    Patent number: 3955782
    Abstract: A gas turbine turbojet engine for a supersonic aircraft which fits into a nacelle having a substantially square cross-section. Air flow passing between the square section of the nacelle and the circular section of the engine is compressed by an auxiliary compressor driven by a compressor of the turbojet. The auxiliary compressor is housed within a diameter not greater than the maximum diameter of the turbojet, thus enhancing the engine performance particularly at take-off.
