Adjustable turbomachine stage

摘要

The stage has a sectored internal rim (12) carrying a sectored annular ferrule (46) provided with an annular rib. Sectors of the internal rim comprise axial orifices for mounting radial retention pins (70, 76) on an internal pivot of a vane (10). Each pin has a head provided with an immobilizing unit. The immobilizing unit has a finger (72) cooperating with a notch (78) for immobilizing the pin in the orifice. The head has an indication unit indicating an angular position of the notch on a body of the pin for avoiding bad mounting of the pin in the orifice.
