ABSTRACT:
A divergent master petal for orientable nozzles of variable geometry intended for gas turbine engines, which is connected by means of articulations to the convergent master petal (4) and to a bar (12) which connects the master petal to the control mechanism. The inner surface (5c) of the divergent master petal (5), which is in contact with the flow of gases, is of variable shape between a substantially straight cross section coinciding with or close to the upstream transverse edge and a convexly curved cross section coinciding with or next to its downstream end transverse edge, with the convexity directed towards the inside of the engine.
