Appl. No.:

13/185457

International Classification:

F04D 29/58

US Classification:

417368, 4174238, 310 58, 415180

Abstract:

An example fan assembly impeller moves air along a secondary flow path when driven by a motor. The motor also drives a fan rotor to move air along a primary flow path of the fan assembly. Air moving along the primary flow path moves in a first direction. Air moving along the secondary flow path moves in a second direction opposite the first direction. An example fan shroud communicates air used to cool a motor into a primary flow path of a fan assembly. The shroud communicates the air into the primary flow path so that the flow of air is at least partially aligned with air moving through the primary flow path of the fan assembly.

International Classification:

F25B 9/00
B64D 13/06
F25B 9/06

Abstract:

An air cycle machine includes a housing having an exterior wall and an interior wall, a scavenging turbine supported for rotation within the housing, and an ambient air fan. The ambient air fan is supported for rotation within the housing and is operably associated with the scavenging turbine. The interior wall defines therethrough a turbine-fan port that fluidly couples the ambient air fan to the scavenging turbine for communication of an overboard air flow to an ambient air flow without external ducting. Environmental control systems and methods of flowing fluid through air cycle machines are also described.

- Charlotte NC, US
Roberto J. Perez - Windsor CT, US

International Classification:

F28F 9/22
F28D 9/00

Abstract:

A heat exchanger includes a stack of flow conduits. Each flow conduit is configured to conduct a fluid. Parting sheets separate adjacent flow conduits in the stack, providing heat transfer between them. Each of the flow conduits includes vanes extending along a vane path and between top and bottom parting sheets. The vanes are separated from one another, thereby creating flow channels. Each flow conduit also includes a plurality of flow modifiers, each adjacent to a corresponding leading edge of a corresponding vane, so as to cause a disrupted portion of a fluid flow to be incident upon the corresponding leading edge. Each of the flow modifiers includes an aerodynamic portion and a gap portion. The aerodynamic portion extends from at least one of the top and bottom parting sheets. The aerodynamic portion does not connect the top and bottom parting sheets due to the gap portion.

Abstract:

An embodiment of an electric motor assembly includes a stator assembly extending generally along the longitudinal axis and at least partially enclosing a rotor assembly also extending along the longitudinal axis. The rotor assembly includes a rotating portion and one or more sets of rotor windings. The stator assembly includes a stationary housing having at least an inner wall and an outer wall, and one or more sets of stator windings in electromagnetic communication with the one or more sets of rotor windings. A heat exchanger is integrally formed into the housing, and includes a plurality of dividing walls extending between the inner and outer housing walls. The plurality of dividing walls are arranged at least partially circumferentially around the longitudinal axis to define, with the inner and outer walls, a corresponding plurality of integral heat exchanger channels arranged at least partially circumferentially around the one or more sets of stator windings. A plurality of rib turbulators are disposed on at least a channel-facing surface of the inner wall.

International Classification:

F04D 29/32
F04D 25/06
F04D 29/38
B64D 13/08

Abstract:

A fan rotor for a ram air fan includes a hub and blades extending radially outwards from the hub. The hub includes an inner hub portion, a disk portion connected to a radially outer surface of the inner hub portion, and an outer hub portion connected to a radially outer surface of the disk portion. The outer hub portion has an upstream arm with a compound contoured surface. The compound contoured surface is configured to direct air flow around the compound contoured surface and along roots of the blades.

International Classification:

F28C 3/02
F28D 9/00
F28F 13/06
F28F 27/02

Abstract:

A heat exchanger assembly includes a plurality of first and second fluid passages defined by a pair of opposing first fluid passage walls and a plurality of first fluid diverters disposed between the first fluid passages walls. The second fluid passages are defined by a pair of opposing second fluid passage walls and a plurality of second fluid diverters disposed between the second fluid passage walls. An ejector is integrated into the heat exchanger assembly. The ejector includes: an integral ejector passage, wherein the integral ejector passage is a first fluid passage; a primary inlet configured to receive a hot fluid; an outlet nozzle configured to eject the hot fluid; a secondary inlet configured to receive a cold fluid, wherein the secondary inlet is in fluid communication with a second fluid passage; and a mixing section in fluid communication with the outlet nozzle and the secondary inlet.
