Making an LTD stirling engine
This is a video explaining how I made my LTD (low temperature difference) stirling engine. I made the engine in the school workshop over the past couple of months. This is a really simple yet effective engine, that is supposed to run on the heat from your hand, but my engine requires about 40oC to get going. I got the plans for this engine off this website: heetgasmodelbouw.ridders.nu/Webpaginas/pagina_ltd_stirling_met_cds/cd_dstirling_frameset.htm

Making and firing black powder rockets
Просмотров 4,8 тыс.16 лет назад
Made a big collection of rockets for my brothers 21st. The big ones are the biggest I have ever made. They are all core burners.
You are a genius
Give me the rocket rocket powder black recipe for the fireworks
Hey bro the size of the nozzle determines the rocket blast or fly right
Hey mate, I'm trying to build this for my school proj as well, but I want to try and integrate an actual generator (coil and magnets). If you have any ideas as to how I could to that it'd be much appreciated. I also wanted to know if you managed to find out where else you can find perfectly circular glass, apart from the syringe (I was going to use a test tube myself until I saw this). Thanks for the video. -Will
The displacer piston moves the air, not the floating/sinking of air due to density. The expansion of hot air and contraction of cold air is what makes the engine turn.
The air is only moving due to the "displacer" displacing or moving it. The flywheel turns because of the pressure increase from heating gas in a sealed chamber. That's why volume study is critical to Stirling devolopment. This is actually Jan Ridders design. Google "jan riders engines"
Very good. Thanks
Охуеннно, когда у тебя есть всякие станки, типа токарного, фрезерного...
Heloo i have Q Can i use wood piston because i cant find a graphite one :(
o funcionamento eu vou ver o rendimento depois
muito bom ,muito bem costruido
Can you give me the steps and how many missiles are long, how wide, how stavljas clay, and how big the hole for the Jets?
Tak tak,exelentní video.Podrobně popsáno.Místo grafitu je možno použír teflon a jemu hodně podobný,stejně samomázný materiál Liten.
Yes you can. Just change the phase from 90 to 270 degree.
Just a suggestion on turning the top and bottom plates... you can use a ball bearing live center with a "bull nose" or flat nose. face off a piece of steel in the chuck and press the plate tight in between with the tail stock to pressure drive it. This would make it much easier to round up the plates. Good job figuring out material and fitting issues along the way,
To dig the hole should be all to costsame, and also - I think there could lead to creating a vulcano, But there are places where they use it becaus it it is not as deep to the lava . Iceland is one example.
As it runs on a temparature difference, then i expect the heat source to be the carpet on the floor. It should be warmer than the air.
Yes, in fact switching the sides makes it go backwards.
I want to build a big Stirling engine of some sort, where to find plans online?
maybe ruby bearings... they're cheap.
in your language I think are called "convection currents" that is the key, in English I can not explain more.
you are from England?
what lathe are you using ? what size lathe ? and how much did it cost ? :)
yes.. and that way u can use the solar energy.. it's done in the same way u can find it easily online
PYRONUBBY YEA!!!
Wow. Kom je uit Engeland ofzo? Toppie accent. :) Is al dat gereedschap van jou? Draaibank en freesbank hoorde ik ook voorbij komen volgens mij? super werk heur!!!! :)
yes
Wow, very nice step by step.
I've noticed that most stirlig engines are made with a heat source at the bottom and a cooling source on top, can it be reversed with a heat source on top and the bottom laying on a cooler surface?
I'm from across the pond, man...and this video is very,very nice! I've never heard of one of these types of engines! Greeting from america, my wise friend!
It's oh so easy when you have the money and tools..
can a aluminium displacer work?
@SwarthySkinnedOne it uses external heat to create a air pressure diference in the piston. look up stirling engine on wikipedia for the concept this is a low temperature variation.
what size nozzle do you make as in the hole thnx
Excellent video! I think all graphite parts can be replaced with metal ones, and the graphite could serve as a lubricant. All you need is to use soft pencil (2B, 4B) and fully cover the cylinders from inside, pistons and all other parts where friction occurs. If somebody is willing to test this please share your results. It could cause the necessity to repeat the graphite cover from time to time, while original solution is permanent, but probably more difficult to complete.
Excellent craftsmanship! Hats off to you and 2 thumbs up! I hope you are continuing your interests in this area and I wish you the very best of good fortune in it.
This is just excellent! Seeing that the graphite is hard to come by but needed to help with friction, have you considered maybe a white metal alloy of possibly tin and lead, since they are readily available? Or possibly some other common alloy of white metals that would be somewhat of a lubricant?
thanx god
Really Excellent video and commentary Never seen nor heard of anything like this till now i totally agree please more vedios and i wish you the best Thank you
Never seen nor heard of anything like this till now. Why does it do what it does, this Whachamacallit engine? No batteries, no gasoline? How does it operate without electricity or some kind of combustion process. How them pittles go up and down making the circuloptic spin? I mean what is the underlying principle? Looked very involved, like you had to go through hell and high water in building this little dooglewiggie-wombat-wipplepuppy & make the coloumbs in the air spin out frm rotationals SX.
Very well done. And THANK YOU for not carping on about "free energy from the miraculous Stirling Engine." You would not believe the idiots on RUclips who somehow managed to build one but don't know one of the fundamental laws of Thermodynamics...
where are you from? That's an accent i can't distinguish
Very concise. Nice video
First I was like, "oh what an elegant design" then I noticed it was just on the ground with no heat source "aww shit"
"coneected"
Excellent job in nutting it out, making up the parts and doing a great commentary video. I am sure you will go on to great things. We have some massive problems with the world economy at the moment, what about nutting out something that will fix that too :) All the best.
Its the best tutorial. Thank you very much.
excellent! the cometary is perfect! greetings from Germany
Really good video, thanks.
best video
