ABSTRACT:
Improvements in orientable axisymmetric nozzles of variable geometry which are intended for gas turbine engines, which nozzles comprise a convergent zone (2) followed by a divergent zone (3), both formed by main petals (4-5) and secondary petals (33-34), and they add to the known functions (simultaneous axisymmetric variation, according to a preestablished law, of the throat area A8 and of the outlet area A9; variation of all the geometry of the outlet area A9 independently of the throat area A8; and, axisymmetric orientation of the flow) a fourth function of varying only a part of the geometry of the outlet area A9 independently of the throat area A8.
