Abstract

The invention discloses an aircraft lift force optimizing system which comprises a blunt trailing edge wing, a set of dielectric barrier discharge plasma exciters and a power supply. The circulation control cost-effectiveness of the system can reach 108 which is far higher than the maximum value 80 of traditional circulation control, energy consumption is low, an optimized key parameter combination can increase the effective inflow velocity to 35 m/s, the generated Coanda effect is more obvious, the circulation and lift force change is more obvious, and the system is suitable for popularization.

Description

technical field [0001] The present invention relates to the technical field of aircraft lift, and more specifically, relates to an aircraft lift optimization system. Background technique [0002] Improving the lift of aircraft is one of the important goals of aircraft design. At present, the development of mechanical lift systems represented by flaps, ailerons and various slats is relatively mature, but the increase in moving parts will increase the weight of the aircraft, complicate the structure, increase the difficulty of maintenance and maintenance costs, especially for the new generation of military aircraft In terms of radar reflection sources such as sharp edge openings and protrusions formed by many control surfaces, the stealth performance of the aircraft is greatly reduced. [0003] The Coanda effect is also known as the wall attachment or the Coanda effect. The fluid (water flow or air flow) tends to deviate from the original flow direction and flow along the su...
