A supersonic aircraft includes an internal passageway, an articulated intake structure and an articulated exhaust structure which is connected to the intake structure by the passageway. The articulated intake structure defines an opening having a cross-section which is essentially equal to the cross-section of the aircraft's fuselage when configured for supersonic flight and smaller opening when configured for subsonic flight. Also, for supersonic flight, the cross-sectional area of the air intake structure decreases in the direction of air flow. For subsonic flight, the cross-sectional area of the air intake structure is relatively constant. For supersonic flight, the exhaust structure defines a cross-section which increases in the direction of air flow.
