Abstract
A nozzle for an aircraft powerplant is disclosed which provides two separate flow paths. A flow path is provided in the nozzle for a core flow of the powerplant and another flow path is provided for a bypass flow of the powerplant. The nozzle can have a variety of configurations including, but not limited to, 2D and axisymmetric. Either or both the flow paths can be convergent, divergent, or convergent-divergent, and the flow paths need not be similar between the two. Actuators are provided to manipulate the configuration of the flow paths and the areas of the flow paths. For example, throat and/or exit areas can be manipulated.
