Energy conversion from liq. flowing horizontally in various turns - using folding or hinging cup-type vanes and based on principal of wind velocity gauge

摘要

Cup or tray-shaped vanes or scoops are mounted around a vertical cylinder. The closed backs of the scoop offer a streamline to any flow and therefore little resistance. The open ends offer full resistance to the flow. The vanes are either hinged half way along its length and at their fixing points or are made from a flexible mat erial so that they will be hinged out of the way to further reduce resistance when the flow approaches the blades from the rear. The rear faces of the blades are further provided with flaps which open when flow end-on. The function of these blades is to open out any blades which are hinged out of the way and to add further to the torque of the assembly.
