[0047] The invention has upper camber (6), middle camber (7) and lower camber (8) with a positive torsional angle of 15° counterclockwise at the rate of increase in linear velocity from the bottom to the tip. The product of the present invention includes the mean camber (7), which is positioned at the same angle parallel to the upper camber (6) and the lower camber (8). The invention has a pointy structure of mean camber (7) with leading edge of mean camber (H.sub.2) and trailing edge of mean camber (F.sub.2). The invention has a middle beam (5) positioned in parallel between each other between the upper camber (6) and the lower camber (8). The invention preferably includes a circular cross-section and a root (2) fixed to the root end (3) associated with the upper camber (6), the mean camber (7) and the lower camber (8), depending on the bearing structure fixed on the hub (1). The root (2) has a structure that can rotate 360° around itself.

[0048] The invention has a maximum lower camber (8) thickness at 18% of profile length and 40% of chord length. The system subject to the invention has a 3-wing profile structure that creates an air tunnel by providing the air flow in a linear way. The product of the invention includes an upper camber (6) and lower camber (8) having a structure that narrows from the bottom to the tip. The upper/lower camber (6) and lower camber (8) bottom/tip ratio is 2.13. The root (2) of the invention has a wedge that allows the wing to be fixed at the desired angle. The invention has electronic control and monitoring system. The invention has upper camber (6), mean camber (7) and lower camber (8), which can be manufactured with a composite structure optionally formed by glass, carbon fiber and kevlar materials. The invention has upper camber (6), mean camber (7) and lower camber (8) optionally manufactured from ABS or PLA materials.

[0049] The present invention is comprised of hub (1), root (2), root end (3), tip end (4), middle beam (5), upper camber (6), mean camber (7), lower camber (8). The upper camber (6) of the invention has the surface S.sub.1 (6.1). The lower camber (8) includes surface S.sub.2 (8.1), surface S.sub.3 (8.2), surface S.sub.4 (8.3) and surface S.sub.5 (8.4).

[0050] Upper camber (6), mean camber (7) and lower camber (8) in the invention are produced in one piece. Each wing; the connecting cage is attached to the middle table (1) with nuts and bolts. With the wedge located in the parts of the handle (2), the wings are prevented from turning around their own axis. After mounting the blades to the hub (1), the threaded shaft housing located in the middle of the hub (1) is seated on the reducer shaft. The wedge belonging to the reducer shaft is placed and tightened with a top cover and bolt.

[0051] The upper camber (6) has a Clark Y-type wing profile. The middle camber (7) has geo 445 airfoil (geo-445 province) profile. The lower camber (8) is combined with the upper surface of the boeing 707.08 span (b) lower surface with the roncz 1080 voyager inner aft wind airfoil (r1080-il) profiles. The maximum thickness is at the 18% point of the profile and 40% chord length. The name of the new profile is GT Profile.

[0052] The working principle of the product according to the invention is as follows; the air entering the system is divided into two on the leading edge of upper camber (H.sub.1) of the upper wing and distributed to the upper and lower surfaces. The upper surface of the upper camber (6) provides the air to be swept upwards and this air is removed from the system. On the bottom surface, air accelerates, air pressure drops and moves linearly in the tunnel. The middle camber (7) prevents turbulence by hitting the air entering the tunnel to its upper and lower surfaces. Thanks to the trailing edge of mean camber (F.sub.2) of the mean camber (7) being pointed (trailing edge of 1 mm), it allows the air to leave the tunnel quietly. The air entering the system is also divided into two on the leading edge of lover camber (H.sub.3) of the lower camber (8). The pressure of the air accelerating on the lower surface of the lower camber (8) decreases on the surface of S.sub.4 (8.3) and the pressure increases on the upper surface by reaching the surface S.sub.2 (8.1). Force is generated towards the lower surface, which has a low pressure. In this part, the air moves out of the tunnel linearly with high pressure. The volume and pressure of the fluid reaching the S.sub.3 point (8.2) increases suddenly and the speed decreases. In this way, the wing exerts force in the opposite direction. This force positively affects the wing in the direction of rotation.

[0053] The values of a fan currently used with our system subject to our invention have been measured using calibrated devices, and the actual values have been specified below in Table-1 and Table-2. In the measurement method, the actual values of the currently used aluminum fan are measured. Then, the aluminum fan was removed from its place and the product subject to our invention was replaced and the measurement was made again under the same ambient conditions. In addition, the analysis of the mass characteristics of the aluminum fan blade and our product according to the invention are given below using computer program analysis (ANSYS, XFLOW).

n=((122,93*8,39*543)/(1000*51,20))/100=%10.94 efficiency of the fan

n=((143,917*13,99*550)/(1000*11,95))/100=%92.67 efficiency of the fan

[0093] As can be seen from the tables above, our invention's wing profile structure designed with aerodynamic calculations and the fact that the wing consists of a triple wing profile increased the volume of air passing through the wings per unit time, significantly increasing the efficiency and reducing the amount of energy it consumes.
