Delta Wing at Le Mans?

The Budweiser-Spaghetti one is precisely what I had in mind!

Tried to find more on cars, but the spaghetti one really stood out!

When it comes to cars, though, Mott was the best by far.

Wish I had that sort of drawing talent!

Wasn't sure if anyone was reading my fine print; yes, 'twas so fine

More DeltaWing Bab-bling:

I just tripped over this 2012 Le Mans Special Edition freebie from Racecar Engineering; 86pgs of reprints, mostly; fresh adverts a course...

Nice, if you've missed a few issues over the last few years, or missed years over a few issues (me)

From the above link:

"Having seen the car in action, we can confirm that the unconventional machine works very well, especially through corners. Running in an experimental class, the DeltaWing will not be classified and the ACO have asked the team to run a lap-time of around 3:45, so as not to upset the top runners."

Hmm.. Seems disappointing that they'd give it a target lap time like that, but then again there isn't really a rule set they're restricted to. So it might not tell us much about the car's potential after all..

It's 20 seconds off the pace, how good can it be in the corners. And it can't be lack of hp because we were told it only needs 300 hp because it's so efficient.

Yea - it did take a bit of squinting to read the caption without my glasses!

The instant I saw the pic I thought of Mott - some really wacky but brilliant stuff came off of his sketch pad!

Actually, my memory was wrong as well - I actually was envisioning 'Big Daddy" Ed Roths work, but only Motts name came to mind!

if they won't let it run a competitive lap, then they should take it off the track. If it can't do a competititve lap, they should say so. The whole thing is about seeing what this radical new concept can do. Speed restricting it negates the whole process. That is sad, considering the work put in and the interest generated.

[a. pettipas]

So, how do we know DW's 1.6L turbo engine puts out ~300hp?...while it is evidently not a 1000+hp fire-breather, if this project is not bound by the ACO P2 class rulebook then who's to say it isn't dialed up to something (probably) easily attainable like 500-600?...I suppose a relative comparison of trap speeds and/or sector times would go some ways towards supporting or disproving this notion...I'm sure that information is out there somewhere to be found but I don't care that much to look for it

Hmmmm..... I have a hard time believing that there wouldn't be at least one of the drivers who would eventually "forget" about an artificial lap time limitation and lay down a flyer...I know I would.

[swiftdrivr]

I agree that a thousand horsepower dog can look pretty good against a great car with half the horses. So restrict the horsepower, and post it so we can see if the thing works or not. Restricting lap times tells us nothing at all.

from the deltawing site.

ENGINE
Type: 4 cylinder 1.6-litre Nissan DIG-T (Direct Injection Gasoline-Turbo)
Maximum Power Output: 300bhp at 7400 rpm

I'm missing something, where is the perception coming from that they are limited on lap times they can turn?

[swiftdrivr]

Post 166 above.

[EACIII]

I would think you could get a little more then 300 bhp out of a 1.6 liter direct inject turbo motor if you wanted to. Its a recycled race motor from something else they stuck a Nisson badge on, I just forgot what.

IIRC, Ray Mallock Ltd. developed this engine for their Chevrolet Cruze WTCC program

Wow. The hatred in this thread makes me feel even younger!

Maybe we should combine this with the "let's hate on the new Indycar cause it doesn't look enough like the 70's!" thread..

Why do you have to bring this kind of stuff into an otherwise fairly interesting discussion?...love or hate DW, who really cares?...such a radical deviation from race car design precepts is never going to be swallowed en mass and that's OK, isn't it?...there is nothing wrong with exercising critical thought when debating the merits and deficiencies of this project

Read that they are NOT using the active diff in the car? Anyone hear anything about that?

[R. Pare]

Don't know how they could possibly get around a corner without it.

[Northwind]

I found a picture of the Delta Wing with the bodywork off!

[swiftdrivr]

Usually its the left that labels anyone who doesn't think just like them as "haters". Sad to see people using that kind of technique here.

[starkejt]

The Delta Wing sucks. Everyone who likes it sucks. Everyone who disagrees with me sucks. Everyone who is reading this sucks. That tricycle is sweet, though.

Your hammer is not big enough. You are way too gentlemanly.

Thanks .... Jay

YOU suck.

[starkejt]

I'm sorry for lashing out. I'm just so jealous of Dan's tricycle. I didn't mean to take it out on you.

[Purple Frog]

The Delta wing with active diff installed, sans bodywork...
FWD model was thrown out, too much wheel spin on steep uphill starts.

[starkejt]

That does not look like the one I always asked Santa for as a little boy, only to receive a beating each Christmas morning instead.

[Purple Frog]

That explains your previous "sucky" perspective on the world.

does this vehicle represent progressive thinking or anarchy?

i was against it before i was for it (or something to that effect)

interestingly it is the leftist progressive socialist French who are allowing this American Dream Machine to run free LOL

[Dennis Valet]

Don't know how they could possibly get around a corner without it.

lay a sledgehammer on the ground, push on the end of the handle, see how little force it takes to rotate the hammer. Same concept, the front wheels need to exert very little force to rotate the car.

[Peter Olivola]

Now, try the same thing with the sledgehammer traveling at 200MPH.

Have you noticed the LeMans racing version is much shorter than the show prototype? I read they had to remove 3' (!) to fit into the pit box and meet the rules. Honest.

Just a minor oversite.

Oh man, the TopGear commissioned DeltaWing replica (Westfield sports car running gear) which will be cruising this year's LeMans paddock...

The home made DeltaWing is finished!

[EACIII]

Notice when you rotate the handle the head stays in the same spot. So basically you would point the nose of the Delta thing into a corner and the heavy (head end) would go straight off the track. But with the front pointing to the corner.

according to http://www.deltawingracing.com/the-car/ Page on June 8, 2012, their active diff won't be used.

"Crown wheel and pinion: Planetary final drive potentially featuring efficient torque vectoring differential technology"
-Steering:
"Bevel quadrant steering box without power assist. Rear axle torque vectoring functionality will not be used in race mode"
-Features:
"The differential features an efficient variable torque steer/differential speed-controlled planetary final drive reduction layout"

I designed that diff for BAR in 2000, really cool piece, we had to operate it mechanically though to get around the rules, and it was subsequently banned the day we were assembling the gearbox for testing as A.N.Other team didnt have one. An electronic version would be sweet!!

Anyway, it was made by XTrac, they built 3 of them and the Honda guys all sent the info back to Japan and I think a version of it is used in some of their road cars.

I'm pretty sure it would be a similar design, if anyone wants to know more about it let me know, I have all the drawings somewhere.

[starkejt]

I will speak for everyone. We want to know more.
