I was wondering how AOA is defined in VSP, is it the angle between the free stream and the X axis or something different?
I am running a VLM analysis on the HSTAB of a transport category jet and
using VLM to evaluate the effect of elevator deflection. The
analysis is being done at a Re of 22.7M and Mach 0.23 (Sea level ISA).
The max CL AOAs results seem very high for a transonic airfoil. Since the airfoil is inverted the negative AOAs would be the same as the upright case. Any insight is appreciated!
