摘要: Removing unfused powder from internal passages of an additive-manufacture part includes attaching piezoelectric transducers to a plurality of locations on an exterior of the part. The part is vibrated by driving the piezoelectric transducers at varying amplitudes and frequencies. An amount of the unfused powder that exits the part is monitored.

摘要: A plate fin heat exchanger is configured to receive hot flow from a hot source and cool flow from a cool source. The plate fin heat exchanger includes a plurality of plates arranged in parallel to define a plurality of flow passages there between, and a set of closure bars arranged at a first side of the plurality of plates to seal a first set of the flow passages against ingress of the hot flow, thereby directing the hot flow into a second set of the flow passages. Each respective closure bar includes an inner core formed of a first material having a first coefficient of thermal expansion and an outer cladding arranged about the inner core, the outer cladding formed of a second material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is less than the second coefficient of thermal expansion.

摘要: A counter-flow heat exchanger including: a primary flow passageway comprising a primary flow inlet, a primary flow outlet, and a plurality of primary flow subset passageways therebetween; a secondary flow passageway comprising a secondary flow inlet, a secondary flow outlet, and a plurality of secondary flow subset passageways therebetween; and a heat exchanger core comprising portions of the plurality of primary flow subset passageways and the plurality of secondary flow subset passageways, the secondary flow passageway being in thermal communication with the primary flow passageway in the heat exchanger core, wherein the primary flow subset passageways in the heat exchanger core and the secondary flow subset passageways in the heat exchanger core are oriented such that primary fluid flow through the primary flow subset passageways flows opposite secondary fluid flow through the secondary flow subset passageways.

摘要: A self-acting pressure activated drain valve includes at least one inlet configured to receive a fluid. A drainage passage delivers the fluid to at least one outlet where the fluid is expelled. The self-acting pressure activated drain valve further includes a flexible diaphragm configured to operate in an open position and a closed position based on a pressure. The flexible diaphragm is normally biased in the open position such that fluid is delivered from the at least one inlet to the at least one outlet via the drainage passage. The pressure, however, initiates the closed position such that air is prevented from flowing through the drainage passage.

摘要: A water extractor for an environmental control system includes a primary duct having an inlet and an outlet, a scupper with a scupper inlet extending about the inlet of the primary duct, and a supply duct. The supply duct is in fluid communication with the primary duct and has a wall with an interior surface terminating at the scupper inlet. The interior surface defines one or more one swirl groove within the wall for gathering and conveying liquid water entrained in an airflow traversing the inlet duct to the scupper inlet. Environmental control systems, methods of making water extractors, and methods of removing water from air flows are also described.

摘要: A plate fin heat exchanger includes a plate fin core having a plurality of plates defining a set of hot air passages extending from a hot air inlet region of the plate fin core to a hot air outlet region of the plate fin core and a set of cool air passages extending from a cool air inlet region of the plate fin core to a cool air outlet region of the plate fin core. The plate fin heat exchanger further includes a mounting flange circumscribing the cool air outlet region. At least a portion of the mounting flange has a plurality of heat transfer structures that extend into a flow path of cooling air exiting the cool air outlet region of the plate fin core.
