摘要： A gearbox includes an inlet configured to receive a mixture of air and oil from an external source and a deoiler. The deoiler includes a shaft including an inlet passage and an outlet passage, both formed on an inner portion of the shaft and separated from one another, a separator unit coupled to and surrounding a portion of the shaft and including an inlet and an outlet and a pre-pressuring component coupled to the shaft that increases the pressure of the mixture of oil and air to form a pressurized mixture and provides the pressurized mixture to the inlet of the separator unit.

摘要： A disclosed centrifugal boost pump volute includes normal to flow cross sectional surfaces distributed over the length of the passage. The volute includes a volute proper, an exit bend and a diffuser fluidly interconnecting the volute proper to the exit bend. The cross sectional surfaces are defined as dimensions set out in one set of data, which includes Tables N-1 and N-2 for the volute proper and Table N-3 for the volute exit bend, where N is the same value.
