  • Patent number: 11821363
    Abstract: An intake device for a gas turbine engine includes a snorkel and a particle separator. The snorkel is configured to be mounted to a panel defining at least a portion of a gas flow path within the gas turbine engine. The snorkel includes a tubular body extending between a closed end and an open end opposite the closed end. The snorkel further includes an inlet aperture formed through the tubular body adjacent the closed end. At least a portion of the snorkel is configured to be disposed within the gas flow path. The particle separator is mounted to the snorkel downstream of the inlet aperture. The particle separator includes at least one gas flow passage extending between a flow inlet and a flow outlet. The at least one gas flow passage is configured to remove particulate matter from the at least one gas flow passage upstream of the flow outlet.

  • Patent number: 11731778
    Abstract: A gas turbine engine includes an intake device. The intake device includes a snorkel and a filter case. The snorkel includes a tubular body and an inlet aperture. The tubular body extends between a closed end and an open end opposite the closed end. The inlet aperture is formed through the tubular body proximate the closed end. The tubular body forms a first portion of a gas flow path for a bleed gas from the inlet aperture to the open end. The filter case is connected to the tubular body. The filter case extends between a first end and a second end. The filter case includes a sidewall extending from the first end to the second end. The sidewall surrounds a filter cavity. The filter case is configured to receive the bleed gas from the open end of the tubular body. The filter case and the snorkel form a unitary component.

  • Patent number: 11585269
    Abstract: An intake device for a gas turbine engine includes a snorkel and a housing. The snorkel includes a tubular body and an inlet aperture. The tubular body extends between a closed end and an open end opposite the closed end. The inlet aperture is formed through the tubular body proximate the closed end. The housing is mounted to the snorkel. The housing includes an inner wall, an outer wall, a side wall, a settling chamber, and an outlet tube. The inner wall is adjacent the snorkel. The outer wall is opposite the inner wall. The side wall extends from the inner wall to the outer wall. The settling chamber is within the side wall between the inner wall and the outer wall. The settling chamber is fluidly coupled with the open end. The outlet tube extends through the housing from the settling chamber to an exterior of the housing.
