1/5th scale jet dragster test with afterburner

[krishwarsha]

dam man it takes Gas really fast.

[JAYOcarlow]

i have just seen thses vids for the very first time...why is no one fuckin eating the road out of it..they are all standing still...where the vids to see how fast the go...that why im here anyway

[bferr1]

look at that thing suck fuel

[stevecraignet]

Don't watch the fuel consumption guys-- this is all about thrust. Period.

Notice how all the air in the garage gets sucked out when the AB is kicked in. THAT'S what I'm talking about! Woo Hoo!!

[MalliaCamilleri]

have you ever taught of thrust augumentation just to give it some more umph

[stevecraignet]

@MalliaCamilleri Um... not to put too fine a point on it... but... the afterburner IS the thrust augmentation, and it adds 30% more thrust to an already incredibly powerful powerplant.

Right Smithy? Just thinking out loud here...

[x0druid0x]

Im in the design stages of building my own RC Turbine. Can you tell me what brand Turbine you are using? I was looking at the Jet Cat P100. Do you have any recommendations on turbine selection? Any help would be greatly appreciated.

Thank you :)

[crazzylee]

@x0druid0x its a jet joe jr

[Rich77UK]

Watch the fuel go!

[route66rocks]

holy shit look at that feul~!

[osito010493]

DEAR SANTA....

[SebaPee]

OMG! look how that gas canister drains from that flame

[TheMoffBoy]

lol, when the afterburner kicks in it slurps the fuel up like fk man!!! glad my nitro engine aint like tht....cost a bomb tht would,..

[wpockl]

Awesome job knobby4 ! I love watching rc jets at the flying field, this is a whole different level. How do you stop it , does it have brakes like a jet?

[snoops1586]

i love how fast it eats the fuel every time he hit the after burner

[samhp84]

you see that fuel level drop, mad

[1945blackops]

look the fuel at 0:30 and 2:30

[crzygutrsnobrdr]

how much is a gallon of the fuel it runs off of????

[dilliot2k]

that fuel tank reminds me of my car when I drive it everyday

[scorpirus]

if you can afford a model like that you can probably afford the fuel to run it as well

[nyehnyi]

what purpose of the brick. are you worry for reverse thrust or what?

[knobby4]

@nyehnyi

No, not reverse thrust, the surface it was sitting on was sloping slightly, the brick just stopped it rolling backwards before I started the engine. I had a brick at the front to stop it taking off too..!

Smithy.

[dallasvanity]

imagine if u put this engine on a modle fighter jet ..... damn id love to see that

[anas5055]

very fast the fuel gone...u can see it

[AndrewJuggalo951]

Gas hog or not, still badass

[jhondogXD]

me voy a suscribir

megusto el video

[jhondogXD]

ese carro o como se llame gasta mucha gasolina sierto

[xoio]

Does the AB give much extra thrust, or is it mostly for show?

[knobby4]

@xoio

At full rpm it gives ~30% extra thrust.

Cheers,

Smithy.

[TUNEITTHENTALK]

@VirusOfCyrus and your hobby is so much better looking at boring videos so you can talk $#!7

[knobby4]

@VirusOfCyrus

If you don't like it, don't watch the video....simple. I'ts a toy....get over it.

Smithy.

[neeyotube]

Step 1: Start video.

Step 2: Not level of fuel tank.

Step 3: Jump to near the end of the video.

[dmonte012]

Easily one of the best videos on Youtube

[andy11894]

any one got the marshmallows

[probmxers13]

honey wheres the house

[hawaiiandragon76]

Did you make the afterburner yourself? That thing is SICK!!! An people the engine needs to warm up before you can use the afterburner. For those of you complaining about when the flames come out. Cant wait to see it run on a track.

[dachhh]

Can you make it drive forwards too?

[rmelz3456]

uses lots of gas :/

[planeking6]

sick.

[AlphaCueLater]

Look how fast the gas is going rediculous

[MrBohica1980]

Nice. Keep me posted on the progress of your project. Impressive.

[andgate2000]

doesnt half eat that fuel. !!!!!!!!!

[blakhawk636]

yo i notic that lil sucker is a mad gass gussler

[justforever96]

Afterburner uses many times more fuel than the jet itself on full throttle. Now think of a F-15 engine, burning 215lbs per minute/engine on full dry throttle...and then think of it on full wet (afterburner)! That's like 1000lbs per minute...for one engine. I figure an F-15 with 22,000lbs of fuel will run out in 11 minutes at full burner, compared to 51 minutes at full dry thrust (which still isn't much...that's why they cruise at partial power.

