Three fuselage aircraft comprises central fuselage and two lateral fuselages connected by two longitudinally separated lift surfaces comprising two fixed aerofoils

摘要

The aircraft has a central fuselage (1) and two lateral fuselages (2,2') connected by two longitudinally separated lift surfaces each comprising two fixed aerofoils extending between the central fuselage and each lateral fuselage. The two front fixed aerofoils (30,30') and the two fixed central aerofoils (40,40') have leading edges (41,41') inclined symmetrically at a sweep angle of at least 40o. The surface of each free space (12) between the trailing edge (32) of a front fixed aerofoil and the leading edge (41) of the central aerofoil which follows it is of the same order as the surface covered by the front aerofoil.
