Orientable axisymmetric nozzle of variable geometry of gas turbine propulsors

摘要

Orientable axisymmetric nozzle of variable geometry for gas turbine engines which comprises convergent (2) and divergent (3) sections formed by master petals (4, 5) and slave petals (33, 34) duly connected together, each divergent master petal (5) being connected to an outer annular control part (6) by a biarticulated bar (15). This bar is connected by one end to the part (6) by a cylindrical articulation (16) while by its opposite end it is connected to the divergent master petal (5) via intermediate bars (26, 27).
