Just wanted to let you guys know that there are real F1 aerodynamicists lurking around the forum and reading your posts - cheers for providing some quality lunch-time entertainment The underbody/diffuser thread had many of us chuckling

I would just like to say it's a pleasure belonging to the F1technical Forum Community. Thank You Tomba, Principessa -- and of course -- Manchild for all the avatars.

It's my good fortune-- to stand among the Forum's Membership.

Welcome to the forum SLC. I'm quite sure many posts have missed the mark, because many of us are in here searching for answers and enlightenment. But this is a forum, and that's what it's all about, the exchange of information and answers to questions.
I'm an electrician and just for fun one day, I convinced a person that if you reverse the plug on a refrigerator, it would heat the interior. Amazing the misconceptions we carry around. I still wonder if he sold his stove for a freezer......

Every sport has a core group of enthusiasts and this forum is it. This is what F1 is all about. The technical aspect, the personalities, the craft and of course, the shaved.
I think as long as the FIA stays true to these principals, F1 should do well in the future.
Do you think that anyone from the FIA read forums such as this one for direction? I think they would be well advised if they did.

Which team are you from?

Better yet, can you hook any of us up? With jobs or spares?

I can't say which team I work for.

And no, unfortunately not

Well, thanks for dropping by...

In your spare time (dunno how much u have) you can probably inform us about theory vs. actual practice in an F1 team.

It was smart of me not post in that thread at all

BTW, you don't need to tell us which team you're working for just name of the title sponsor or one of the drivers in 2006

Yes, the diffuser thread is an interesting one. Before you laugh though, consider that many people on here aren't F1 aerodynamicists, nor do they have any engineering background whatsoever. There are a lot of people here who are merely trying to understand what's going on without knowing how CFD works or what potential flow theory or the governing eqn's are, etc. In that sense, I don't think it's "funny" that they are trying to learn more than the average person. My only issue is when they pass off information with certainty when they have no background or experience proving it as such.

I know you can't disclose what team you work with, but what do you do? Track setup? Experimental? CFD? How reliant is your team on CFD? What, if any, types of flow viz do you guys employ in your experimental facilities? Schlerin's, shadowgraphs, PIV's, etc.?

Yarn tufts? Haha

How are you guys coping with the '08 regulations. How do you feel about the "CDG" - I'd love to hear your opinion as my thesis is a wake survey (among other things) of a CDG wing using Fluent.

Bad day at the office? What's with the sarcasm? How about some constructive criticism instead?

Glad, I guess, that we could provide some much needed entertainment in such a stressful field as you're in. Maybe you could throw out a bean or two to really indicate that you are truly an aerodynamicist. Can you give us a single paragraph take on that thread?

After every flight, pilots fill out a form called a gripe sheet, which
conveys to the mechanics problems encountered with the aircraft during
the flight that need repair or correction. The mechanics read and correct
the problem, and then respond in writing on the lower half of the form
what remedial action was taken, and the pilot reviews the gripe sheets
before the next flight.
Never let it be said that ground crews and engineers lack a sense of
humor!
Here are some actual logged maintenance complaints and problems as
submitted by Qantas pilots and the solution recorded by maintenance
engineers.
(P = the problem logged by the pilot.)
(S = the solution and action taken by the engineers.)

P: Left inside main tire almost needs replacement.
S: Almost replaced left inside main tire.

P: Test flight OK, except auto-land very rough.
S: Auto-land not installed on this aircraft.

P: Something loose in cockpit.
S: Something tightened in cockpit.

P: Dead bugs on windshield.
S: Live bugs on back-order.

P: Autopilot in altitude-hold mode produces a 200 feet per minute descent.
S: Cannot reproduce problem on ground.

P: Evidence of leak on right main landing gear.
S: Evidence removed.

P: DME volume unbelievably loud.
S: DME volume set to more believable level.

P: Friction locks cause throttle levers to stick.
S: That's what they're there for.

P: IFF inoperative.
S: IFF always inoperative in OFF mode.

P: Suspected crack in windshield.
S: Suspect you're right.

P: Number 3 engine missing.
S: Engine found on right wing after brief search.

P: Aircraft handles funny.
S: Aircraft warned to straighten up, fly right, and be serious.

P: Target radar hums.
S: Reprogrammed target radar with lyrics.

P: Mouse in cockpit.
S: Cat installed.

P: Noise coming from under instrument panel. Sounds like a midget pounding
on something with a hammer.
S: Took hammer away from midget.

I've seen this before and was going to post it before I was assured that it's been arround for ages and everyone's already seen it.

Classic all the same.

Most definitely, but it almost makes me pee my pants from laughter, and illustrates some of the fun aspects of high tech and engineering.

I fail to see the sarcasm (and I love it!). C'mon f1.redbaron, I don't think SLC is complaining about the quality, he is saying thanks. After all, Reca was so kind as to spend some of his time on us and we all know the caliber of his posts (I have no idea of CFD, but I know a couple of things about roads).

Anyway, it's hard to know if you understand anything until you try to explain it. When you heard questions and explanations from newbies on your field of expertise you realize how hard is sometimes to understand everything in "one big gulp" and you find it amusing. It is different to chuckle with one post from chuckling about the poster.

May I say (with my heart in my hand, no bad intentions at all): don't be impatient, breezyracer? You'll see, I'm thoroughly trained to dismiss acreditations. I couldn't care less if SLC is Adrian Newey: I only count good explanations and good writings as proof of a good mind, specially in an anonymous forum (well, you can see I don't care about anonymity, but I have my own reasons). You could have slept through your entire master (in the current university system). If SLC has something to say, he will.

So, welcome SLC.

And of course, welcome breezyracer. I hadn't time to say it before: your posts are straight to the point. It seems to me you are a valuable new member of this forum and the thread on diffusers you participated on has bring new people that has illuminated us a lot. Keep up the posts and, (if you allow me to say it, again, with the best of intentions) be mellow to newbies!
