摘要： A turbomachinery engine includes a fan assembly, a low-pressure turbine, and a gearbox. The fan assembly includes a plurality of fan blades. The low-pressure turbine includes 3-5 rotating stages. The low-pressure turbine includes an area ratio equal to the annular exit area of an aft-most rotating stage of the low-pressure turbine divided by the annular exit area of a forward-most rotating stage of the low-pressure turbine. In some instances, the area ratio is within a range of 2.0-6.5. Additionally (or alternatively) the low-pressure turbine includes an area-EGT ratio within a range of 1.3-1.6.

摘要： Unitary ceramic components, along with methods of their formation, are provided. The unitary ceramic component (100) may include a first densified ceramic component (110); a second densified ceramic component (120); and a series-hybrid joint (200) (200) coupling the first densified ceramic component (110) to the second densified ceramic component (120), where the series-hybrid joint (200) (200) comprises a first bonding area (210) coupling the first densified ceramic component (110) and the second densified ceramic component (120), and a second bonding area (220) coupling the first densified ceramic component (110) and the second densified ceramic component (120), where the first bonding area (210) exhibits properties that are different from the second bonding area (220). The first bonding interface (210) has a strength that is greater than the second bonding interface (220), whereas the second bonding interface (220) has a hermeticity that is greater than the first bonding interface (210), or a chemical resistance that is greater than the first bonding interface (210).

摘要： Example systems, methods, and apparatus are disclosed herein. Disclosed systems include a superconducting (SC) motor to power a propulsor of an aircraft and a liquid hydrogen (LH2) subcooling system including a primary flowline fluidly coupled to a cooling assembly of the SC motor, a secondary flowline fluidly coupled to the primary flowline, an expansion valve coupled to the secondary flowline, and a heat exchanger fluidly coupled to the primary flowline and the secondary flowline. Disclosed systems also include a fuel cell stack coupled to the primary flowline and the cooling assembly.

摘要： A multilevel power converter (200) includes a plurality of switches (242), a first DC link capacitor (C1), a second DC link capacitor (C2), and one or more processors (610A) configured to: generate, for a duty cycle of the multilevel power converter (200), a pulse width modulated pulse pattern (226) in accordance with a reduced common mode voltage scheme; modify the pulse width modulated pulse pattern (226) to render a modified pulse pattern (236); and cause the plurality of switches (242) to implement the duty cycle based at least in part on the modified pulse pattern (236) to render a common mode voltage pulse (CMVP1) to balance voltages at the first DC link capacitor (C1) and the second DC link capacitor (C2).

摘要： A reclamation system (46) for an additive manufacturing apparatus (10) can include a collection structure (130) configured to remove at least a portion of the resin (R) from a foil (28). A containment vessel (138) can be configured to retain the resin (R) removed from the foil (28). A drain can direct the resin (R) from the containment vessel (138) to a reservoir (158).
