AI Technical Summary

Technical Problem

The misalignment of sectors in a turbine distributor of an aircraft turbomachine leads to inefficiencies due to non-homogeneous cross-sections and flow disturbances, which are difficult to correct during manufacturing and cannot be adjusted post-assembly, impacting turbomachine efficiency.

Method used

The implementation of variable pitch blades with adjustable pitch angles allows for homogenization of the passage section by adjusting the blades' pitch, enabling optimization throughout the engine's lifetime.

Benefits of technology

This adjustment enhances turbomachine efficiency by homogenizing the passage section, allowing for improved performance during assembly, maintenance, and operation.
