Wingtip vorticies: Their benefits?

[Tonala2k]

I don't like A Squared. sounds like this FastestPA something or another user on here. I got your back Rush. You messed up and said so. I can't count how many times I've told a student to pull back on the rudder. :O

induced drag is related to AOA, not really speed.

Right, you "misunderstood" You thought the question asked about winglets


Sure, that's why you wrote

"Wingtip vorticies help to reduce induced drag by increasing the lateral flow of air over the wing."

Uh-huh, you wrote "wingtip vortices" because you really meant winglets.

Look, it's very clear what you meant, and you clarified exactly what you meant in your second post. Now you are trying to claim you didn't really say that and it's all a big misunderstanding.

Or......you could talk about what we are talking about. Look man. You got some kind of problem with me or something? Did accidently poop in your cereal or have sex with your daughter? Get a life man. I messed up and said so. I have never seen you conceed to messing up. According to yourself you "know everything". I typed one thing while I was thinking another. And please, don't give me that crap about "Russian doesn't know what Russian's talking about". I did extensive research on winglets and wingtip vortices at my University. And, it was all done in a sub-sonic wind tunnel. Take that back to basic aerodynamics school.

I don't either. A Squared brings down the quality of the board. A Squared does not post in a positive manner. A Squared also does not post correct information and claims that it is, on a regular basis. After posting, A Squared will make derogitory remarks to others to try and make himself sound correct.

Good luck A Squared. I hope you find happiness somewhere.

You guys take this trivia pretty serious.

Remember that in flying it is not WHAT you know but WHO you know that really matters.

And AOA isn't related to airspeed?

How pathetically juvinile can some of you get? Whatever depth you intend to sink, you're doing well.

A Squared has been posting here for a long time now, before this board was in it's current generation, and the one before that. I don't believe I've ever seen him post frivolously. I also keenly admire his tenacity in driving home a point. His are routinely among the most accurate, germain, and well written posts on the board, and long have been. If you don't like it, perhaps you ought to do a little more research before you open your mouth. He doesn't cut you much slack, nor should he. Get over it.

And danged if you still weren't wrong. Some people's kids.

I got your back Rush.

And here we thought junior high was out for the summer. Go figure.

Not particularly surprising, now that you mention it. You probably shouldn't mention it too much, though.

I suppose that all depends on what you want to do, where you're at and which "airspeed" you're talking about.

Looking back at your previous posts on this topic, I hope you didn't actually graduate from your "University."

You had "extensive research" in a sub-sonic wind tunnel?? Did they actually turn the blower on?

O.K. smart guys - here is another question.

As an airplane slows and maintains straight and level flight, will induced drag increase or decrease?

induced drag increase,
parasite drag decrease
Are you really asking this private pilot level question? Or do you have some wierd twist on this?
By the way, the induced drag is also attributed to the rearward horizontal component of lift at a high angle of attack.

I just like seeing heavies come out of the clouds on a humid day, beauty eh?
