AI Technical Summary
Technical Problem
Existing aeronautical propellers, particularly those with unducted rotors, face issues with noise generation, mechanical performance, and aerodynamic efficiency, which can also impact global warming.
Method used
The propeller design incorporates undulated trailing and leading edges on the blades, along with variable pitch mechanisms, and optimized pitch and skeleton angles to control airflow, combined with a speed reduction system to improve aerodynamic performance and reduce noise.
Benefits of technology
The design enhances aerodynamic efficiency, reduces noise, and improves mechanical strength while minimizing the impact on the environment by optimizing airflow dynamics and reducing acoustic radiation.
