Abstract (en)
The variable geometry nozzle has outer and inner boundaries of an annular nozzle passage defined respectively by flaring surface formed internally in a female element (26) and a tapering surface formed externally on a male element (22) located within the female element (26) The element (22) is adjustable axially relative to element (26) from a first position to a second position to increase the cross-sectional area of the throat of said nozzle passageway progressively, said boundaries being shaped to diverge from the throat to the exit when the male element (22) is in the first position and to be parallel when the male (22) element is in the second position.
