Turbine car update

[EddieWeeks]

I have been cutting and welding stainless steel for a few hours..

New pics here.

damn, where did you get your body?

[Toyotatogo]

Now I understand how this car will work .... the hot air from the turbine will blow the fan thus turning the wheels correct.

[Hz-R]

I think this concept is way cool!
But why don't you just use the housing of the turbo where you got the turbine from? Was kind of expecting to see that in these new pics.. Wouldn't that be easier and probably more effecient?
Should be easy enough to connect the jet engine to the intake, and the exhaust would come out in the direction of the axl. Connect a bent pipe upwards and you're done!
Just a thought...
Good luck building!

Toyotatogo... you got it..

Hz-R: The housing of a turbo weighs about 10 lbs and does not
have enough room inside of it for the amount of air comming
out of that turbine.. basicly its to heavy and too small..

Bellsouth just started this bandwith limit junk..

The turbos on normal car engines aren't that big, and I guess a normal car engine propably puts out quite a big amount of hot gasses at full throttle. That's why I thought that would be the way you're going.
Then again, I don't have any experience with jet engines, they probably are very powerful and the added weight sure is a factor!
Can't wait for the first 'test report'
Happy weldin'!

Another problem is I want to be able to have the car sitting there with
the turbine running at idle. Even at idle it still turns 35,000 rpms and
moves a lot of air... With my hosed up design that air will just go around
the turbo, but if I forced all that air into a turbo with a housing it will
most likely back pressure the turbine and overheat it..

My plan is to run it like this... cool and safe... then install a adjustable
plate just behind the turbine to deflect the hot air down..
This will force more of it to the bottom half of the turbo... if I force to much
it may run hot... The key is to make it adjustable..

Ah, didn't think of that, you've obviously thought this out more then I have! ;-)
With a turbo housing you would then some sort of valve as well, which would add even more weight..
It's pretty much all pioneering work you're doing there anyways, trial and error.. If you get it to work, this thing will surely scream!

Good luck!

Eddie-

I dont have a total understanding of how it will work but basically the exhaust from the turbine with spin that paddle type gear correct?

Wouldnt there be a potential danger in melting the body or any other plastic parts on the car? I believe those exhaust gasses will be above 500* C?

What about intake? Wouldnt the turbine need to be directly exposed to the air, not just sucking it out from inside the body?

Or is that where this turbo you keep talking about comes in to play?

Looks awesome!

[EddieWeeks]

Every thing that goes in the car is in the pics.. It runs more like 600 C,
that is why the box houseing is all Stainless steel. I am just going to cut
a large hole in the back of the car body to let the exhaust out and a few
smaller ones for the intakes...

If it the box housing heats up the car too much. I will install some Stainless Steel
foil around that housing. I may even attach a small fan to one the drive shafts
to make it self cooling...

I think it will be fine... I have installed turbines in all foam airplanes before.. no problem

Eddie, I know you iz lookin' forward to finishin' up and turnin' dat sumbeach loose.

[Piggy89373]

I bet that thing is going sound awesome...just the freakish high speed whine of the turbine. Man, when you get it finished and do a test run on video, don't add any music to the video.

[EddieWeeks]

I have been doing some checking and only with minor assumptions
I calculated the power to the wheels to be around 8,000 watts..

An electric car would have to draw 330 amps with
20 cells to get this kind of power.

But then again, you never know whats going to happen... It
may just burst into flames... hahah

Eddie

[NotWalkinBlind]

If it does, we wanna see that, too.

But have two versions of it... one with just the sound and one with music.

Now we need suggestions on the music... my first impression of something suitable would be... uh... "Whole Lotta Love"?

[Piggy89373]

Guess that's better than "I don't want her, you can have her, she's too fat for me".

Actually, I was thinking more along the lines of Disturbed, "Sickness"

[NotWalkinBlind]

Yeah... cool with that... or any other band that Zep paved the way for.

More suggestions, peeps... let your imagination run wild on a Friday.

[nitrosportrules]

go with drowning pool, bodies and time it so when you hit the gas the song gets good(if you know what i mean, and if you listen to the song you will)

[CENthasizer]

when do you think you will have a vid of your test run up eddie?

Yo eddy I aint been around much lately buis keepin me away..but man you got a sweet idea on hand...Im thinkin...wastegate...have the turbine and a titanium tube with a servo that will work sorta like a nitro carb...let just enough air through but not enough for it to move...hit the throttle and open the gate and boom all the air from the turbine rushes through sendin that sucker 175 mph...LOL...Im gonna draw up what im talkin about tomorrow mornin and let you see what im really talkin about...i love the idea and the skills you are showin...thats awsome!

[mtrsprt]

Eddie, just some constructive criticizm.

The design of air thrust to mechaincal energy, is going to lose about 70% of the efficiency of energy during the transfer. Im sure, you know this.

Isn't this type of design also going to need hundreds and hundreds of feet, to accelerate?????

Cory

[EddieWeeks]

I don't disagree that it may be 30% efficient, but I was wonder
how you came up with that number..

Eddie

[mtrsprt]

It was mostly an educated guess, but transfering kinetic energy to mechanical energy is a huge loss.

Anyway, I wish I had a turbine to play with!!!!!!!

Your tunnel that your thurst is going through, might want to be just barely slightly larger than your turbine gear fins, to make sure you can capture as much thrust as you can into the vanes.

[NotWalkinBlind]

Eddie, yer bein' too quiet... what's going on?

How 'bout if we all go outside tonight at 9 P.M. Eastern time, and you rev it up a coupla times so we can hear what it sounds like?

[EddieWeeks]

I'll take some new pics tonight..
