Further studies of stall flutter and nonlinear divergence of two-dimensional wings [PDF]
An experimental investigation is made of the purely torsional stall flutter of a two-dimensional wing pivoted about the midchord, and also of the bending-torsion stall flutter of a two-dimensional wing pivoted about the quarterchord.
