You can cut weight of Sprite leaving batteries out. Take power from AC, convert it to DC and put a cable to Sprite.
Awesome stuff! Does Sprite require any yaw correction for the acceleration of the EDF blade? If so, how does it do so?
Heading to Patreon now!
Now, grab a oxygen can, dump the butane + oxygen in a nozzle, and… We’ll see what will happen.
you have the slightest resemblance of Elon Musket
Was NOT expecting to see the afterburner so early on in the video. I loved it.
Soooooo Sprite is now an expander cycle? I fn love it.
singlecopter mode? during test the parts are melting, perhaps print those parts in alu? great job;)
Sooo cool. Totally pointless. Afterburner needs a column to contain expansion and increase thrust, this is more like a dump and burn but soooo cool.
Have you considering applying the Bernoulli concepts to the ducted fan to increase thrust…or are the flow speeds to low to actually make a difference??
You look like elon musk.. Hit like if someone else agree with me
No matter how useless, if it looks awesome, just do it
Here comes Charlie Garcia doing some crazy maths on nozzle shape and fuel injector :))
Hey I also built a EDF AFTERBURNER in my bed room
I think you need to atomize the Buthane with a fine nozzle. The increased survace area will help with a more stable combustion.
But i guess you had the same idear with the copper coils.🤗
this should be used to deliver packages
1:16 I really thought you were going to say Raid Shadow Legends.
You could try cutting little tabs into the rim of the combustion area, then give them all a little twist to create turbulators. This may help with the mixing. Nice EDF BTW. I have two and they are beautiful beasts.
Did someone also get a lot of Dyson adds during this video 😁
Does the afterburner actually add thrust or is it just to look cool? It looks awesome by the way.
I suggest built a big rocket and went to moon
Love your vids. Sprite is pretty amazing, reminds me of the Missile Defense Mutiple Kill Vehicle (MKV-L).
Love what you are doing, I told my son how cool will it be when someone actually makes a real working rocket engine. His reply was it’s to complicated, mine was you have guys in home shops making turbines.
8:30 in – looks like Sprite isn’t completely symmetric or properly balanced.
He can’t grow hair? Or does he choose to look gay
1000% cooler than the edf
Mix with air and use a simple one-way valve and a Y splitter on the hose.
Before they were famous – Elon Musk
needs more liquid oxygen
Guy looks like Elon Musk + Mark Zuckerberg
wouldn’t it be easier to just build a bi-propellant liquid engine?
11:10 I’m sure you’re know what you’re doing, but from the test footage it looks like you don’t have your coils heated sufficiently(as you noted) before increasing airflow. With white gas stoves the fuel is usually burned in a reservoir to heat the coils before introducing more fuel. Consider limiting the butane input on startup and allowing time for the coils to come up to temperature.
no need to explain yourself… we like fire
Would using an aerospike design be more efficient than using a bell-nozzle design?
Have you considered adding a second counter-rotating edf or switching to a double-prop design?
Can you add a de Lavel nozzle so the fire really looks like a rocket engine?
“What is this? Some kind of plastic ice-cream scoop?” -Harry Stamper
It’s cool that super-heating your propellant is trivial to someone inclined at this scale.
Vat vas dat? fthrust chamba instabiliti? auhhahauha…
When the engine is starting, i can see a lot of liquid butane going out of it, i think you could have a better air-gas mixing (so a kicker and more homogenous combustion) if you directly inject gas rather than liquid that takes time to evaporate and burn. To do this you could flip over your gas tank so gas will go out before liquid or maybe use propane that gasifie kicker than butan do to his higher saturated vapor pressure.
Need to change “Afterburner Ignition” to “Activate Yeet”.
use the head off a cheap propane torch.
Nah, you’re using fancy tape, respect retained!
I wonder if an atomizer coil could improve the combustion? Like in a vape device.
With the butane afterburner, why not have the can in the upright position, that way it sends more gas than liquid. I would also recommend some sort of spray nozzle to give a better flame.
Reminds me of the Palomino.
7:39 if the edges from the top of thw rocket to the top of the EDF were smoothe all around the inside edges the intake would be less turbulant
This was awesome filmmaking!
0:55 when you build a hyper complex fan powered hopper with afterburner and dual band GPS, just to clip your mic to it
EDIT: Just use some gaffer and some parts from RIPed mic stands like everyone of us sound engineers do. And don’t forget to NEVER EVER match the mic brand to the brand written on the mic clip
That looks like the same leatherman supertool i’ve had for the past 20 years!
you convinced me to apply for phd studies. love from morocco
That is some dilated pupils right there.
Check out the FliteTest’s afterburner video, the engine part is kind of the same.
Too much fuel, even before shutdown it was still dripping.
