Need BIG help with Gripen airfoil !!!

[#Leo#]

The data would be just for some work on college, for my collegium "Mechanics Of Flight"

Leo if you need a 3D of the Saab JAS-39 Gripen I would be glad to hook you up with over 5 3D models. You would need DNM Viewer to view them though...

Cobra2 --> please send them to me ..... if you can send them to lstipisic@gmail.com (first letter is small L) . thanx

[Cobra2]

They are NOT my models though, other people created them.

I bet Leo, you want to create a flight model and check your predictions with actual data.

What kind of airfoil Grippen uses is most unlikely to find. Even if you knew that it was a 64A series, it surely would be a modification to better suit Grippen's needs.

But u can easily find the aspect ratio (=span^2/wing area), taper ratio (chord at tip/ chord at root) fuel fraction (weight of fuel /total weight), u can have an accurate idea of T/W ratio and then "play" with the specific excess power equations, to predict (at a reasonable degree) the performance.

valk-What happens if he doesn't have some of these figures?

[valkyrian]

Raptor my friend, these data can be found all over the internet.....

Agreed. Leo, why don't you do an F-15 or something...?
