View Full Version : Isn't lift part of drag?

Fortune magazine online has a photo essay about their new 787. On one
page, http://money.cnn.com/galleries/2008/fortune/0804/gallery.boeing_dreamliner.fortune/16.html,
they make this statement:
The Dreamliner's wingspan is 197 feet, or about 25% longer than a
similar-sized plane, which increases lift and reduces drag.
I thought that lift, in addition to causing a net upward force on the
wing, also contributes to the drag force on the wing as well. If this
is the case then increasing lift should also increase drag. Did I
misunderstand?

For any fixed wing geometry, increasing lift increases drag as you
say. In this case they change geometry and get more lift with less
drag. OK?

Higher aspect ratio wings produce less induced drag; think sailplane.

So their information is correct but incomplete. I expected that was
the case but I wanted to make sure my base understand was correct
first.

Well, it's a trade off. it's possible to do both by various means.
arifoil selection, planform and so forth. It'd be more correct to say
that they're eliminating unneccesary drag.

The lift and drag curves for any given wing are a function of wing
design. Although induced drag is a product of lift creation, the design
of the wing could easily change the lift and drag coefficients and make
the wing more efficient.
These are complicated inter-relationships, and sometimes, when doing an
article in a non technical venue, a writer will simply present the tip
of the iceberg.
This isn't necessarily wrong but you will probably notice a distinct
difference between an article on wing design written for Fortune as
opposed to one written for Aviation Weekly :-)

It could be more efficient. The Mooney wing produces more lift for the
amount of drag than a Cessna wing.

From the original statement, it seems clear that they're
referring to the increase in efficiency that come from aspect ratio. I
wonder, now, if that increased span was made possible with the use of
composites instead of aluminum? Longer wings flex more, and aluminum
fatigues faster, I think, than composite construction. And carbon or
aramid fibers are stronger per unit weight than aluminum.

There are a lot of trade offs, and the gate spacing might also be larger at
the airports that the Dreamliner is expected to serve. Also, IIRC, a few
years ago, Boeing talking about future aircraft with folding wing tips to
overcome some of the spacing problems at the gates. I also agree with you,
that advances in materials also play a major role.

I think you can say more and explain less than anyone I have ever heard.
Do you think the value of any writing can be most accurately expressed by
it's printed weight in pounds?

Not always. There is no trade off between a model-T and a modern car.
Technology innovation allows for increased efficiency that does not
necessarily require any trade-off other than the RND time required to
develop.

It's not going to be that big. The widebody Busses ( A 330 and 340) are
already massive with a much larger span than the 747 so it shouldn't be
an issue.

There is, actually. You can drive a Model T across a field that even a jeep
would get bogged down in.
Also Ts are much more fun to drive.

no.
it would be valid to say that they were using a geometry with less
induced drag. drag isnt necessary or unnecessary it is drag.
you cant eliminate it, all you can do is try hard to find the design
shape that has the least of it.

Well, by unneccesary drag I mean stuff that is not as a result of
creating lift. Improved fillets and seals, for instance. I agree, the
planform and airfoil sections are designed to do what they do and
collect drag as they do

Yeah, you did. i didn't mean for the one thought to relate to the other.
Having said that, airliner wings are really complicated. Boeing wings
are a marvel to look at. The 757 wing is simply mindboggling. The center
section has a supercritical section in order to ammelorate drag induced
by the shick wave at high mach numbers. I'd say the 787 is going to
carry on that tradition with further refinements in that direction.

No, I only give a hard time to cretins!
