Introduction: Turbine Engine

The Turbine engine is usually used in airplane .So regard as ordinary people ,maybe we couldn't have a way to

get in touch with the turbine engine.

But today ,I want to share a easy and accessible way which you can make a micro turine engine with yourself .

So ,let's go.

(p.s. I am a Chinese student ,so maybe I didn't express something correctly .If you have any step incomprehension ,you can give me a message . I will try my best to help you.)

)

Step 1: Turbine’s Principle

The basic operation of the gas turbine is similar to that of the steam
power plant except that air is used instead of water. Fresh atmospheric air flows through a compressor that brings it to higher pressure. Energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The turbine shaft work is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, so these have either a high temperature or a high velocity. The purpose of the gas turbine determines the design so that the most desirable energy form is maximized. Gas turbines are used to power aircraft, trains, ships, electrical generators, or even tanks.

The last photo is my engine design.

Step 2: Dismantling the Motor

First of all,you need have a electric motor like the first photo. You can find it from which like toy four-wheel drive vehicle or some other toys.

Then,you shuould take apart the motor like me. After that,you need to dismantle the copper wire from the motor.

And now ,you will have a motor rotor like the forth photo. You can see the 1.95mm centre bore silicon steel sheets which is we need.

Next,we need to take apart the silicon steel sheets from the disassembly motor.

you can use hammer or other tools to dismantle the silicon steel sheets

At last ,you should find a 1.98mm long bearing like the last photo

Step 3: Prepare Two Zip-tops

Next, you should prepare two zip-tops,and the one need a little big then the other in caliber like the first photo.

Then ,you need to scoop a little smaller hole than the small zip-top on the big zip-top like the second photo.

After that ,you need to clip the two can‘s top like the third photo.And you will have two zip-tops like the forth and fifth photo.

At last ,you should dig a small hole at the small can's button

The most inportant is that you should make sure the hole you scoop is a little smaller than the small zip-top to make sure the small zip-top can't fall down.But only a little small,because after we need to plug the small can into the hole.A little small in order to make sure after the two zip-tops can fit close together。

Step 4: Machining the Thin Copper Tube

Then you need a section of thin copper tube.The thin copper tube often used on fridge or air-conditioning(空调系统).

And you should seal one end of the thin copper tube by the screw like the third photo.

If possible ,you can seal one end by welding.

If you don't know how to do that,you can squash one end of the thin copper tube.I think ,it's simplest.

After that ,you can bend the thin copper tube into a circle like the forth photo.To make sure the circle is smaller than the smaller zip-top 's diameter.

At last ,you need dig some holes on the thin copper tube like the fifth photo

In the future ,we will use the thin copper tube circle to support the butane regard as the engine's fuel.

Step 5: Make Combustion Chamber

Now ,let's make our combustion chamber.

First,you should dig some hole on can's profile like the first photo,and you should make sure the thin copper tube circle can put in the can like the forth photo.

Step 6: Assemble Combustion Chamber

first of all ,Assemble the two cans like the first three photos.Insert the small can into the big can.

then,we should put the thin copper tube circle into the can

Adjust the two cans' position to make sure their fit well.

Step 7: Make Engine Impeller

first, we should cut 2 pieces of iron .The iron's diameter should a little small than your two can's Inside diameter.

then, you should nestle up the two iron to the paper.And ,you need draw the impeller lamina's drawing on the paper.

After that ,you need drill some hole on your impeller and dissect the iron follow what you draw.

Now ,you can use pliers to rotate your lamina with a suitable angle.And you have already make you impeller well.

At last ,you should dig a small hole to make sure the pontil can suitable pass through it well。

After ,we will use the silicon steel sheets to fixed the impeller on the pontil

Step 8: Assemble Engine

Now ,we should assemble our engine.

first,you should assemble the impeller(推动) on the pontil(铁棒), install a silicon steel sheets on both side of the impeller and weld them like the second photo.you should assemble the two impeller on one pontil.

I use the mash welder to welding the silicon steel sheets and the impeller.Because the silicon steel sheet fit the pontil well, we can fixed the impeller on the pontil well by welding the silicon steel sheets and the impeller。

When turbine working the temperature is very very high,so we should use the mash welder instead of useing the electric iron to weld them.

Then,you should slip the impeller into the combustion chamber,and you need use a silicon steel sheets to fix the impeller.

after that, you should use a steel bar to fix the other hand of the pontil to make sure the engineer lamina(叶片) can rotate well.

Now, you have already make your turbine engine.

Step 9: Let Your Engine Running

first of all ,the test is dangerous .So make sure the safe is the most inportant.

Then,Through butane into thethin copper tube,then use the lighter to light the fire .

And,you will see your engineer run more and more faster. You can control the ventilation quantity to adjust the enginner's speed.

I hope you can learn tubine engineer principle profound by making yourself engineer.

And you will enjoy the beautiful picture when your enginner running.

What did you use for the main shaft? Can it sustain itself without the air compressor blowing in the front?

The Electrobot (author)2015-08-05

Great engine build :) super simple design:) I very much like the way in which you created the turbine (impeller).

I do have some questions. Were the impeller and the silicon steel sheets from the motor spot welded together? How are the bearings attached? It appears to be welded together.

