Airplane with a tailcoat tail assembly and rear engine

An airplane comprising:

• a fuselage including at least one wing attached to the fuselage between a front end and a rear end of the fuselage, the fuselage having a substantially cylindrical central part and a tapered rear part joined to the central part at a connecting section, onto which a vertical tail assembly is attached and onto which a rear propulsive assembly is attached substantially at a vertical symmetry plane of the fuselage,
• wherein, in the tapered rear part:
• a maximum height of each section of the fuselage decreases toward a rear of the airplane so that the rear end of the fuselage forms a trailing edge with a width L;
• a maximum width of each section of the fuselage increases continuously, the maximum width being locally constant or increasing toward the rear of the airplane, from a maximum width of the connection section up to the width L, the width L being greater than the maximum width of the connecting section;
• a rear engine of the rear propulsive assembly is situated in a rear part of the fuselage so that a lower part of the rear engine, at a maximum diameter of the rear engine, is partially inside the fuselage and an upper part of the rear engine is on top of the fuselage according to a semi-buried configuration;
• and
• the rear propulsive assembly includes a nacelle having shapes which join with the rear part of the fuselage on each side of the nacelle.