Hey SpaceX hire him for miniuatre rockets for demonstration of Mars landing this guy will rock it.he rejected SpaceX offer I know
!rip already melting vector fins
Daaah, that’s hot, that’s hot.
When u getting job at spaceX? 😂 you deserve it!
“It’s better to look good than to feel good, darling.” – Fernando SNL You are so right, Joe. Sometimes the cool factor just wins out over practicality. I am ashamed to say I have also flown some sketchy aircraft in sketchy conditions only for the hope and gamble of some great usable video. Keep up the cool factor…
Try an aerospike even though it’s not the best option in the long term!
audentis Fortuna iuvat my friend, if you know what I’m sayin’
solid motor igniter wouldn’t ignite the butane? Atomize the fuel, add some peroxide..
Starship model and propulsive landing 2nd stage
I don’t now anything but how about mixing oxygen with the butane from an acetylene torch? You can very the amounts of fuel versus oxygen to keep the flame lit.
That thing is way to heavy!
Man I love that NASA sweatshirt at 6:48 looks awesome!
I swear the god I will like this comment.
(Now you have to realy like it :D)
Combustion Instability: If they can solve it in the Mighty F1, you can solve it for Sprite.
Looks like ‘flame lift’ in gasman terms, 40% or more thrust exceeds the speed of the flame burn.
Perhaps a lower speed air flow chamber in the centre?
Better oxygen/gas mixing in the chamber (bit like how the air comes in low on a Bunsen burner – might be more blue flamey than yellow) then igniting in the low speed area and then properly expanding/burning in the high speed airflow area.
Why don’t you build a jet engine with oxygen sprayed into
I was exclusively watching those little fins melt during the test.
Be careful with those winds below around an open flame
I appreciate the added thrust😂😂
But seriously trying dumping some NO2, or just straight O2 through the stators before it hits the butane for some extra kick.
Instead if Aluminum Tape – Why not use Steel Foil?
Testing when the craft is on a flat surface will disrupt the air flow
looks like FliteTest’s afterburner, with 1000% more complicated engineering!
Weird question but when you speak about working on your aircraft you always say “we”.
Love your work just wondering if you work with yourself or with someone.
Edit: this is a serious question. I presume he says “we” because people also help in the community and also like someone said in science reports they never say ‘I’.
I can’t wait to see this fly
My respect for you as an engineer has actually increased because you admitted that the afterburner is just for looks
I enjoyed the “visual effect” way to much haha
Just my 2 cents:
1) run a coil of copper tube in the exhaust before combusting the butane. It’ll vaporise it and give you less fuel consumption and a cleaner burn.
2) keep the low pressure zone you’ve got the same, but make sure you have some air inlet holes at the top as you need the fuel to combust in the zone which will require airflow. If the hole’s too big it’ll blow it out.
3) look at David Windestal, he made one for edf. Seemed to work quite well.
Turning the butane bottle around could help to get only Gas out
Use a perforated ring like the one used in tc jet turbines and for the nozzle do a closed cone with holes to create a Venturi effect.
I’m not an engineer nor I’m studying to become one at the moment, but: what if you constrict the primary flow around the low-pressure-creator? In other words: you should try to put the low-pressure-creator inside the tube, and not just after the edge.
Edit: you probably already know this channel (which BTW is a great channel, check it out everybody), but here’s a playlist that may interest you
BPS.space: Instead of building a complicated setup yourself and trying to debug it, you could use the business end of a soldering lamp. This also usually comes with a build in regulator as well as ignition wires.
No, no, no. If it doesn’t produce thrust, then it is useless – get rid of it.
Looks amazing. Would recommend the flite test video on a afterburner similar to this
I love it. Atmospheric Rocket engines could be built like it.
Hey Joe, i hot 2 questions. How long does it take to preform an “echo” test and when can we expect the next one. No rush just curious.
Looks like a chrismas tree with legs.
He looks like he hasn’t slept for 3 weeks. Get some shut-eye!
This guy literally looks like elon musk
4:29- nonononononono you just need MOAR BOOSTERS
Aww. He’s following in the footsteps of his father!
no matter what your level of professionalism or education we ALL love to see some controlled exothermic reactions! Love me some blue diamonds.
You look like a younger and skinnier version of Elon.
“I really love fire” says the guy with flowers and doves on his shirt
LOL the sponsor bit, I was like oh god no not raid shadow legends, brilliant, or skillshare.
2:37 every kid on xbox 360 with a walmart mic
Edit: Okay… Didn’t expect so many people to like my comment. Thank you guys!
*Seeing the ignition test
“Sweet, I wonder how much extra thrust it prov-”
“It’s mostly just for looks…”
Notification squad! Excited to see what the heck this thing is 😱
