The invention discloses a fusion body layout large civil airliner. Wing and fuselage fusion and V-shaped double-vertical-fin layout are adopted. Four turbofans are assembled, wherein the two turbofansare hung below the wings and the two turbofans are carried at the rear part of the fusion body. Between the V-shaped double vertical fins, on the premise that the internal volume of the fuselage is the same, compared with the conventional layout, the infiltration area of the wing and fuselage fusion layout is reduced by 1/3; therefore, frictional resistance can be greatly reduced, besides, the chord ratio of the wing and fuselage fusion layout is large; the corresponding induction resistance is relatively low; according to estimation, the cruise lift-drag ratio of the wing-fuselage integratedairliner at least exceeds 23, the aerodynamic efficiency is far higher than that of a conventional layout airliner, the two turbofans are arranged on the rear upper portion of the fuselage, the noiseof the turbofans cannot be reflected to the ground by wings like the conventional layout airliner, the V-shaped empennage and the rear airliner also play a good role in shielding, and the noise levelis far lower than that of the layout of four wing-hung engines.

    本发明公开了一种融合体布局大型民用客机,采用翼身融合、V形双垂尾布局,配装四台涡扇发动机,两台吊挂于机翼下方,两台背负于融合体后部,V形双垂尾之间,在机体内部容积相同的前提下,翼身融合布局的浸润面积相对于常规布局减少了1/3,从而可以大幅减少摩擦阻力,此外,翼身融合布局的展弦比较大,相应的诱导阻力也较低,据估算,翼身融合客机的巡航升阻比至少将超过23,气动效率远高于常规布局客机,两台发动机被置于机体的后上部,发动机噪声不会像常规布局客机那样被机翼反射到地面,而且V形尾翼和后机身也起到了很好的屏蔽作用,噪声等级远小于四台翼吊发动机布局。
