Aircraft Having A Ring-Shaped Wing Structure
First Claim
1. An aircraft comprising:
- a boomerang-shaped front wing curving gibbously to a front of the aircraft, which has a leading edge, a trailing edge and a first and second airfoil tips;
a boomerang-shaped rear wing curving gibbously to a back of the aircraft, which has a leading edge, a trailing edge and a third and forth airfoil tips;
a first wing box connecting the first airfoil tip of the front wing and the third airfoil tip of the rear wing; and
a second wing box connecting the second airfoil tip of the front wing and the fourth airfoil tip of the rear wing, wherein the trailing edge of the front wing, the leading edge of the rear wing, an internal surface of the first wing box and an internal surface of the second wing box form a center opening.

Abstract
The aircraft includes a boomerang-shaped front wing (4), curving gibbously to the front, having a leading edge (4F), a trailing edge (4B) and the first and second airfoil tips (4E1, 4E2), a boomerang-shaped rear wing (6), curving gibbously to the back, having a leading edge (6F), a trailing edge (6B) and the third and forth airfoil tips 86E1, 6E2), the first wing box (8L) connecting the first airfoil tip of the front wing and the third airfoil tip of the rear wing, the second wing box (8R) connecting the second airfoil tip of the front wing and the fourth airfoil tip of the rear wing. The trailing edge of the front wing, the leading edge of the rear wing, and the internal surfaces of the wing boxes form a center opening (9) having, at least in part, elliptical shape.
