DOI: 10.1063/5.0025327
Abstract: The leading-edge-suction-parameter modulated discrete vortex method is extended to a wing with a finite span and no sweep, in order to get the development of aerodynamic coefficients with an angle-of-attack, from attached to completely detached… read more here.

DOI: 10.1177/09544100221100057
Abstract: The flow separation over a very flexible or morphing aircraft, especially during flying or oscillation at a high angle of attack, is stronger than that for conventional aircraft. However, a low-order model for reliably predicting… read more here.