[justforever96]

@justforever96 BTW, JP-4 is about 6.84lbs/gallon...22,000lbs = 3,216gallons. 1,000lbs = 146.2gallons/minute/engine

[fourbypete]

Not real fuel efficient when you hit the afterburner.

[oxymoron55051]

Guys...it's the same as in 1/1 scale. These dragsters only shut off when the tank is empty. What you saw burning, the flames, was raw fuel being burned

[ultragaming1993]

wooow it is drinking much fuel!!! damn XD

[EndofDays213]

The gas was drained more than half

[xXCREEKSTARXx]

What do u guys think...power comes from the fuel so...GIVE IT MOOOOOOOORRRREEEEEEE POWER :D

nice dragster...mustve been really expensive right?

[EZ4U2Say11]

is it just me or does the fuel get burned very rapidly? it's a beast.

[Gary12194]

Its like a giant lighter lol



[tm46367]

it uses a lot of feul :)

[Zrojas99]

It would be funny as heck if that thing just all of a sudden went off while you were testing it like BOOM - looks - well, that thing is long gone, Whos up for pizza xD Nice vid dude.

[mrbillandshell]

WoW!! Aesome!! I thought my Nitro Truck burnt alot of fuel, But that isn't anything compaired to yours.

[Jussinhussi]

Hey, your fuel goes down after after burner, you dont got more.

[b101aa2]

you can see the fuel level get lower and lower and lower. hehe

[TheDmDark]

Holy Shit, you could win this race with this car!

[quartermilesmile]

i love this, what a beast!!

[lilceazy87]

that is amazing 2 thumbs up

[23456785246]

I would not like to be the one who has to pay for the fule for that lil devil mobile

[bennett1608]

does anybody notice that fuel in the plastic bottle getting drained like mad lol if you had one of these it would cost more to run than your car

[19megalomaniac85]

@bennett1608 i got a nitro rc also costs way more then my car

[x0druid0x]

@bennett1608 yeah Afterburners suck fuel like crazy, but does provide and good amount of extra thrust.

[trsummers]

That is awesome.... not just the fire show... but wactching those fuel lines jump and that tank getting lower and lower... a wonderful display!!!!!

[5swords3]

Put a sausage on the end of a stick then put it behind that thing, dayummm hot and toasty.

[puggster]

Pretty dam awesome, drinks fuel like a thirsty sponge lol dunno if that's backdraft but check the fuel lines move when the afterburner kicks in, I'm thinking this could be from suction created by the fuel system?

[yamahonkawazuki]

@puggster what i was thinking some hellacious going out flow

[BigMacBook1300]

Gas hog

[ArcadeGames]

Dang, that thing drinks more than a sailor at a bar during happy hour:)

[gillynator]

fire comes out a 0:45

[No1Richman]

You don't actually see flames till 0:44

[Eowen2006]

haha you can see it eatting the fuel away!!!

[nicp90]

use that as your pine wood derby

[themattsteelfan]

woo, watch the fule drop! lol

[Crookster100]

you can literally see the fuel level dropping

[rjuke6]

Wow 2:30 it uses half the bottle of fuel and like what the others say it's thirsty

[RyanShinoda101]

Chuck Norris is Strapped in the back of this dragster while being fed BeaNs by carfully trained iraqi insurgents wearing Hazmats suits... He's farting T_T

[BillyKidJoe1]

i like watching the fuel go down every time you use a/b

[tubata111]

hahah fuel iconomy like BMW :)



[maxmax67ful]

if that thing ever hit your toe dam!

[Thercflyer96]

Look at the fuel go down and down and down...!

[artyfly100]

@Thercflyer96 yeah it drinks like a sponge!

[yamahonkawazuki]

@Thercflyer96 holy sh*t you aint kiddin

[leonatack]

fully fuel use

[megaduce104]

you can tell that this engine uses alot of fuel. if you look at the fuel box, you can see the fuel down

[bikerboy674]

WOW, you can see the fuel level dropping....

Man that is sick (positive way)!!!

