Wingletted 767...

Hopefully over rolling and striking a wing tip onto the surface on a crosswind landing would not be problem in that one!
 
Control surfaces are. . .?

Aircraft flight control surfaces allow a pilot to adjust and control the aircraft's flight attitude.
Development of an effective set of flight controls was a critical advance in the development of the aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, but once aloft, the aircraft proved uncontrollable, often with disastrous results. The development of effective flight controls is what allowed stable flight.
This article describes controls used on a fixed wing aircraft of conventional design. Other fixed wing aircraft configurations may use different control surfaces but the basic principles remain. The controls for rotary wing aircraft accomplish the same motions about the 3 axes of rotation, but manipulate the rotating flight controls (main rotor disk and tail rotor disk) in a completely different manner.

Trust me. It ain't to make it look pretty. If they could save a few bucks by installing bright yellow wheel-pants on all of the mains they would.

You might do a bit of research, Max. True, some devices are 'pretendlets' there mostly for looks but Aviation Partners has developed specific winglets for a number of aircraft and fuel savings are, according to different sources, above 7%.

FWIW, the concept of winglets came before the Wright brothers flew. It was just that the application and technology of the time caused more drag and carried more weight than savings provided. Not so anymore.

First app was in the 60-70s when the USAF bailed a KC-135 to NASA and found considerable savings. But it was engines or winglets and the USAF went with winglets. NASA also bailed a Continental DC-10 and produced similar findings but the airplane would have to go through recert. Not worth it.

FWIW, the same guy who came up with area ruling was pondering one day. Whitcomb set aside time every day to just THINK. He hit upon the idea and went back and found early research and built on it.

First winglets showed up on the Longhorns, the Lear 28 and 29 and that was 30 years ago.

So, not the latest hottie by any measure, Max. And certainly not lipstick on a pig when you save 7%.

I'm aware of the benefits of winglets. My comment was more about why are they all the rage now..?

For example the 777 didn't come from the factory with winglets, but I hear AVPartners will be making a winglet mod for that aircraft.

If winglets are such a benefit why isn't Boeing making planes with winglets out of the factory (save for the 747-400).

I guess what i'm saying is geez, it's over kill already!

Because gas was super cheap when most of those planes were designed.

Why spend a bunch of money on the development, STC, etc, when you'd spend less over the depreciated life of the airplane on the gas?

I'll put that on my beer owed tab for NJC. ;)

Because one company decided to take a long hard look at how to improve the wing. Talk to any company and you will find many consider THEIR wing about the best that can be designed. And so you have some turf to protect. Happens.

Wrong. The 777 was originally offered with a folding winglet and no one wanted it. So Boeing then developed the raked wingtip. Not as good as a true winglet but it works.

Max, you're playing with us, right? Most 737NGs from Boeing are winglet equipped. Boeing and AvPartners are working together.

Right.. please send me 7% of whatever you earn as such amounts seem meaningless to you. :rolleyes:

Footnote in history for sailboat racing buffs. IIRC, Boeing actually somehow got involved in the America's Cup defenses in 1983 and 1987. They loaned their supercomputers to Dennis Conner's team to do research on winged keels. It worked, Conners returned the trophy to America in '87.
 
Pan sear it, a little au jus with a smidgen of orange marmalade. Serve it up on a bed of Israeli couscous with chopped dates...

Man, I've got to get me a hunting rifle and head up north!

We could have a jetcareers meet and greet duck hunt. Just leave your Dick Cheney shooting skills behind. :D :laff:
 
Lan is rolling with winglets now too.

I think alot of planes look nice with the winglets.. the 767 is gonna have to grow on me.


<----- that's a 757 with the winglets right there. I think that is one sexy machine with them on there.

Agreed. I think 737 winglets looks like a tutu on a pig.

The 75? Beeeeeaaauuuutiful! :)
 
Speaking of all this...

I saw on a website once -- It was probably a java or flash thing (I know nothing about computers) that was a demonstration of an airfoil/air stream. You could move the angle of attack and see where the flow of air gets turbulent and detaches, etc.

If I sound like I don't know what I'm talking about, it's 'cause I kind of don't. I'm not a pilot, I'm a controller trying to learn more. :::ducks::::rolleyes:

Does anyone know what I'm talking about or where I could find that link??? I've been searching Google but can't seem to find what I'm looking for.
