Discover Post Stall Airfoil Data for High-Angle-of-Attack Calculations

Click For Summary
SUMMARY

The discussion centers on the search for post-stall airfoil data, specifically lift coefficient data for airfoils at high angles of attack. A participant highlights that once an airfoil stalls, it transitions to a drogue, rendering the lift coefficient concept invalid. The need for reliable data sources, such as books or websites, is emphasized for those developing numerical methods programs in aerodynamics.

PREREQUISITES
  • Understanding of aerodynamics principles, particularly lift and drag forces.
  • Familiarity with numerical methods in computational fluid dynamics.
  • Knowledge of airfoil design and performance characteristics.
  • Experience with data analysis and interpretation in aerodynamics contexts.
NEXT STEPS
  • Research sources for post-stall airfoil data, including academic journals and aerodynamics databases.
  • Explore computational fluid dynamics (CFD) software for simulating high-angle-of-attack scenarios.
  • Study the transition of airfoil behavior from lift generation to drag dominance during stall.
  • Learn about the modeling of drag based on cross-sectional geometry in aerodynamics.
USEFUL FOR

Aerodynamic engineers, researchers in fluid dynamics, and developers of numerical methods programs focused on high-angle-of-attack airfoil performance.

Hello all,

Where can I find post stall airfoil data? I'm writing a numerical methods program and need lift coefficient data for airfoils at very high angles of attack. Books or websites would be great.

Thank you for any help

Once the airfoil has stalled it ceases to be an airfoil and becomes a drogue. You can model the drag based on it's cross section with respect to the incident airflow, but the concept of a lift coefficient is no longer valid.
