The grille is comprised of five ( 5 ) horizontal airfoil sections,layed back at a 21-degree angle,and each airfoil element is configured "nose-down",with the cord line of the highly cambered foils angled,tail-up,at 30-degrees

based on this description i made the following sketch... i hope i interpreted things right here
is this somewhat what it should look like?
what's missing from the description is the relation of the length and the spacing of the foils.
than again, the angles give enough indication to try and build some sort of prototype
