Novel wing profile for aircraft.

Abstract

2.1. Known aircraft wing profiles resemble an elongated teardrop shape. They are thickest at the leading edge and taper towards the trailing edge. Consequently, their frontal areas are large. The resulting high drag reduces thrust. Since this also significantly decreases the speed of the air flowing over the wing surfaces, the lift potential of these wing profiles is limited. 2.2. The object of the invention is to create a novel airfoil that increases the speed of aircraft, enhances their lift, and reduces their fuel consumption. This is achieved by shifting the greatest wing thickness from the leading edge to the trailing edge. This allows the upper and lower surfaces of the wing to converge at the leading edge in a pointed shape, thus minimizing airflow resistance. This shape also enables the airflow to be divided into upper and lower airflows surrounding the wing surfaces without turbulence or loss, thereby optimally increasing the wing's lift. The lower airflow is further enhanced by the steep, rearward-sloping lower wing surface, which compresses it more than conventional airfoils.Towards the wingtip, the high overpressure below the wing merges with the underpressure above the wing. This occurs very powerfully in the form of pressure equalization, and the rounded, upward-sloping underside of the wing generates a further pressure impulse in the direction of flight. 2.3. The installation of this novel airfoil is suitable for all aircraft as well as for rotor blades of helicopters and wind turbines. Due to the performance improvements, aircraft equipped in this way can fly faster and higher with less fuel consumption than previously possible. When used in the form of rotor blades on helicopters and wind turbines, they significantly and sustainably increase efficiency.

Description

[0001] The invention relates to a novel wing profile for aircraft, which can also be used in rotor blades of helicopters and wind turbines.

[0002] Due to climate change, it is necessary to make structural changes to aircraft wing profiles. To meet some of these requirements, it is known that wing profiles can be improved through gradual modifications.

[0003] Common wing profiles resemble elongated teardrops that taper toward their ends. This shape results in large frontal areas. This significantly slows down the propulsion of aircraft. Since this also slows down the air flowing around the sides of the wing, the lift forces are not optimal.

[0004] The invention is based on the object of creating a novel wing profile that increases the speed of aircraft, enhances their lift and improves their fuel consumption.

[0005] This object is achieved according to the invention by a novel wing profile for aircraft according to claim 1.

[0006] The advantages achieved with the invention lie in the fact that a new wing profile is created by shifting the greatest wing thickness from the front to the rear of the wing. This makes it possible to bring the upper and lower surfaces of the wing together at the front in a tip-like manner, whereby the air flow is only minimally slowed down. This shape also makes it possible to divide the air flow into an upper and lower air flow that surrounds the sides of the wing without creating any turbulence and thus with no losses, thereby optimally increasing the wing's lift force. Because the lower air flow is compressed more strongly than with conventional wing profiles by the steep, diagonally rearward lower side of the wing, the wing's lift force is increased even further. Towards the end of the wing, the high overpressure created below the wing combines with the negative pressure above the wing.This occurs very powerfully in the form of a pressure equalization and ensures a further pressure impulse in the direction of flight due to the rounded, upward-facing underside of the wing.

[0007] Due to the performance improvements, aircraft equipped with these innovative wing profiles can fly faster and higher than previously possible while using less fuel. When used in the form of rotor blades on helicopters and wind turbines, they significantly increase efficiency.

[0008] An embodiment of the invention is shown in the drawing. It shows Fig. 1 Novel wing profile for aircraft.

Claims

[1] Novel wing profile for aircraft according to claim 1, characterized by that by shifting the greatest wing thickness to the rear wing area, a new wing shape is created which consists of a convex-shaped, rearwardly inclined upper wing surface (1) and a wing underside (2), which are both brought together in a tip-like manner at the wing front side (3), whereby the straight part (4) of the wing underside (2) runs diagonally downwards to the rear, is continued in a rounded form (5) in the area of the greatest wing thickness and is united with the wing upper side (1) at the wing end (6) in an upward direction.
