Abstract: An electric machine includes a stator having a stator bore and a stator winding. The stator winding is arranged to one of receive an electrical current and produce an electrical current having a power between 1 MW and 50 MW. The stator has a stator current density of greater than 5 A/mm2. A rotor is at least partially disposed within the stator bore and has a rotor winding. The rotor has a rotor current density of greater than 5 A/mm2. A high-pressure cooling system is operable to actively cool the stator and the rotor. The rotor winding and the stator winding interact to one of produce rotation of the rotor to drive a connected device in response to the receipt of the electrical current and produce the electrical current in response to rotation of the rotor driven by the connected device.

Abstract: A method of additively manufacturing is provided. The method may include successively depositing and fusing together layers of a superalloy powder mixture comprised of a base material powder and a eutectic powder, to build up an additive portion, which eutectic powder has a solidus temperature lower than the solidus temperature of the base material powder. The method may also include heat treating the additive portion at a temperature greater than 1200° C. to heal cracks and/or fill pores and to homogenize the alloy of which the additive portion is comprised. The additive portion alloy has a chemistry defined by the superalloy powder mixture.

Abstract: A computer-implemented method of detecting an anomalous action associated with a physical system includes developing, by a computing device a plurality of vectors, each vector indicative of an event that occurred at a specific time within the system, combining, with the computing device each vector that occurred within a predefined time duration into one of a plurality of master vectors, and performing, with the computing device a cluster analysis to group each master vector of the plurality of master vectors into one of a plurality of states. The method also includes determining, with the computing device a real-time master vector based at least in part on one or more events that occur within the predefined time duration, classifying, with the computing device the real-time master vector as a real-time state, and indicating that the real-time state is anomalous when the real-time state doesn't match one of the plurality of states.
