Abstract: An aircraft comprises a fuselage, wings extending from the fuselage, and engine nacelles, wherein the fuselage has contours shaped to create shock and expansion zones to compensate for expansion zones and shocks produced by the wings and engine nacelles when the aircraft travels at supersonic speeds. The fuselage shape can be achieved by including a main fairing positioned along a bottom surface of the fuselage. The nacelles can be positioned adjacent to the fuselage and integral with the wings, and the aircraft can further include auxiliary fairings positioned along bottom surfaces of the nacelles.
