What is the cross section of Su -27 wing?

The aircraft adopts wing-body fusion technology, with a single wing hanging on the wall, a smooth and curved wing extending forward from the wing root, and a normal layout with double vertical tails. The wedge-shaped inlet is located in the front and lower part of the wing-body fusion body, which has good aerodynamic performance. There are grid-shaped auxiliary doors at the bottom and side wall of the inlet to prevent foreign objects from being inhaled when landing. All-metal semi-monocoque fuselage, slightly drooping nose, a lot of aluminum alloy and titanium alloy, traditional three-beam wing.
