PROPELLER FOR AN AIRCRAFT TURBOMACHINE, INCLUDING A BLADE RETAINING STRUCTURE THROUGH WHICH THE AERODYNAMIC PART OF EACH BLADE PASSES

摘要

A propeller for a turbomachine intended to be driven in rotation about a propeller rotation axis and including variable pitch blades. The propeller further includes a structure for radial retention of the blades in the event of them breaking. The retaining structure extends around the propeller rotation axis and has the aerodynamic part of each blade of the propeller pass through it. Moreover, each aerodynamic part is equipped with an abutment configured to be retained radially by the retaining structure in the event of a blade fracture causing a fracture in the aerodynamic part radially inside the abutment.

1. A propeller for a turbomachine intended to be driven in rotation about a propeller rotation axis and including variable pitch blades, each blade comprising a root and an aerodynamic part, comprising:
a structure for radial retention of the blades in the event of them breaking, said retaining structure extending around the propeller rotation axis and having the aerodynamic part of each blade of the propeller pass through it, and each aerodynamic part being equipped with an abutment configured to be retained radially by the retaining structure in the event of a blade fracture causing a fracture in the aerodynamic part radially inside said abutment.
