ABSTRACT:
A fluid current motor having a rotatable shaft, a plurality of rotor arms rigidly mounted to and extending radially outwardly from the shaft and a plurality of pairs of superposed rotor panels which pairs are pivotally mounted respectively to each said rotor arm, may be improved by providing a rigid connector between each pair of panels moveably connecting a leading portion of one rotor panel in each said pair to a trailing portion of the second rotor panel in each said pair such that the rotor panels in each pair of rotor panels will coactingly pivot between resisting and non-resisting positions in response to a fluid current.
