    摘要: A liquid scavenging pump system for scavenging oil or the like from a blower, an engine or the like. A casing is provided for housing the blower and defining an oil receiving cavity. A dual pump is mounted in the casing and has first and second pumps in communication with the casing cavity for conjoint rotation. A first inlet is provided from the casing cavity to the first pump, and a first outlet is provided from the first pump for delivering oil from the cavity to a pump or the like. A second inlet is provided from the casing cavity, remote from the first inlet, to the second pump. The second outlet from the second pump is in communication with the first inlet to the first pump to facilitate operating the pump at various attitudes. The dual pump is of the radial-vaned impeller type, but includes two sets of axially spaced impeller vanes separated by a common barrier and including a sleeve for mounting on a common drive shaft. The impeller vanes, the barrier and the sleeve all are fabricated as a single unitarily constructed structure, such as by molding.

    摘要: An emergency power system for use on an aircraft includes an emergency electrical generator coupled to a mechanical power source for generating emergency electrical power. An electrical power distribution network connects the emergency electrical generator to a plurality of electrical loads. A controller controls the electrical power distribution network to selectively couple and decouple the electrical loads to and from the emergency electrical generator based upon a priority rank assigned to each of the electrical loads.
