Aerostatic-divergence of free-fixed slender elastic strip in uniform flow

1986 The Journal of the Japan Society of Aeronautical Engineering  
A static instability of a slender free-fiXed elastic sttrip in a uniform air stream is studied.The analysis is performed using slender body aerodynamic theory and beam theory. Both aerostatic divergence speed and divergence mode are fomd by the analysis. lt is seen by wind tunnel tests that there exist higher divergence speed based on linear lift and lower divergence speed due to nonlinear lift of slender body caused by side edge suction forces.
