Model Turbine Afterburner Testing 2

[@HellTriX]

Now need to add water injection into the afterburner to add some more thrust and help drive temps down :D

[@DirtNastyCivilian]

I myself was curious what turbine temps were looking like.

[@Mr3Kidneys]

Good god, man! This is insanely awesome! Most model turbine afterburners I've seen were more for looks than anything, but the thrust on yours is obviously VERY significant. It's kicking the rig like crazy! You can tell by the color of the flame that it's pretty efficient also, very impressive guys. Hope you can manage to actually put it in a model and fly it! Have you actually measured the thrust? I'd like to know. Full-size afterburning turbines approach double thrust, it looks like yours might surpass that! I don't know all the science of it, but perhaps the small scale could be working in your favor.

[@pauljs75]

Nice to see it kicking the test stand a bit, this one looks like more go than show.

[@knobby4]

Absolutely brilliant guys... well done...!! Makes mine look rather prehistoric, mine is just a a simple setup with manually operated pumps and valves.. I'm in Sydney BTW.. Cheers, Smithy.

[@balleRBLX]

Amazing! I haven't seen one that could sustain combustion of the afterburner before. Have you done a thrust test with and without the afterburner section?

[@antonyarnanova]

Making the old man proud clint- I want to see them in the Mig- tokies 2015! Bam

[@JoshuaRinaldi]

01:13 outstanding masterpiece nice work guyshow... how much kilo of the thrust ?

[@claudedestquentin3138]

Le bruit de la PC est déjà là, SUPER!! ;-) Peut être arriverez vous aux anneaux MAC!?

[@arielwollinger]

oh my god, the thrust in that thing is insane!!!!!!! Amazing!! How about using EDF to pump cool air around the afterburner, using a second layer of metal? That could insulate some of the heat from the craft's body.

[@trevoncowen9198]

Ariel Wollinger why not get a turbo fan kit and slap it on there

[@muzzaball]

The fuse is gunna need some wicked heat shielding to survive those AB casing temps! Is that Inconel? The temps are fierce. Have you measured the thrust increase with the AB attached?

[@davidroberts1852]

That's how hot my PC runs when I max graphic settings.

[@bmw328igearhead]

Hahahaha my processor glows like that for minecraft at 800x600 and zero mipmaps.

[@HaiderAli-qz1kz]

that was awesome. but how much power it gives? kindly give me detail.

[@Mike-01234]

I have been very surprised that no one has already marketed a after-burning RC jet engine, but I figure the challenges are fuel consumption.

[@HarvickOne]

you can probably send a well designed drone to supersonic speed with that thing, impressive construction and performance

[@BillyReed68]

I know this is an old video but, you really need to expand that nozzle or you are going to damage that turbine. Also, compressed air injection cowling to keep those exterior temps down?

[@nutsackmania]

its fine dude chill the fuck out

[@TheCraftedMine]

This is incredible, any idea on the amount of thrust? I had the idea to build a larger engine like this to put into a full-scale replica Me-163

[@chiaweichang8604]

Wandering know how much thrust was increased when the afterburner on?

[@yongmoonwon3223]

What did you use for the turbine blades? I'm in drafting a design, maybe I can get some ideas from you.

[@moniker_alpha513]

likely a titanium alloy of some sort

[@klab3929]

Probaly titanium since it has higher melting points and lighter than steel

[@roguepathfinder2477]

Try to use inconel or incolloy. They are very high temperature resistant, cheap nickel alloys, and are made for turbines. This is what car turbocharger turbines are made of.

[@marckerger]

Cool. How much more thrust does the afterburner bring?

[@hd13402000]

I am extremely interested in the afterburner set up and what like to know you did to be able to turn it on and off with with your remote

[@clintontrex]

It’s microprocessor controlled, reads off a spare channel on the rx from a toggle switch on the tx. Check my video afterburner display unit

[@hd13402000]

@@clintontrex im all new to this but any info /parts info you could give me would be very much appreciated im building a little project for and just looking for afterburner more for the look...i eant it to operate and all but not to worried about achieving the most thrust I can get out of it just looking to be able to fire jet up and be able to do a few burner pops...my next project will be mor serious but for now just looking for the cool factor im building a bicycle with a jet on it and would be cool if I can figure out how to make a afterburner I can do alk the welding and fab work im just not sure on a fuel nozzle and how to operate a fuel supply and shutoff valve to be able to do short burst of fuel for a burner pop

[@ethanzarian3163]

Good work guys I just want to know where I can get the plans to make one of these for myself I'm really just starting off on this hubby and I really really want to be able to put this on mine whenever I finally get around to building it are there any kinds of instructions to how y'all did this so I can make one for mine

[@mhmadkrdo1797]

Please how many revolutions are appropriate to operate a jet engine

[@thefrenchgamer7727]

at 9:00 the table was about to take off xD

[@chippyjohn1]

why didn't you monitor the thrust and display it, would be awesome, but nice build. the turbine is just store bought is it? You fellas are Aussie or Kiwi, nice.

