Where to find post stall airfoil data for high angles of attack

[Antonio9393]

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the drag based on it's cross section with respect to the incident airflow, but the concept of a lift coefficient is no longer valid.
