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.
