Airbus' wings
 

Do the A318 to A340 wings have a NACA code? Are the wings supercritical? Does anyone have info on the design, such as L/D ratio, CP location / movement, critical AoA etc...

And what about Boeing wing design?

Would like to compare these and use them as real-life examples in ATPL ground school...

Thanks.

Uptrim Disable,

Not aware of any specific published section used on airbus aircraft.

Are the wings supercritical? Yes

Does anyone have info on the design, such as L/D ratio, CP location / movement, critical AoA etc...

Yes Airbus does, the data is worth millions.

Airbus does all this initial design on a computer used computational fluid dynamics, then wind tunnel tests the computer model. On the A340 it cost over 600 million to do this.

A lot of the Boeing stuff is available, if you have a look at The Incomplete Guide to Airfoil Usage it lists the sections for some Boeing models.

The Boeing airfoil coordinates are available at UIUC Airfoil Coordinates Database

A number of programs and links to other sites that can plot and predict airfoil performance can be found at UIUC Airfoil Data Site
