High Angle Attack Airfoil
High Angle Attack Airfoil
(OP)
Looking for a subsonic cambered airfoil that has good lift at up to 15-20 degree angle of attack without stalling. Switch blade wings for use with delta lifting body. Need to enhance lift during lift-off, landings and subsonic glide.

Check NASA TM X-74018 ( ABOUT LS (1)- 0413 AIRFOIL ). This
airfoil may fullfill your requirements and the information can be downloaded free from NASA technical server.
Cheers

Found the pdf file of that report. Will take sometime to absorb it. I'm more familiar with NACA airfoils, I assume the LS (1)-0413 is based on the Whitcomb supercritical design? The C-17A transport uses a supercritical airfoil. Something similar may work well in my application.

if they pivoted (like the h.stab. on most jets today, or like the tail-booms on burt's space-craft) that would increase the AoA range on a reasonably conventional airfoil.
to me high AoA means large L/E radius which is probably inconsistent with efficient flight at reasonable Mach numbers.
