Red hot glowing 16 Cylinder Stirling Engine

Here I show a 16 Cylinder butan powered Stirling Engine that I ordered from china.

Although it looks like an aircraft engine it is just a desktop toy. Stirling engines have a way to low power / weight ratio to be useful in (model) aviation applications.

What makes it special is its unconventional swashplate design
and its awesome jet engine look.

Lotsa pretty machine work, fun to watch it run. Pity there are always so many comments from "experts" who miss the point entirely and are probably challenged by driving a nail into a board.

8 burners, 8 pistons, 8 displacer pistons= 8 Cylinder Stirling. Interesting swash plate application in this 8 cylinder Stirling. Running without a proper flywheel is also unusual . Thanks for sharing.

Those linkages in the middle are painful.

Your videos are giving me a bit of a fascination with stirling engines!

[MarkLovesFly]

I find this surprisingly satisfying to watch!

[phildouglas]

Well done. I've only heard of Sterling engines. But now thanks to you I know how they work.
Good job!

Augh! The noise, the movement! I'm positive this is the kind of plane engine that HAyao Miyazaki dreams of in his sleep.

This is amazing
Just so utterly awesome you made this. I love creations that operate with very little input to them and they just work... It's beautiful and elegant

[omarmang]

Brilliant! Thank you for this amazing demonstration.Mechanical art at it's best

if the fan blades were bigger, it might cool the front down more, and that would give it more power, according to the principle it operates on. Then it would need a shield around the back cylinders, though, i think. And it sounds like it needs some grease, too.

Beautiful piece of art incredible craftsmanship

Do us a big favor and get a bunch of different angled propellers with the same mass and diameter. Build a stream tube for your engine, then measure the difference in speed at both ends. That way we can find it's power output at multiple different frequencies and map it to hopefully find it's maximum power output.

There is a way to improve the efficiency of this nice engine: The front "cool" cylinders are not within the propeller airstream.


One needs to change them by props with a much smaller hub so that cool air is really reaching these cylinders (they are currently resting in the wind shadow of the decorative nuts.


Efficiency of a Stirling engine is directly proportional to the temperature DIFFERENCE between both cylinders !

Coolest sterling engine I've ever seen.

could you please make a video that has a disassembly of that engine?

[mattbarr]

stirling engines are so fucking cool, I love that we use them in space too. NASA has a pretty neato stirling engine design!

[LeutrimJusufi]

Have you had any problems with it so far? And how often have you used it? Great video

[BluedoesMusic]

interesting. pretty unusual but nice design, might make it faster to use water on one side and have the flames in a sealed container (with a vent on one a side.)

[gyanendrabhattarai]

Stirling Engines are the most efficient engines, not poor.

[markiewodi]

Love it! Very cool! I’m checking out some more!
