Experimental and analytical transonic flutter characteristics of a geared-elevator configuration [PDF]

open access: yes
The flutter model represented the aft fuselage and empennage of a proposed supersonic transport airplane and had an all movable horizontal tail with a geared elevator. It was tested mounted from a sting in the transonic dynamics tunnel. Symmetric flutter

Preliminary study of effects of winglets on wing flutter [PDF]

open access: yes
Some experimental flutter results are presented over a Mach number range from about 0.70 to 0.95 for a simple, swept, tapered, flat-plate wing model having a planform representative of subsonic transport airplanes and for the same wing model equipped ...

Optical measurement of unducted fan flutter [PDF]

open access: yes
A nonintrusive optical method is described for flutter vibrations in unducted fan or propeller rotors and provides detailed spectral results for two flutter modes of a scaled unducted fan. The measurements were obtained in a high-speed wind tunnel.

Further studies of stall flutter and nonlinear divergence of two-dimensional wings [PDF]

open access: yes
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.

Experimental parametric studies of transonic T-tail flutter [PDF]

open access: yes
Wind-tunnel tests of the T-tail of a wide-body jet airplane were made at Mach numbers up to 1.02. The model consisted of a 1/13-size scaled version of the T-tail, fuselage, and inboard wing of the airplane.
