Open the CIPO recordAbstract From the Canadian patent
In an impeller element of a radial inflow gas turbine the shape of the blades and the outer profile of the hub are such as to make the impeller symmetric about two planes, one through the axis of rotation and one normal to it, the impeller thus deviating from the conventional shape of radial inflow gas turbine impellers which to a considerable degree, has been adapted to the theoretical path of the gas.