Is the shaft held by ball bearings? I once went to a huge bearing store and the smallest ball bearing they had was with an inner diameter of 3mm.

Was compressed air used to supply oxygen?

English is one of the most simplest languages. Much simpler than Chineese. Just keep using it and you will msater it.

PS: this is pretty dangerous stuff... Be careful and wear appropriate protection

english is actually a very complex language. it has germanic roots, greek, latin, and other roots, along with an entirely incomprehensible vocabulary of slang.

First of all,it's very dangerous ,so we must very caution。

I
use the mash welder to welding the silicon steel sheets and the
impeller。Because the silicon steel sheet fit the pontil well, we can
fixed the impeller on the pontil well by welding the silicon steel
sheets and the impeller。

Right,the shaft held by ball bearings, I use a 5mm one.

You can see my step1 ,the thin copper tube circle only use to support the butane regard as the fuel。

When turbine working the temperature is very very high,so we couldn't use the electric iron to weld them。

Well described - However a jet engine should produce thrust. As your cans are the same width throughout they won't produce thrust.

That makes this more of a blow lamp.

mosmond (author)rickharris2015-08-22

I thought the purpose of a turbine was simply to do work. Power is produced by the rotation of a shaft just like an internal combustion engine. The only difference is that the rotation is caused by a different process. Rocket engines, which produce thrust directly from combustion, are an entirely different concept, as far as I know. That's my understanding at least. But I am by no means an expert - only a curious dabbler. So please correct me if I'm wrong. :)

In other word, no thrust, no spin,

author
344185151 (author)XXXX32015-08-12

I have already upload some schematic diagram in my step1

It have thrust and spin,

author
XXXX3 (author)rickharris2015-08-04

If it were not producing thrust the turbine would not continue to turn.

Ah I seems you are confusing thrust with spinning. While a turbine engine does indeed produce thrust whilst turning, the act of turning does not indicate that it is producing thrust. Simply moving air from one side of the can through the body to the other side does not constitute as thrust. If there were a turbine to catch the hot gases and convert their lateral move by into radial mechanical energy to make the blades on the front spin faster then you would be producing a larger volume of gas flow. Whether it produces thrust or not is another topic entirely.

this is very cool, and your english is actually quite good. i have a qeustion sincse you are using aluminum cans, wouldd they eventually overheat and melt? or could you actually use this to maby just maybe power small plane?

author
SamirB2 (author)darkath2015-08-09

I dont think that this engine will be able to power a small aircraft.

author
344185151 (author)SamirB22015-08-10

You are right。 It only a small turbine model

author
stayputnik (author)darkath2015-08-09

These are probably steel cans, like the ones canned vegetables come in. These cans are glowing red when they're hot, which happens with steel but not with aluminum.

author
344185151 (author)darkath2015-08-05

No, The aluminum cans' melting point is high

super knex builder (author)2015-08-05

This is a pretty awesome build thanks for this man. From what I'm reading if I were to make the end the flame comes out of more cone shaped this would produce more thrust? I'm asking anyone here

author

Also would propane work as well as butane?

author

I would think so since both are fuels but there might be some modifications required then, I am not too sure, good luck :D

wingnutzster (author)2015-08-06

without a combustion chamber I don't understand where your thrust is coming from..is there any measurably thrust have you measured it? Forgive me if this was covered in previous posts - I don't see a coke can containing the kinds of combustion and pressures necessary for thrust - makes a great demonstrator though. Another issue is that the fans/impellers of any thrust producing motor need to balanced - it is highly critical for thrust to be produced - this is very much like a turbo - nice

I really like your engine! May you give me the height and the diameter of the cans you have used ? Thanks!

author
ArtB1 (author)MamaOmom2015-08-05

use a regular beer can and one of the skinny Coors cans(if they still make them)

author
344185151 (author)MamaOmom2015-08-03

Oh ,thank you,but I am in China .maybe you couldn't buy the same cans like me.

You as long as make sure the big can is bigger than the smaller one .

because you just make sure the air inlet is bigger than the air

author
Bverysharp (author)2015-08-05

Great build! What kind of welder did you use to weld the impellers to the shaft?

author
ArtB1 (author)Bverysharp2015-08-05

I would assume mash welder is a spot welder

author
344185151 (author)Bverysharp2015-08-05

I use the mash welder to welding the silicon steel sheets and the impeller。Because the silicon steel sheet fit the pontil well, we can fixed the impeller on the pontil well by welding the silicon steel sheets and the impeller。

When turbine working the temperature is very very high,so we couldn't use the electric iron to weld them

chromium (author)3441851512015-08-04

Why, that's great. But can you explain the structure of your turbine a little bit, I'm not quite understand how it works. Thanks!

author
344185151 (author)chromium2015-08-05

Oh, I have already improve and perfect it.

you can see the new step 1

Thank you for your advice

author

There is nothing wrong with that. They fact that you can speak English as well as your native tongue is a leap above the rest of America. Myself included.

rtoddhale (author)2015-08-04

Is this a self-sustaining turbine....or does it only "work" as long as air is forced in through the impeller as seen in your images with using your air compressor?

Todd

author
344185151 (author)rtoddhale2015-08-04

Oh,it is a self-sustaining turbine

Although it only a model and only make little thrust because of the friction,

It can work by itself
