How are foam cores shaped for tapered and swept back wings?
I understand that many constant chord, constant thickness rectangular wings use the same sized airfoil shape from root to tip. Let's assume the wing uses a classic NACA airfoil shape such as 650-18.
How would a foam core wing with a classic NACA airfoil shape, swept back 10 degrees be shaped? Is the wing, using the same airfoil shape, NACA650-18 just rotated back 10 degrees from the root? In this case, in cross section longitudinally (along the plane's y axis, in the direction of airflow), the actual airfoil shape would no longer be the same shape as the rectangular non swept wing, even though the geometric perpendicular cross section of both wings is exactly the same. Is this correct thinking?
