Abstract

The invention relates to an aircraft comprising a lift-producing fuselage (1 ) whose largest span (11) lies in the middle third (14) of the total length an d whose horizontal projection progressively diminishes in the front third (13) and in the rear third (15). The aircraft also comprises two wings (2), where by the surface of the projection of both wings represents, in a horizontal plan e, less than thirty percent of the total lift surface, and the wings are locate d in the middle third (14) of the total length of the fuselage. The aircraft additionally comprises a horizontal tail unit (4) situated in the rear third of the fuselage. The aircraft has a shape similar to that of a fish.
