Abstract:
A multirotor aircraft that includes a chassis, at least three engines that equipped with propellers, and a free wing that is axially connected to the chassis. The attack angle of the free wing is changed relatively to the chassis due to flow of air. When the aircraft is hovering then the free wing is free to rotate, when wind flows over the wing during hovering then the tilt angle of the wing is changed by forces of the wind to a position in which a drag force on the wing is reduced, and by that enables a precise hovering relative to a ground point and precise control over the aircraft. The free wing provides lift force in horizontal flight and in situations of front horizontal wind during hovering and by that reducing the amount of energy required to operate the aircraft.

Claim (Index 5):
A multirotor aircraft that comprises a chassis, at least three engines that each of them is equipped with a propeller, and at least one axial free wing; wherein the axial free wing is connected to the chassis by an axial connection; wherein an attack angle of the axial free wing is designed to be changed relatively to the chassis due to flow of air over said axial free wing;\n wherein when said multirotor aircraft is in hovering stage the axial free wing is designed to be free to rotate axially on said axial connection; wherein when wind flows over said axial free wing during hovering then the tilt angle of the axial free wing is changed by forces of said wind to a position in which a drag force on said axial free wing is reduced; whereby the reducing of said drag enabling a precise hovering relative to a ground point and enabling precise control over the multirotor aircraft; wherein the axial free wing is designed to provide lift force in horizontal flight and in situations of front horizontal wind during hovering whereby reducing the amount of energy required to operate said multirotor aircraft.
