Upstream-Propagating Potential Disturbances Interacting with A Compressible Cascade

A Study of Impulse Forcing on a Simply Supported Blade

“…The large-cylinder data also exhibit probability distributions corresponding to a approximately random (bell shaped) strain, even though cylinder wakes are known to produce periodic forcing. 10,11 A probability distribution for a theoretical purely sinusoidal strain with 500 µε amplitude is included in Figure 5 In interpreting the results of Figure 5.3 and Figure 5.4, it should be noted that Sears 13 theoretically predicted aerodynamic loading of a thin flat-plate airfoil due to sinusoidal forcing (or gusts). He showed airfoil loading to increase with forcing function amplitude and decrease with reduced frequency, as defined by…”
