Mental Jet turbine powered tractor Great Eccleston Show 2008 pulls trailer

[richardarichter123]

wicked puller

[steelhorse1979]

what is the rear wheel speed on this 

[umdiecker]

Happy festivities, all. Can't wait 'til next year's full pulls at Great Eccleston! More videos of tractor pulling soon!

[brenthoser99]

lame ass for not letting embed. how else are peeps supposed to know on websites.

[umdiecker]

@brenthoser99 turned on now - it wasn't turned on by default for some reason. Feel free to embed!

[JGMagoo]

Basically, a blowtorch against a pinwheel...with the pinwheel geared to the rear wheels.

[ahimel]

I think as a next logical step these guys need to step it up with small scale nuclear reactors. Go big or go home.

[psychotikpaisano]

Gear driven turbine?

[kladivous]

Where does the gear reduction occur on this type of rig? I hypothesized that one could use the gearbox from a turbofan engine to achieve a correct input RPM for the rest of the transmission. Anybody have any insight?

[BR4DL3YY]

i would of thought he need more tread for more traction :S

[brillabeast]

@BR4DL3YY They cut the tires like that so they dont pile dirt infront of the sled (making it harder to pull)

[manga12]

The turbine is a jet engine, but instead of using the thrust from the pushed air, it uses the rpms of the shaft to propel things via a shaft. about the same principal.

[umdiecker]

Indeed

[manga12]

Jets also have fewer moving parts just the stuff on the shaft and the pump for the fuel the rest is propelled by the thrust pushing the compressor which turns the inlet fan to feed more air and compress it as it goes down the lenght of the engine.

[Transmash15]

No no and no... The turbines from that tractor aren´t jet engins... That´s 4 Isotov heli. turbines...

Trust me i know it.... Im a mechanic and webmaster of an Tractor Pulling Team...

Sorry my english is bad

[manga12]

dude a jet engine is a type of turbine, they are just a smaller version of a large jet engine that would use thrust, these use torque from the rapid spinning of the engines.

[Transmash15]

sorry, i thought you mean something else

[manga12]

Its ok man, they are the same type of engine only differant names, and the way its used is differant, thrust verses the rotation in the case of the helicopter and tractor.

[kladivous]

Maybe you have some insight that could answer a question for me.  I am wondering if there would be any advantage to using a large turbofan engine on a tractor. Without the fan of course. Using the same gear reduction to turn the rest of the transmission. These heli engines work well but I always think bigger. What do you think?

P.S. your English is much better than most of my fellow Americans ;)

[AgonxOC]

@manga12 No that is not correct. A turbine is part of a jet engine, but it is not a jet engine. The turbine spins a shaft connected to the compressor which compresses the air, the air then enters a diffuser, and then the combustors. As the hot air/fuel comes out expanding it moves the turbine. The turboshafts will have one or several free power turbines to move the shafts.

[manga12]

Come again, its the same principal the hot press on the venes of the shaft turning it creating the spin, with compresses the hot gas sustaining the engine, instead of using the gasses to push forward like an aircraft uses the high spin from the shaft through the gearing to convert it to torque.

[AgonxOC]

@manga12 I am not sure what you are trying to clarify here....

[manga12]

runs on the same principal you have a shaft with venes on it and uses hot gasses to spin and sustain the turbine.

flip it around a jet engion is a type of turbine.

*baby duck

[babyduckteam]

hey thats the redoutable, and no it isnt a horrible engine for tractor pulling, baby has them also, and he is european champ!!!!!xD

[11jstedm]

this is a horrible engine for tractor pulls. It's gets all of it's horsepower from rpms not tourque like a diesel

[umdiecker]

Pretty darn successful at the show though.

[pbpaulieb]

The turbine powered tractors are so good that some circuits now have different classs for them.

[11jstedm]

ur right

[BadAzzS10]

You want RPMs in tractor pulls. RPMs = wheel speed.

[beeson1981]

Don't forget that horsepower is just a measurement of the torque an engine produces multiplied by the revolutions it's doing at that time.

HP = (torque x revolutions) divided by 5252

Turbines aren't horrible engine for tractor pulling at all! Large turbines produce buckets of torque but they need to be up to speed before they do so and that's not an issue with tractor pulling as they can wind up before they start rolling.

[blazerboy2011]

im not calling you a liar beeson1981 but were did you find the HP = (torque x revolutions) divided by 5252 ive never heard of that ?

[4Q3W2E1R]

mech shop class :-P. its common knowledge amongst gearheads

[gigobait]

@11jstedm what are you talking about? Gas turbines have tons of torque. 

[AgonxOC]

@gigobait Yes, when they go through a reduction gearbox. 

[AgonxOC]

@11jstedm Actually once put through a reduction gearbox they make great torque. A small turbo-shaft can make upwards of 2000 FT-LBS at about 2200 RPM. The one I fly makes about 1315 FT-LBS at about 2200 RPMs on the reduction gearbox, granted it is spinning at 37,000 at the free power turbine. Those look like Medium sized, so they could be making 2000FT-LBS easily and with four attached that is about 7000FT-LBS give or take with loses.

[JGMagoo]

@11jstedm Torque can be multiplied by gearing. Horsepower cannot be multiplied.

[jucagave]

gas guzzlers put it to use..........

[Kate800]

Oh sorry my bad, never write on youtube when your drunk

[Kate800]

A jet is the sort u find in rockets. :( this is a dumb dull turbine,

[umdiecker]

This is a JET TURBINE engine. It generates rotation through combustion of fuel and compression of air from the turbine fins. The driveshaft attaches to the rear wheels by means of a gearbox/clutch.

[thegerbil123]

Surely a rocket has Rocket motors, its in the name...

[umdiecker]

Rockets are just burning fuel firing out through a venturi, channeling thrust and pushing the vehicle through high-speed gases. Jets usually use a turbine to compress air into the combustion chamber, burn & expand the air/fuel and consequently turn the internal turbine blades to drive the central shaft faster.

[AgonxOC]

@umdiecker It is not a venturi, it is a convergent-divergent nozzle. And a jet engine (Turbofan, turboshaft, turboprop) uses a compressor to compress the air. Turboshaft and turboprops typically have a free power turbibe, meaning not attached to the atcual engine and sometimes it even spins in opposite directions.

[Wallawapa]

Thats Definately a Turbine! :{

[Kate800]

Thats a Turbine, not a jet

[justsir1999]

Tractor pulls?? i just thought that this was a red neck urban myth.....Man i got to get to one
