AI Technical Summary

Technical Problem

Existing airfoils experience issues with airflow separation and turbulence at the leading edge, leading to inefficient aerodynamic performance and increased drag.

Method used

The airfoil design incorporates a folded or solid geometry with specifically curved arc portions that utilize the Coand effect to actively control turbulent eddies and maintain airflow attachment, redirecting it through a large angle using a series of arcs and elliptic surfaces.

Benefits of technology

The design effectively stabilizes the airflow, preventing boundary layer separation and reducing drag by maintaining airflow attachment, allowing for efficient redirection of airflow by up to 90 degrees.
