Abstract: A rotor assembly is provided. The rotor assembly includes a plurality of blades spaced circumferentially. An airfoil of each blade includes a pressure side, a suction side, a pressure side nub extending from the pressure side, and a suction side nub extending from the suction side. An airfoil length is greater than one of (i) 40 inches, wherein the rotor is configured for operation at about 3600 rpm, and (ii) 48 inches, wherein the rotor is configured for operation at about 3000 rpm. The rotor assembly also includes a plurality of sleeves. Each of the sleeves extends from a first end to a second end. The first end is coupled to the pressure side nub of a first of the blades and the second end is coupled to the suction side nub of an adjacent second of the blades.

Abstract: Heating systems for a rotor in-situ in a turbomachine are provided. In contrast to conventional systems that merely heat from an external turbine casing, embodiments of the disclosure heat the rotor. In one embodiment, a heating system includes a heating element to heat a portion of an exterior surface of the rotor. In another embodiment, the heating system may include a heating element(s) at least partially positioned within the rotor, and the rotor including the heating system. Each embodiment may include a controller to control operation of the heating element(s).

Abstract: A battery pack is described. The battery pack includes a plurality of electrochemical cells, wherein the electrochemical cells are isolated from each other by a concrete. The concrete includes a composite cement having from about 20 percent to about 80 percent aggregate of high packing density, by weight of the composite cement. Methods for providing electrical isolation between individual electrochemical cells are also described.
