Deformable flap with enhanced blowing-suction synergistic high lift force

Abstract

The invention provides a deformable flap with enhanced blowing-suction synergistic high lift force. The deformable flap comprises a wing composed of a leading edge flap, a wing body and a trailing edge deformable flap, wherein a jet flow cabin is arranged in the leading edge flap, and jet flow holes connected with the jet flow cabin are formed in the upper surface of the leading edge flap; a flow suction cabin is arranged in the trailing edge deformation flap, and flow suction holes connected with the flow suction cabin are formed in the upper surface of the trailing edge deformation flap; and a micro compressor is embedded in the wing body, is respectively connected with the jet flow cabin and the flow suction cabin through rubber pipes, and sucks air flow from the flow suction holes, pressurizes the air flow and then ejects the air flow from the jet flow holes. According to the invention, a blowing-suction synergistic active flow control technology is combined with the deformation flap, and the flap is used for a large fixed-wing aircraft, so a high lift enhancement effect is generated, take-off and landing aerodynamic characteristics are improved, short-distance take-off and landing are realized, airport pressure is relieved, cruising efficiency can be improved, and voyage can be increased.

Description

technical field [0001] The invention relates to the field of aerospace vehicles, in particular to a deformed flap with blowing and suction synergistic high-lift enhancement. Background technique [0002] The wing is the main component of the aircraft to generate lift, and taking measures to increase the lift of the wing is an important technology to improve the take-off and landing performance of the aircraft. Conventional mechanical lift devices increase the lift at the cost of increasing the complexity of the mechanism and the weight of the structure. At present, it is difficult to further increase the lift and improve the take-off and landing performance. [0003] From the perspective of reducing structural weight and reducing maintenance costs, the lifting device should be simple and reliable. The development direction of the future wing is a complete, self-adaptive intelligent wing, where "complete" refers to the fact that the surface of the wing has no hinges and no g...

Problems solved by technology

Existing studies on blow-suction synergistic flow control mainly focus on single-section airfoils or wings. Preliminary research results show that blow-suction synergy can produce supercirculation effects and significantly increase lift and stall angle of attack. However, the larger lift coefficient needs to be at It can only be realized at a very large angle of attack. This problem greatly limits the application of blow-suction cooperative flow control on large aircraft, and further research and solutions are needed.
