WHAT ELSE CAN A JET ENGINE AFTERBURNER DO?!

Today we show you our new jet engine design using a new afterburner setup. We start with how you can build it yourself and then run through some demos. We end with a fun show of fog juice (glycerin) running through the turbojet to create huge clouds of smoke.

Years ago, one of the first projects I worked on as an aerospace engineer was "Alternative fuels". We took a stock jet engine (as would be found on a light commuter jet) and ran everything from peanut oil to vodka through it. Turns out, the peanut oil ran the engine just fine, but to get it to run on vodka, we had to make modifications to the engine's software. Turns out, peanut oil is more expensive than jet fuel, but it has the added benefit of making the entire test site smell like fried chicken right after start up and shutdown.

You need a secondary ignition in Afterburner for a few reasons, Mixture Pressure, Temperature, time of atomization, and the cooling dynamics of the fluid as it makes it's way out of the nozzle. but when the burnfront is behind the ignitable gases moving at that speed with a soft even molecular cushion, you need a nice sharp spark to break that balloon. and that assuming you have some nice pockets at the injectors to stir things up, I find if you ramp up the fuel pressure nice and high with small nozzles it works well. the algorithm gods apparently know what I'm working on right now...whoa .. haha.

Exotic speakers, Fancy laser displays, now the mother of all fog machines... If they guy ever opens a night club it's going to be epic!

I've had a pretty awful day filled with 4 separate engineering job rejection emails, but this cheered me right the heck back up. You're the coolest internet uncle around lol

[bwobbles]

“I love my job” was so sincere. I am jealous of your amazing work and the fun you have, at least I can experience it vicariously by watching your videos. I hope you continue this for many years to come!

Neighbors, seeing cloud of fog:

"He's at it again."
"What's he doing this time?"
"I think... I think he's building a thunderstorm."

i dont even know how can someone criticize you man, you're the best teacher ever!

[Kabluey]

I love it. The genuine joy on your face when the fog burner was running is heartwarming. Great build. Love the whole thing

You are quite literally a cooler and more legal Mr. White. 10/10 quality videos

[carlmclelland]

WHEW, you were way beyond my paygrade, but I sat glued to the computer watching this. Thank you, sir, for a MOST INTERESTING education!!!

Every time you release a video, I'm notified 7 to 10 hours later because of time difference zone, so it's in morning time at work, I impatiently look for a peace time to watch and got drown in extreme pleasure by your nice and easy to understand explanation of each and every science and engineering points.

You are a great teacher, best wishes for you and your family from Iran.

Finally, a person that can explain this so even a dummy like me can understand ! Now I get I'm loving every minute of it ! Thank you

24:18 Stage one exhaust gasses have plenty of CO2 and NOx which are really good at absorbing heat and not giving it to the cold fuel. The way to auto-ignite is to pre-heat the fuel.
Run it through a pipe wrapped around the exaust and pre-heat it(it doubles as protection for the pipe)

I can't believe that I'm watching a video that opens with asking if you happen to have a turbo jet. I love this channel. Great vids. Keep them coming.

It's great seeing something being constructed from theory and in the process, overcoming the constraints that a practical, working model presents. Very informative and cool!

[totherarf]

My favourite moment of this one was watching you walk back through the fog trailing your own wake!
Got to say I Love watching you love your job!

Lower oxygen content in the gases after the turbine seem to be a reasonable explaination for an increased temperature for self ignition. Additionally, evaporating the fuel in the afterburner requires energy, which is taken from the turbine exhaust gases. Hence the temperature of those exhaust gases might be decreased significantly, depending on the amount of fuel added. Both effects together might be enough to prevent autoignition...

Other engineering videos: "Don't try this at home."
Tech Ingredients: "I'm gonna give you the plans, tell you where to get the parts, and give you some cool ideas. Have fun."❤

Back when I worked as ground-crew on the F-16 fighter-jet, we learned that the afterburner basically doubled the thrust at the cost of _quadrupling_ fuel-consumption.. So if the F-16 were to run on afterburner all the time, it would have enough fuel for ~15 minutes of flight... (That's probably with internal tanks only.)

I love how your assistants shirt is waving in the exhaust winds.
Your channel is so cool. Great job. You make hours of content feel like seconds because i enjoy it so much. Thanks a lot.
