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

AI Thread Summary
Post-stall airfoil data is challenging to find, particularly for high angles of attack, as traditional lift coefficient metrics become invalid once an airfoil stalls. Instead, the airfoil behaves more like a drogue, and drag can be modeled based on its cross-section relative to the airflow. Resources such as specialized textbooks or dedicated aerodynamics websites may provide some insights, but comprehensive data is limited. Understanding the transition from lift to drag is crucial for accurate modeling in numerical methods programs. Exploring advanced aerodynamics literature may yield the necessary information for post-stall conditions.

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the drag based on it's cross section with respect to the incident airflow, but the concept of a lift coefficient is no longer valid.

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
