I Bet I Can Turn a Fan Into a Jet Engine!

[js]

You were that kid in school who won the Science Fair every single year lol

[kaylor]

Wow, I didn't know This Old Tony showed you how to karate chop your metal stock in half. What a great skill

[mubinzombadkar]

I remember once a wise man said, *"A jet engine without self sustaining cycle is just like a fan with afterburners"*

You need a nozzle!
Heat makes gas molecules move faster randomly. A nozzle points the random motion in 1 direction, giving you useful thrust, but mismatching the outlet diameter will give pressure differences that lead to a loss of thrust.

Take a look at your video here where you see the exhaust from the outlet. The flame immediately expands. You can see the conic shape of the blue part of the flame as it leaves the tube. You have too much pressure at the outlet, so when the flame leaves, it immediately wants to get bigger. Therefore, to get the most thrust, you would want to make a nozzle that speeds up the flow (a constricting nozzle, like putting a thumb over a garden hose). The nozzle causes the pressure to be converted into velocity and therefore useful thrust. Try out a few nozzles with different inlet-to-outlet area ratios to see what gives you the most thrust!

(p.s. This is oversimplified, but should be directionally correct. You might also want a water jacket around the nozzle...you know...cus' you're throwing fire straight at it).

This is the best alabama engineering I've ever seen, he's even got a trusty piece of duck tape slapped on for good measure.

A jet engine uses a turbine to drive a compressor using the energy from the fuel alone. This uses a fan and electricity. This is an electric rocket.

Congrats on making a fan that blows fire

[implodingdragon]

That's really cool :)
I hope he doesn't mysteriously disappear ;)

Integza: Could I build this at home?
Scientists: Yes, but that's a very bad idea.
Integza: Cool, I'll 3D print that.
Scientists: *facepalm*

The thing about a jet engine is its self sustaining, so once the reaction starts and you get that flame. You don’t need to keep running a spark plug.

This isn't a jet engine. That's a flamethrower.

[sylfina]

i think this form was also used in flamethrowers aswell

[ZeL-iqsf]

Video idea- you should try making a valved pulsejet

[youngbloodbear]

You need a nozzle, not going to get significant additional thrust without any compression

[drewandrew]

I'm curious if you were able to get any thrust or what the difference in thrust between fuel and just air?

[Basement_CNC]

does it even produce thrust.... it looks like its just some fire in the wind of the edf

[Shadobannedlife]

You have some great ideas and some wonderful talent.
Hat's off to you Sir!🌞

Now you need a turbine fan at the output end, and a shaft forward ro the intake fan, then its a complete jet The electric fan starts it, and once jet is self running, the fan mitor functions as a generator, and the exhaust provides Add wings, and you have a jet aircraft.

This reminds me of that video Flite Test did a few years back. This is so badass!!