[ethownzbh]

by the time you actually started moving youd need to refill

[Cozmixcartoons]

Ive built alot of models over the years, but ive never seen anything like that! Pretty damn cool! Did you build it yourself? How did you actually make a working afterburner? Ide like to see it in action.

[jasonyeozhishen]

when you go to camp.. and was playing with your RC car.. you can BBQ too? thats cool. . :P

[psygn0sis]

Now everyone can see how much fuel is used during an afterburn. A LOT!!!

[RoboTekno]

It sure loves its fuel :P

[Alighierian]

thats some way to fire up your bbq

[jpatt1000]

That bottle of afterburner juice gets empty pretty quick! Very cool!

[kilziwalk]

i was laughing at that it just keeps dropping each time it comes on !!!

[73sebrougham]

Wow what a gas guzzler!

[Insane82chevy]

i love building stuff on a small scale and big scale theres no in between with me

[KDOG3889]

nice garage heater



[CTBTRIPPLE123]

wow i can see the fuel going down in the tank

[edawster]

I wanna see it move. Btw it's totally awsome!

[stupidplants]

propane A/B?

[knobby4]

@stupidplants

No, it uses Jet-A1 with a little turbine oil mixed in to lube the pump. I do use propane to help start the engine though.

[luciffer420]

@knobby4 lol you can watch the fuel can slowly get emptier as he uses the afterburner lol

[porousorifice]

Cool to see the fuel line shutter when A.B. kicks in!

nice work!

peace

[jwigiMT]

To vtwinmesa: You're right and wrong on that statement. Yes a turbo fan engine provides a fresh air flow. However none of the after-burning engines are ever turbo fan. They are turbo jet. Jet engines yes produce a lot of exhaust and are serious consumers of fuel, but they only burn 25% of the volume of air entering the combustion chamber. A lot of that air is for cooling. After burners just utilized the left over air and use it for another combustion stage.

[FuriousVigor]

great job!

[kms7852]

start at 0:40 if you want to see flames

[bismillahmashallah]

lmfao 0:45-0:50 fuel jumps down loll

[patrofutbol]

deberia de moverseno creen?

mucho fuego pero no se mueve

[netmatrix75]

Did u guys notice how fast the fuel in the jar goes down if the afterburners is used?

[Jimmbo102]

if u ever need to warm up ur garage there u go

[np151]

lmfao look at the gas everytime he lets it go

[fluentinsilence]

It's funny watching it drink the fuel so quickly when the afterburner fires.

[ricardhoamorim]

when the afterburner start, the fuel of galon disappears

[Blackarrow8918]

uses too much fuel

[28Jimbobf]

Oh man thats ace

[ryancarter123]

look at the fuel just drop

[spcoulson]

hahaha u can actually see the fuel drain!! Holy shit

[BioHazrd07]

Wow look how fast it drinks fuel

[edj66]

God it sucks that fuel away doesn't it!

[tjkringayark]

I can see the fuel is running out FAST even with the small scale size.

[offspringfanman96]

holy crap look at all the fuel the afterburner consumes!

[antonisbob]

is that thing beside it the fuel? LOL you can see it gonig down in real time xD Awesome!

[123Mrhondaboy]

that thing eats gas

[UptownCarwashBoy]

i loved watching the fuel dwendle

[CRUNKshaft]

afterburner on...fuel vanishing...

absolutely marvelous =)

[MyFatty69]

nice engine, its a greddy lil fker

[wispers187]

i can literally see the fuel being draind from the tank, that thing EATS the fuel

[rcfreak2493]

omg you just gave me an erection with that! thats the sickest thing ive ever seen!

[Cjudd001]

looks awesome. I hope you have some type of filter on your compressor inlet.

Compressor that close to hte ground will suffer FOD for sure.

[MrSaunter]

Hehe. Look at the fuel tank =)

[tn66367]

vtwinmesa you are an idiot.

[51235465789]

lol just watch the gas tank go down

[BucknutDolfan]

I want one! lol

[fordyrox]

that afterburner sure chews up petrol :)

[cmccarthy]

That thing is bad as hell, man.

[fran963852741]

lol look at the fuel tank :D

[vexviper]

Man that engine sucks the fuel. Awesom video!

[havaden96]

woow when the afterburner goes you can realy see the fuel dissapear in the tank!!

[isctony]

wow that thing drinks some fuel!!

[rb26capri]

GUZZLER

[RobscoRC]

wow, you can see the fuel going down :P

[fernando13e]

and how much did it cost?

