A near supersonic aircraft comprising an airframe that maintains subsonic air flow thereover within the flight envelope of the aircraft. The airframe comprises a right circular conical forward fuselage section, a right circular cylindrical intermediate fuselage section defining a passenger compartment, and an aft fuselage section having a generally circular frontal cross section and a generally rectangular aft cross section. A submerged semi circular air inlet is disposed between the intermediate and aft fuselage sections at the top thereof. A pair of forwardly swept wings are joined to the fuselage adjacent the circumferentially spaced ends of the air inlet whereby air flow over the fuselage and along the leading edges of the wings is directed into the air inlets at subsonic speeds and at all attitudes of the aircraft within its flight envelope.

A near supersonic aircraft having an airframe configuration that maintains subsonic air flow thereover within the flight envelope of the aircraft comprising a forward fuselage section comprising a right circular cone having a single axis of generation, an intermediate fuselage section defining a passenger compartment and comprising a right circular cylinder the central axis of which defines the longitudinal axis of said aircraft, the axis of generation of said forward section being orientated at a small angle forwardly and downwardly relative to the longitudinal axis of the intermediate fuselage section, a first transition section between said forward and intermediate fuselage sections comprising a non-developable surface smoothly transcending from a generally elliptical cross section at the aft end of said forward fuselage section to a circular cross section at the forward end of said intermediate fuselage section, an aft fuselage section having a generally circular frontal cross section and a generally rectangular aft cross section, a second fuselage transition section between said intermediate fuselage section and said aft fuselage section having a circular frontal cross section complementary to the intermediate fuselage cross section and being necked down at the aft end thereof through an arc of approximately 180°to a diameter less than the diameter, of said intermediate fuselage section, a semi circular engine air inlet disposed adjacent the junction of said second transition section and said aft fuselage sections at the top thereof, and a pair of forwardly swept wings having leading edges joined to said fuselage adjacent the circumferentially spaced ends of said air inlet whereby air flow over said fuselage and along the leading edges of said wings is directed into said air inlet at all attitudes of said aircraft within its flight envelope.
