The oval and box wing retain zero losses at the wingtips and their induced drag of the entire aircraft (37% of total air resistance), regardless of whether the airfoil is conventional or thin quasi-airfoil. Innovative designs based on the presented innovations can double the efficiency, regardless of whether it is a flying machine with batteries, hydrogen, hybrid propulsion or only with combustion engines. The innovations are universal and radically change the wings and overall aircraft architecture. Whether they are vertical take off and landing or cruise or combined. Including having fixed wings and fixed engines, with the transition from vertical to horizontal flight and vice versa being done by aerodynamic rudders. They accelerate the air flow above them, reduce the air pressure there and therefore further increase the lifting force.