[dobsonator]

omg that thing sucks the fuel up.

[vtwinmesa]

a thing about afterburners few realize is that in a turbo fan engine there is a flow of fresh air supplied to the afterburner stage, but in a jet engine that is not possible. I spend a lot of time thinking about this and the only option I see is to build a ram air cone around the engine that would do the trick but only from a certain speed upwards , at zero speed not applicable

[knobby4]

@vtwinmesa

Not entirely true, about 60% or the air going through a true turbo-jet is used for cooling, the rest is used for thrust....hence the cooling air still has a nice amount of unburnt oxygen, this we can ignite with the use of the afterburner. If all the oxygen we already burnt in the engine, the A/B would not ignite at all.

Cheers,

Smithy.

[vtwinmesa]

@knobby4 hmmm yes, heard that before, but air at that temperture has very few oxygen, but certainly some left. when the a/b is on does it burn inside the a/b chamber too or just outside as seen in this video?

[kinsley2108]

@knobby4 true, turbojets don't bypass air around the core, but they do direct some air further into the combustion can(s) to shape the flame. This is called primary, secondary and tertiary airflow, only the primary gets burn't which is about 60% if I remember correctly. Secondary and tertiary air doesn't get burn't, therefore it's oxygen rich, making afterburners possible in turbojets.

[Inklebonker1]

@knobby4 how does an afterburner work anyway?

[XxCODxXd3ath]

@knobby4 Ok a jet engine is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. the engine burns fuel with air from the atmosphere. The burning fuel heats and expands the air, and this hot air shoots out of the exhaust-end of the engine to create thrust. Most newer jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds.

[XxCODxXd3ath]

@knobby4 One part of the turbine sucks in air and compresses it before the fuel is injected. The back portion of the turbine acts like a windmill, extracting energy from the exhaust gases and using the energy to spin the compressor portion. Newer turbine engines are extremely efficient, and there is still a lot of oxygen available in the exhaust stream.

[XxCODxXd3ath]

@knobby4 The idea behind an afterburner is to inject fuel directly into the exhaust stream and burn it using this remaining oxygen. This heats and expands the exhaust gases further, and can increase the thrust of a jet engine by 50% or more.

[knobby4]

@XxCODxXd3ath

Can I ask why you're telling me all this, I already know how they work.

[kinsley2108]

@vtwinmesa true, there are differences between turbofan, tubojet, turboshaft and turboprop engines. Turbofan does bypass most of its air around the core, whereas turbojets takes the whole mass airflow through the core as there is no bypass, however, some air in all engines doesn't mix with the fuel, it is directed further back in the can to shape the flame into what is known as a toroidal vortex. this air is called primary, secondary and tertiary airflow. Only the primary air is burnt, secondary

[ceessaay]

good job !

[bigdnelyria]

Defantly a fuel hog. You can see the fuel drop when the after burnner kicks in.

[STtheboy]

wow nice craftsmanship

[dv8munky]

dude, would love to see it go down the track!. watching how fast the fuel went with that thing only running intermittently, you know its gotta drink it running down the track.

[ck23a]

Sweet! Look watch the fuel consumption!

[kurtzy04]

Thats a bloody good job you done on this mate, 100/100!!!!

[punisher01737050445]

die zieht aber denn sprit aus dem kanister mann o mann

[ozbloke74]

thats supa kool, hope it runs hard when ya get it on the strip. Why did u place a chock behind wheel out of curiosity?

[knobby4]

My carport/garage floor has a bit of a slope to it and I didn't want the car rolling backwards.

Cheers,

Smithy.

[diti230]

look the benzine( or what ever it is) how fast its burning

[TamiyaTerraOne]

All show....No go??

[knobby4]

You're quite right, it is fairly slow off the mark, but has plenty of top end speed, 183.56kmh so far, recorded at WSID drag strip just over a week ago.

Cheers,

Smithy.

[sstroh08]

@knobby4 the full size jet machines are the same way off the line they are slow but just look at the other end of the track, i figure this is because they are driven by thrust instead of mechanical power, btw that rig you built is awesome! i had never heard of such a thing until now

[addictedtopepsi]

0_o are u running kerosene

[knobby4]

Yes, it's Jet-A1 fuel.

Cheers,

Smithy.

[krugtech]

Have you had it up to 100%?
