Problems solved by technology

[0002] The wingspan of the prior art is flat, especially the lower surface of the wing is flat and straight, so the lift generated is small, accounting for 1 / 3 of the total lift, the aerodynamic utilization rate of the wings of the prior art is low, and the required wing area is relatively large
[0003] The wind blades in the wind power generation equipment in the prior art are in the shape of flat strips, the utilization rate of wind force is low, and the power generation in the effective wind force area is small

Abstract

The invention relates to the technical field of wings, and especially provides a narrow groove wing which has the features of shallow and wide front end and deep and narrow tail end. The size of a first wind inlet is larger than that of a first wind outlet. Compared with conventional wings, the total lift force of a composite-type wing is higher than a wing in the prior art by 70%, so that carrying capacity of an airplane is increased. The lower surface of the composite-type wing is composed of a plurality of such narrow groove wings, so that upward reverse airflow is not generated basically if the angle of attack is not large, and great inhibition effect on wingtip vortex is achieved, thereby reducing the induced drag of the air plane. In addition, 2 / 3 of the lift force of the composite-type wing is supplied by the lower surfaces of the narrow groove wings, so that damage of stall on airplanes is greatly reduced, thereby improving safety of the airplane. A narrow groove blade has thesame principle of the narrow groove wing and is high in utilization rate on wind power, so that on the basis of equal power generation quantity, the narrow groove blade can generate wind power electricity by three times as that with strip-shaped blades in the prior art.

Description

technical field [0001] The invention relates to the technical field of wings, in particular to a slotted wing, a composite wing and a slotted blade thereof. Background technique [0002] The wing in the prior art is flat in span, especially the lower surface of the wing is flat and straight, which produces little lift, accounting for 1 / 3 of the total lift. The aerodynamic utilization of the wing in the prior art is low, and the required wing area is relatively large. [0003] The wind blades in the prior art wind power generation equipment are in the shape of flat strips, the utilization rate of wind force is low, and the power generation capacity in the effective wind force area is small. Contents of the invention [0004] Aiming at the problems in the prior art, the invention provides a slotted airfoil with high utilization rate of aerodynamic force, a composite airfoil and a slotted blade with high utilization rate of wind force. [0005] In order to solve the above te...
