Effects of angle of attack and vertical fin on transonic flutter characteristics of an arrow-wing configuration [PDF]
Experimental transonic flutter results are presented for a simplified 1/50 size, aspect ratio 1.77, wind tunnel model of an arrow wing design. Flutter results are presented for two configurations; namely, one with and one without a ventral fin mounted at

Prediction of transonic flutter for a supercritical wing by modified strip analysis and comparison with experiment [PDF]
Use of a supercritical airfoil can adversely affect wing flutter speeds in the transonic range. As adequate theories for three dimensional unsteady transonic flow are not yet available, the modified strip analysis was used to predict the transonic ...

Experimental transonic flutter characteristics of two 72 deg-sweep delta-wing models [PDF]
Transonic flutter boundaries are presented for two simple, 72 deg. sweep, low-aspect-ratio wing models. One model was an aspect-ratio 0.65 delta wing; the other model was an aspect-ratio 0.54 clipped-delta wing.
