Abstract:
1. An apparatus, comprising: a nozzle defining a passage to receive and discharge working fluid to produce thrust, the nozzle including a first wall structure opposite a second wall structure, the first wall structure including a first convergent flap pivotally connected to a first divergent flap, the second wall structure including a second convergent flap pivotally connected to a second divergent flap, the first wall structure and the second wall structure defining a throat along the passage and being reconfigurable to adjust distance across the passage at the throat; and one or more control valves located within at least one of the first convergent flap and the second convergent flap to modulate flow of a pressurized fluid into the passage through a first opening in the first wall structure and a second opening in the second wall structure proximate to the throat to change effective size of the throat by fluidic control.
