Hello,

Just wondering if the NACA classifications are still used in airfoil design for modern airliners or are new airfoils designed uniquely and entirely from scratch?

If the NACA classification is used... what NACA classification does the 747-400 use?

Dont think you will fond they are NACA ones at all, they are Boeing propriety ones. I think they have about half dozen, called the BAC463, BAC464, BAC465, BAC466, BAC467 and BAC468.

Some data exists for them about the place as the 747 has been as a research model for some time.

A good site to work out sections is http://www.ae.uiuc.edu/m-selig/ads/aircraft.html

Modern swept wing commercial aircraft do not have the same section across the span. And no, they're not NACA sections.

The likelihood of finding any section data on the more recent aircraft is quite remote because the wing is the "top secret" bit of any aircraft. It's where lift is made and drag is, hopefully, lost and you're not going to tell the enemy how you did it.

Short answer is that it doesn't.

Most airlines in that catagory will use custom designed airfoil and often times a continuosly changing one.

That way the manufacturer will be able to "tune" the airfoil for the aircraft they are developing.
