GAW-1两段翼开缝气动特性的影响分析
Investigation on the influence of aerodynamic characteristics of GAW-1 two-element airfoil with slot
摘要
Abstract
As a passive flow control technology,airfoil slotting has the characteristics of simple structure and high efficiency in improving stall.CFD method is used to study the slotting of GAW-1 two-element airfoil to explore the influence of slot parameters on the aerodynamic characteristics of multi-element airfoil.Nine kinds of slot config-urations are designed,and the geometric relations among three types of slot configurations,namely straight line,curve and deflector,are given,and a curved trapezoidal slot configuration is proposed.The influence of the deflec-tor slot configuration on the aerodynamic characteristics of the airfoil is studied.The results show that the slot posi-tion is the key factor to restrain the stall development of airfoil,and the optimal slot position of curved trapezoidal slot configuration is 13.5%c.The slot has the strongest ability to restrain stall,the stall angle of attack of airfoil is delayed by 7°,and the maximum lift coefficient is increased by 19.5%,reaching 3.89.The deflector slot configura-tion can not only weaken the damage of the slot to the aerodynamic characteristics at a small angle of attack,but al-so slow down the stall development and improve the stall characteristics of the airfoil.关键词
