A thrust reverser system for a turbine engine of the type having a central relatively hot gas generator nozzle conducting a core flow and a relatively cold duct conducting a fan flow and surrounding the hot flow, a pair of thrust reverser door, each of the doors being pivotally mounted on an axis which is substantially diametrically positioned with respect to the exhaust nozzle of the engine so as to pivot between a stowed position in which the doors are out of the direct path of exhaust from the engine and a deployed position in which the doors are in the path of the engine exhaust for deflecting the exhaust and creating a braking thrust, a flow modifying arrangement acting on the hot gas generator nozzle for simultaneously decreasing the total pressure of the core flow and increasing the total pressure of the fan flow by increasing the area of the hot gas generator nozzle at the discharge end thereof and moving the boundary between the hot gas and cold gas flows radially outwardly. |
