first of all, u need to add (fuel pumped in 1 sec *energy density of the fuel/sec) to get watts/g for the EDF + burner. you can easily upgrade your setup if u can find a clever way to compress the air, good luck and keep posting because not many people doing such stuff, it is great help.
This is super cool! I recently have been interested in this for rc jets and it seems there are one or 2 people who have already done quite a bit of work in the rc afterburner field! Really like your videos!
Thanks. U are doing exactly what I plan to do. If you can have a smaller sealed exit tube( reduce pressure leak) , i am certain the afterburner can generate way more thrust.
Great work! I'm interested in building one of these and controlling it with an Arduino as a cool demonstration but am unsure what to use for an exhaust tube. I'm thinking to use brazed sheet steel, how did yours hold up to the heat?
Wouldn’t a smaller flame holder condense the flame and make it more stable I don’t know I’m just putting it out there and I can’t wait for this to fly some day and I will try it too. Probably…
@@WArbirdFan4FlyingMillionaires Around 7:16, the "pipe" or thrust tube is most likely what has to be made a certain way t get the most out of the expanding gas VID HERE - th-cam.com/video/mH3BBUpzj9c/w-d-xo.html
@@WArbirdFan4FlyingMillionaires If the tube length is correct (usually short) and you stay above 90% FSA exit diameter the fan doesn't stall relative to power input. The energy out of the fan is converted into faster airspeed that can be read by something like eagle tree pitot tube when the nozzle is necked down. From the video I posted looks like there's a CRAP TON of fuel thrown into the AB chamber to get the 50% more thrust. All the videos I see attempting to increase thrust they're just lighting the fuel and they don't increase the fuel like they do in a larger model
@@WArbirdFan4FlyingMillionaires Ah ... I had assumed that the afterburner you were using was aligned with the heat absorbent paint maybe multiple layers of it... Yeah that could be a problem. There is a way to 3D print a ceramic tube that with stands a lot of heat I will find the video for you
I don't get it. I saw 6 kg with just the edf, but only 200 grams with the burner. So the angle of the camera was hidding the dot.... Anyway this doesn't seem like and accurate test. You didn't even bother to design a good nozzle. What thrust do you expect from a piece of paper?! If you do it, do it pro, so I don't have to do it myself after loosing time with your video.

thank you, I'll definitely take that into account for the next version

most sheet metal should be able to handle the heat as long as it is not run for a long period of time.

I believe so, I may make a video on different size eflux rings and thrust tubes
@@JRYBuilds that would be some good scientific data

Max 3000g on the scale! Lol
10% is Great but.. would you be adding 10% more weight to a Craft to carry all this ??? great stuff tho i plan to build my own soon
Yes, these designs aren’t very efficient but more of a proof of concept. That is why I’m trying to build them out of carbon fiber to reduce weight
