PURPOSE: To accomplish actions of decrease in wave making resistance, decrease in resistance with prevention of shock wave separation at a boundary layer, increase in lift, buffet prevention, etc., by providing a wing root rear edge whose chord length is progressively elongated when approaching the...
1.The W-shaped tailless aircraft has not stabilizer and vertical tail,and it is based on the design offorward-swept wingand the integrated design of blended wing-fuselage.W型无尾飞机基于前掠翼及翼身融合的一体化设计,取消了平尾和垂尾,可大幅降低雷达反射截面积,减轻结构重量;同时具有亚声速气动效率...

In particular the goal is to design a forward swept laminar wing having a design Mach number of 0.78 and the capability of reaching Mach 0.80 in high-speed off-design. The present paper gives an overview on the current status of the project as well as prospects for future work. 展开 ...
forward swept wing without weight penalty. The results obtained demonstratethat for the forward swept wing, the most violent situation appears around Mach Number 1.0 where the aeroelastictailoring optimization could decrease the torsion angle by nearly 70.0%. The torsion of forward swept wing will ...
