CALCULATING THE CRITICAL FLUTTER SPEED OF THE FAN BLADE

Calculating the critical flutter speed of the fan blade

The tendency to create modern gas turbine engines requires shortening the development time, which includes: design, manufacturing, and finalization.Developers strive to reduce the cost of finalization, which involves changes in design and associated refinement costs.Special attention is given to the major engine design elements, such as the fan, co

Transient dynamic left ventricular outflow tract obstruction

Dynamic left ventricular outflow (LVOT) obstruction has been classically described in patients with hypertrophic cardiomyopathy (HCM).The hypertrophy of the basal septum and systolic anterior motion of the mitral valve leaflet (SAM) cause dynamic LVOT obstruction.In addition, HCM also shows speckled appearance of myocardium and LVOT obstruction is
