Abstract: A monolithic heater body includes a combustor body and an eductor body. The combustor body has an annulus with an outward annular wall and an inward annular wall. The annulus defines a conditioning conduit between the outward annular wall and the inward annular wall, and a combustion chamber circumferentially surrounded by the inward annular wall. A distal portion of the conditioning conduit fluidly communicates with a distal portion of the combustion chamber. The eductor body defines a plurality of eductive pathway couplets circumferentially spaced about a perimeter of the annulus. Respective ones of the eductive pathway couplets have a motive pathway and an eduction pathway respectively oriented oblique to the annulus and fluidly communicating with the conditioning conduit. Respective ones of the plurality of motive pathways are configured to provide a jet of intake air from a corresponding plurality of intake air pathways to the conditioning conduit.

Abstract: An electric machine includes a stator and a rotor operable with the stator. The rotor includes at least one pole section, the pole section defining a direct axis in a flux barrier having a first end and a second end. Each of the first and second ends are positioned proximate to the stator. The first end defines a first angular position relative to the direct axis and the second end defines a second angular position relative to the direct axis. The first angular position is different in magnitude than the second angular position to reduce a torque ripple or torque oscillation of the electric machine.

Abstract: A method of detecting a vibration node between a non-collocated sensor-actuator pair of a rotatable component includes applying an excitation signal to an actuator of the sensor actuator pair. The method also includes obtaining frequency response data from the sensor-actuator pair. The method further includes analyzing the frequency response data to ascertain a resonant frequency of the rotatable component. The method includes identifying a resonance/anti-resonance peak pair in the frequency response data for the non-collocated sensor-actuator pair. Furthermore, the method includes determining whether the vibration node is located between a sensor and the actuator of the non-collocated sensor-actuator pair based on the resonance/anti-resonance peak pair.
