The double-bubble fuselage aircraft configuration is a suitable aircraft concept for achieving higher environmental performance. This study aims to improve the aerodynamic performance of the fuselage geometry design of a double-bubble aircraft configuration (JAXA's technology reference aircraft, TRA2035A). In this regard, to understand the aerodynamics of the fuselage geometry, CFD analyses were conducted considering several geometric parameters, such as the height and length of the nose and tail parts. The parametric studies regarding only the fuselage geometry showed that higher nose and lower tail positions improved the lift-to-drag ratio and reduced the trim drag by nose-up pitching moment. Therefore, the fuselage geometry of a wing-body configuration was re-designed. The re-designed geometry showed a higher aerodynamic performance than a baseline geometry. Moreover, the aerodynamics of the wing-body configuration exhibited the same trend as that of the fuselage-only configuration.
