Aeroelastically tailored propellers for noise reduction and improved efficiency in a turbomachine are provided including one or more upstream blades and one or more downstream blades disposed downstream relative to the one or more upstream blades. Each of the one or more upstream blades and the one or more downstream blades are aeroelastically tailored such that the one or more downstream blades include a greater degree of effective clipping during a second condition than at a first condition. Each blade among the one or more upstream blades comprises one or more geometric parameters. Each blade among the one or more downstream blades comprises one or more geometric parameters. In addition, an open rotor aircraft gas turbine engine assembly including the aeroelastically tailored propellers and a method of decreasing noise and improving efficiency in a turbomachine are disclosed.
