paper using a ruler and a compass

then replicate it again on aluminum sheet or metal sheet

forget the other reply thanks

[samuelm77]

@19wael96 im just 14 i dont have all of those utilities

[19wael96]

i am just 13 and i get my metal sheet from a soup can or any tin can

[samuelm77]

@19wael96 oh thats smart kid thanks chek out my vids

[vlinderbom2]

@19wael96 are you seriusly 13

[19wael96]

yep its true

[vlinderbom2]

@19wael96 nice i am 16. how do you cut the metal i use a dremel to olmost cut anything lol

[19wael96]

i use scissors to cut metal or aluminium sheet like 0.5mm or 1.0mm thick

because it is cleaner than spinning cutting wheels .

[Domynyck17]

З якого металу-це зроблено??

[19wael96]

Я зробив ці турбіни

тільки метал від металевих ящиків

[Domynyck17]

Добре,доволі креативно(kreativ)

[19wael96]

Спасибо

Якщо ви хочете використовувати цей дизайн зробити свій власний турбін

[Domynyck17]

Так я хочу зробити свою турбіну,але я мало ,що про турбіни знаю,тому хочу переглянути інші ідеї і зробити турбіну!!

[19wael96]

шукати в Інтернеті та переглядати відеозаписи на

пізніше я збираюся поставити ще одне відео про турбінах

[Domynyck17]

Я прочитав деяку літературу про тупбіни,та на відео їхнє практичне застосування,хочу перейняти у вас деякий досвід!!!Я підписався на ваші відео буду чекати.

[19wael96]

Я розумію,

[superfunnyman123]

nice im going to take a go at making the compressor for the soup can jet out of steel sheet. the allu. keeps melting on me.

[19wael96]

good

i used aluminium for the front turbines

and steel for the back turbine that comes after the combustion chamber

you can use my design of turbines they dont require welding .

[JetAce08]

nice, came out better then mine did lol
