The invention provides a special spoon-shaped wing section with ultra-low Reynolds number, high lift-drag ratio and low speed. The thickness of the wing section before 60% of a chord is smaller and the thickness of the wing section after 60% of the chord is larger, so as to form a spoon shape geometry characteristic; the maximum relative thickness of the wing section before 60% of the chord is about 66% that of the wing section after 60% of the chord; the position of the maximum relative thickness of the wing section is at about 77% of the chord; the wing section has an area with reducing thickness at about 40% of the chord and the minimum relative thickness of the area of the wing section is about 35% of the maximum relative thickness of the wing section; the front part of the wing section is smaller in thickness and the rear part of the wing section is larger in thickness, so that the wing section has a good torque characteristic; under the Reynolds number of not greater than 10<4>, layer separation bubbles are small; the resistance of the wing section is greatly reduced, so that the wing section has a high lift-drag ratio and excellent pneumatic performance.
