Abstract
A particle separation device to remove particulate matter from an exterior air flow for use with an environmental control system includes a curved airflow path with an inner radius and an outer radius, the curved air flow path to receive the exterior air flow, a particle passage disposed along at least one of the inner radius and the outer radius to receive the particulate matter from the exterior air flow, a circumferential volute to receive the particulate matter from the particle passage, and a duct to transport the particulate matter from the circumferential volute to a downstream region.
Claims15
A particle separation device to remove particulate matter from an exterior air flow for use with an environmental control system, the particle separation device comprising:
- a curved airflow path with an inner radius and an outer radius, the curved air flow path to receive the exterior air flow;
- a particle passage disposed along at least one of the inner radius and the outer radius to receive the particulate matter from the exterior air flow;
- a circumferential volute to receive the particulate matter from the particle passage;
- and
- a duct to transport the particulate matter from the circumferential volute to a downstream region,
- wherein:
- the exterior air flow moves in a first predominant direction, and
- the curved airflow path redirects a portion of the exterior air flow, which is not received in the particle passage, such that the portion of the exterior air flow exits the curved airflow path in a second predominant direction opposite the first predominant direction for reception in the downstream region wherein:
- the duct comprises a first axial component extending from the circumferential volute, a radial component extending from an end of the first axial component and a second axial component extending from an end of the radial component to a first portion of the downstream region, the curved airflow path redirects the exterior air flow approximately 180 degrees into a second portion of the downstream region, and a heat exchanger is interposed between the first and second portions of the downstream region.
A particle separation system to remove particulate matter from an exterior air flow for use with an environmental control system, the particle separation system comprising:
- a fan to accelerate the exterior air flow;
- a curved airflow path with an inner radius and an outer radius, the curved air flow path to receive the exterior air flow;
- a heat exchanger to receive the exterior air flow from the curved air flow path;
- a particle passage disposed along at least one of the inner radius and the outer radius to receive the particulate matter from the exterior air flow;
- a circumferential volute to receive the particulate matter from the particle passage;
- and
- a duct to transport the particulate matter from the circumferential volute to a downstream region disposed downstream of the heat exchanger,
- wherein:
- the exterior air flow moves in a first predominant direction, and
- the curved airflow path redirects a portion of the exterior air flow, which is not received in the particle passage, such that the portion of the exterior air flow exits the curved airflow path in a second predominant direction opposite the first predominant direction for reception in the downstream region wherein:
- the duct comprises a first axial component extending from the circumferential volute, a radial component extending from an end of the first axial component and a second axial component extending from an end of the radial component to a first portion of the downstream region, the curved airflow path redirects the exterior air flow approximately 180 degrees into a second portion of the downstream region, and a heat exchanger is interposed between the first and second portions of the downstream region.
