3D Printed Compressed Air Radial Engine

ah yes, using air to power an engine to turn a propeller to move air.

That honestly sounds a lot like a real radial engine... My family owns a Cessna 195, and this has an insane resemblance of our airplane at ~2500 rpm on takeoff! It’s amazing how such a similar sound comes from a model of that size.

Awesome video! I know what I’m printing next! 😉

no matter the size the material and the shape, as long as its a radial engine it will sound just like one

This is fricken amazing!!! Wanna see more🔥

Nothing new Ukrainian Antonov bureau made 32 jet engines using compressed air. A engineer from Antonov took the concept and placed in a Volga car body in 1986 and Gorbachev drove it and suddenly stopped asking the inventor what are running this car on he replied air . Gorbachev said we spent billions of dollars in Siberia on oil and gas ventures disallowed the invention but the engineer won a medal .

You should rly have more subs. . . I'm subscribing, hope it helps!

What if you could recycle the exhaust air and dump it back into the compressed air canister?

Folks it is a real radial engine. That's like saying that diesel over there sounds like a real engine.

That engine looks like a shvetsov m-11

I'm really wondering, how close would it sound to an Inline-5 without this propeller.

Any idea on how much power that thing is putting out?

i want to make some air engines sometime

Mine works too. I printed it and after a bit of finishing I did it, I mounted it and it worked. The problem is that it requires a lot of air to spin at a very low rpm, it doesn't reach the speed it reaches in the video. It seems that when I introduce the air flow it tends to slow down. I have two questions. The first is that the rotary valve that you put among the files to print is present both in the pre-assembled engine in step format and in stl. Which one should I print? The second. How precise do the pistons have to be? If I make them more precise they slide worse but push more, but the engine doesn't spin very freely due to the friction between the cylinder and the pistons. If I make them less precise, the engine spins freely and smoothly. The problem is that the pistons don't push because air passes through between the cylinder and the piston, so I don't know what to do.

Does it blow more air than pointing the air line at your face? Or is this part of the law of diminishing returns?

[ethanproctor]

Might be a big ask, but would you video how you make this kind of thing? Sort of like integza. I'll follow you and tell people about you if you're after that.

Se serait intéressant d y mettre un volant moteur avec des aimants permanents pour en faire une mini générateur, pour recharger un téléphone par exemple, et l on pomperait pour maintenir la pression de temps en temps.... J ai vu un système d un africain qu il avait construit mais avec une turbine c est genial
