AIRCRAFT NOZZLE

摘要

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.

主权项

1. An apparatus comprising:
an aircraft powerplant having a plurality of flow paths; a first flow path defined by a movable first flow path surface; and a second flow path radially outward of the first flow path and defined between a movable second flow path surface and a third flow path surface, the third flow path surface structured to move with movement of the movable first flow path surface.
