This method of slot suction is used on different airfoils and with different flaps to enhance lift, but the suction volume involved is too high (1% Q <3%), and cannot be popularized for practical application
Even though surface and multi-slot suction are still considered valuable methods for maintaining laminar flow at high Reynolds numbers, airfoils thinned to reduce drag at high speeds make it necessary to remove low-pressure external fluids. Larger piping applications within the more restricted

Abstract

The invention belongs to the field of air chamber connection controllers and discloses an air chamber connection controller. The air chamber connection controller comprises a wing, as well as one or more air inlet holes, one or more air outlet holes, sealed air chambers and an air delivery driving device which are arranged on the wing, wherein the air inlet holes are formed in the leading edge area of the upper surface of the wing, and the forming direction of the air inlet holes is perpendicular to the upper surface; the air outlet holes are formed in the trailing edge area of the upper surface or/and the lower surface of the wing; and the sealed air chambers and the air delivery driving device are arranged in the wing and are connected with each other to form an air passage. The air chamber connection controller is practically applied to a wing profile of an independent entity; besides, the combination of slot suction with closed-loop control is used to provide lift force and reduce resistance; the air chamber connection controller is simple in structure; and industrialized production of the air chamber connection controller can be realized.

Description

technical field [0001] The invention relates to an air chamber connection controller. Background technique [0002] Delayed flow separation by steady suction was first started in 1904, when Prandtl demonstrated the theory of boundary layers, the rotational flow of the boundary layer was removed by narrow suction grooves located on the surface of the cylinder, thus in most of the cylinder The flow remains attached to the surface. Ackeret, Betz & Schrenk applied this idea to thick airfoils of the Joukowski type, reducing drag by delaying separation through the flow of suction, and was also cited by Lachmann. This method of slot suction is used on different airfoils and with different flaps to enhance lift, but the suction volume involved is too high (1% < C Q <3%), and cannot be popularized to practical applications. Even though surface and multi-slot suction are still considered valuable methods for maintaining laminar flow at high Reynolds numbers, airfoils thinned ...
