Fluttering conditions of webs were analyzed for a flexible sheet with both leading and trailing edges fixed in a uniform flow by the method proposed in (1). The predicted flutter limits are expressed in terms of a ratio of fluid force to tension (σ^*) and a ratio of tension to bending stiffness (τ^*). For τ^* greater than 1000,σ^* and reduced frequency are of nearly constant values, respectively. For τ^* less than 1000,effect of bending stiffness appears and divergence-like instabilities having lower frequencies occur before the flutter.
