Dankworth, Edwin G. (1951) An investigation of the effects of a sharp velocity gradient of the flexure-torsion flutter speed of an airfoil. Engineer's thesis, California Institute of Technology. http://resolver.caltech.edu/CaltechETD:etd-03132009-130943
This report covers the results of an experimental investigation of the effects of a velocity gradient on the flexure-torsion flutter speed of a NACA 0006 airfoil suspended by means of springs.
The presence of the velocity gradient produced no significant change in the speed at which the airfoil commenced normal self-excited oscillations. Oscillations of a torsional nature were found to occur at speeds considerably below the normal flutter speed. The causes of these torsional oscillations were not fully ascertained. It is reasoned however that they were due to flow conditions other than the presence of the velocity gradient.
