Dm. Tang et Eh. Dowell, EXPERIMENTAL INVESTIGATION OF 3-DIMENSIONAL DYNAMIC STALL MODEL OSCILLATING IN PITCH, Journal of aircraft, 32(5), 1995, pp. 1062-1071
The ONERA semiempirical theoretical model for unsteady aerodynamics in
the stall regime has been extended to three-dimensional flow. Paramet
er identification for the model is obtained from experimental dynamic
stall data for a low AR rectangular wing with a NACA 0012 airfoil prof
ile oscillating in pitch. Excellent correlations were obtained with th
e measured data for a three-dimensional linear aerodynamic model and r
easonable agreement between theory and test data were obtained for a n
onlinear (stalled) aerodynamic model. Qualitatively, the results obtai
ned for this simple three-dimensional wing are similar to the correspo
nding data for the two-dimensional airfoil.
