Hi,
Good stalling performance doesn't have sharply reduced lift coefficient after AoA enters stalling range. This is preferred for the safety reason. Some designs have good stalling performance, some not.
I'm wondering how do GA company predict the stalling performance of the aircraft before the flight test?
CFD is not able to well predict the stalling performance as the 2 equations model is weak for the boundary layer separation prediction. Wind tunnel is usually expensive and may not be able to predict it either. Then how do GA company design good stalling performance aircraft? What are the typical designing method and process for this?
