Abstract:
1. A wing comprising: a lower portion that is located between two curved portions of the wing; wherein the lower portion is substantially flat and the two curved portions of the wing extend above the lower portion; wherein the wing is arranged to support multiple engines that rotate multiple propellers, each propeller of the multiple propellers is more proximate to a trailing edge of the wing than to a leading edge of the wing and is arranged to introduce a quasi-laminar stream when positioned in proximity to the trailing edge of the wing and is circulated at a desired speed; wherein the wing partially surrounds a space that is wider than twice a diameter of each propeller out of the multiple propellers, wherein a tip trajectory of each propeller of the multiple propellers at least partially overlaps the space; and multiple shrouds, each shroud being located above a propeller of the multiple propellers and partially surrounds the propeller; wherein a combination of the lower portion of the wing and the shroud substantially surrounds the propeller.
