We have studied more than 40 different Tailless airfoils in search of the best performing stable airfoil.
The Flying-wing airfoil stability was derived from the first principles.
Based on the XFoil results the momentum coefficient was calculated at each point on the 2D space.
The position of the Aerodynamic Center (AC) and the Center of Pressure (CP) points were established and as a result the optimal position of the Center of Gravity (CG) point was chosen.


Tools I have used for this analysis can be trusted, please check my video on the Wind Tunnel data verification:    • The Wind Tunnel data vs XFOIL simulat...