[@QAT4969]

this will look sureal when slapped on to blackbird RC. what are the numbers guys, when at; 1. 90% throttle w/o AB 2. 90% throttle with AB

[@tech4pros1]

or an English electric lightning.. or four of them on a concorde..

[@QAT4969]

@@tech4pros1 that will propel that RC Concorde to 500km/h maybe. need to redesign its structure to have better rigidity

[@GRANDSYSTEMcoltd]

Very nice work!　want to see the internal structure. Are you using the spark plug is in the ignition ?

[@georgerickard5509]

GRANDSYSTEM co.,ltd I also want to know this. It's a spark in large (military) reheaters, but assuming this is running on kero, a glowplug should do. I'd also like to see the flame holder.

[@zenpro8164]

on your AB did you use a fuel tube or injectors? spark plug or glow plug? Im just trying to get ideas when I put mine together..super thanks 😃

[@clintontrex]

zen pro it uses an injector ring 50mm ahead of the flame holder. For the ignitor I used a hot streak setup which I built into the turbine this runs for 0.2s. At the same time the afterburner pumps start. It's all programmed by a homemade hand held unit. My friend is standing ahead of the afterburner watching a display which adjusts the hotstreak time hotstreak power and afterburner pump power.

[@zenpro8164]

clintontrex ok super thanks 😃

[@mariusfrost640]

Were you ever able to measure the additional thrust?

[@johnbravo7542]

Did you guys make the turbine jet engine and the afterburner part thingy ;-) well done.

[@jonjo2598]

What materials are you using in your design by-the-way? You look to be within a hairsbreadth from reaching the melting point of AL., are you using TI?

[@clintontrex]

Hi, the AB is all high temp SS, in this run the EGT at the rear of the AB got to 1140C, will have an boundary layer system next

[@richardkautz2947]

Someone's just got to mount that on an RC jet and let it rip !

[@DumbledoreMcCracken]

Did you shed any turbine blades?

[@Mad_gamers323]

How much thrust did you get out of it?

[@jonjo2598]

Have you guys considered a variable nozzle? I saw the heat spreading up your reaction chamber and though I doubt the flame is hot enough to melt your nozzle the buildup of pressure could lead to some problems. A simple solution can be found in the video below. variable nozzle www.airspacemag.com/flight-today/how-things-work-afterburners-18481403/?no-ist=&page=1

[@Kal-0000]

That looks a lot better

[@pereldh5741]

Great work lads!!

[@donovanr8919]

Hi. What materials are you using in your design???

[@clintontrex]

Hi, the sections are made using locally available SS316 which is just 3 and 4 inch tube with reducers for the diffuser and nozzle, the flame holder I used SS253ma because it is very thin, everything is tig welded. The rings you can see are 12 bolt flanges so different parts can be swapped out.

[@zippy3711]

I hope this is going into a RC jet. you gotta bring it to the New England Jet Rally !

[@clintontrex]

Yes the plan is to mount it in a model jet. I bought a FeiBao Mirage F1 with the intention of mounting this engine in it however the kit is really small and only holds 3L of kero. Just waiting on a suitable air frame now.

[@michaelsarysz1969]

clintontrex we have your airframe -facebook.com/groups/Minnesota.Lancer/?ref=share

[@57lexus]

That A/B gets to hot to install into a model jet airframe.

[@geekybench]

Your neighbours must be happy :)

[@carmelpule6954]

Excellent design, but some safety is suggested and that fuel should be out of the shed not on the table. Perhaps some bypass air should be bled to cool that afterburner as it will not work ccntinuously.

[@zenpro8164]

how do you figure out the exhaust hole size of the afterburner tube

[@clintontrex]

zen pro I just sourced standard sizes from a local SS supplier, the chamber is just 4inch and the nozzle is a 4inch to 3inch reducer, the chamber is twice the length of the diameter so 8inches. There was no calculation and by no means is it perfect or correct, this AB was built purely for fun. The flame holder is the critical piece. Ideally the nozzle should be variable to adjust the pressure in the chamber and gas speed, check a vid of a fighter e.g. F16 takeoff from behind and you will see the nozzle actuating.

[@zenpro8164]

clintontrex ok super thanks much appreciated 😃

[@anakmumama]

How much added thrust?

[@chiaweichang8604]

Hamdan Md Ali so do I! Wandering know how much thrust when ab on!

[@klab3929]

They didnt make the engine, they just put or made a afterburner for it

[@southernwulf530]

Hmm five gallons every ten minutes
