Abstract

The method of Fast Floquet Theory is applied to the periodic-coefficient rotor flap equations in forward flight. The presence of dynamic inflow couples the individual blade equations. The results verify the claims of Fast Floquet Theory in that they verify the decrease in computer time and enhancement in modal determination that were predicted by earlier work. The results also reveal that the fundamental effects of periodicity can be greatly reduced by a transformation of the states to the appropriate coordinates. Thus, insight is gained into the effect of dynamic inflow on rotor response.
