A propeller (32) is provided including a hub (36) and a first blade group (50a) and a second blade group (50b). The first blade group (50a) includes at least one first propeller blade (40a) and the second blade group (50b) includes at least one second propeller blade (40b). The at least one first propeller blade (40a) and the at least one second propeller blade (40b) are mounted to and equidistantly spaced about the hub (36). The at least one first propeller blade (40a) of the first blade group (50a) has at least one geometric characteristic different from the at least one second propeller blade (40b) of the second blade group (50b). The different blade groups (50a-50d) will generate different noise signatures over a wider range of frequencies allowing for the design of low noise propeller systems.
