1. , for having an engine compartment assembly for the turbofan jet motor of engine centerline, described engine compartment comprises:

  • A () has the fixing forward direction engine compartment portion of outer rectifying device and trailing edge;

    B () comprises the translational variable cross section fan nozzle of two or more spray nozzle parts, each spray nozzle part has relative first end and the second end, and relative to described engine centerline with the outside and sweptback leading edge of the first angle, described fan nozzle is alternative mobile between stowed position and one or more expanded position, when being wherein in described expanded position, form upstream bypass flow outlet between edge and leading edge in the rear;

    WithC () comprises the castor tail formula that the is separated rectifying device in the upstream rectifying device section on outer rectifying device and the rectifying device portion, downstream at least one end of at least one spray nozzle part;

    D (), wherein when at least one spray nozzle part described is in stowed position, described upstream rectifying device section and rectifying device portion, described downstream are combined to form the roughly continuous print outer surface extended between described outer rectifying device and at least one spray nozzle part described;

    AndE () is wherein when at least one spray nozzle part described is in expanded position, described upstream rectifying device section and rectifying device portion, described downstream are limited to the elongate slot roughly extended back therebetween, described elongate slot relative to described engine centerline with the second angular slope.
