Aircraft with boundary layer ingestion device having center position between center position of fuselage and center position of rear end portion of fuselage

An aircraft, comprising:

• a fuselage section that has a cylindrical shape with a first predetermined length in an axial direction and a second predetermined length in a width direction and a vertical direction, and includes a rear end portion on a rear side in the axial direction, wherein the first predetermined length is longer than the second predetermined length, wherein the fuselage section has a shape in which an outer diameter gradually decreases toward the rear end portion on the rear side, wherein a center position of the rear end portion is located above a center position of the fuselage section at a position corresponding to a maximum diameter of the fuselage section in the vertical direction;
• and
• a boundary layer ingestion (BLI) propulsion device that is provided on the rear side of the fuselage section and includes an intake port, wherein a center position of the intake port is located between the center position of the fuselage section and the center position of the rear end portion in the vertical direction, and wherein the center position of the intake port is offset below the center position of the rear end portion in the vertical direction,
• wherein the BLI propulsion device includes at least one impeller that is rotatable with an axis directed in the axial direction as a central axis, and
• wherein a position of the central axis is offset above the center position of the intake port in the vertical direction.
