Abstract
Various connection units are disclosed. The connection unit can be configured to straighten a flow of air, such as to reduce the distance before the flow of air becomes substantially laminar. The connection unit can include a drag reduction unit. The drag reduction unit can be configured to redirect airflow to the center of the connection unit. The connection unit can include a wake diverting component configured to lift air away from the periphery of the connection unit and/or redirect the airflow towards a radial center connection unit.
Claims20
A system for redirecting airflow, the system comprising:
- an upstream component comprising an engagement portion on a downstream end of the upstream component;
- a connection unit comprising:
- an upstream engagement portion;
- a drag reduction unit positioned at or near an upstream end of the connection unit;
- a wake diverting component protruding from an internal surface of the connection unit, the wake diverting component located downstream of the drag reduction unit;
- and
- a downstream engagement portion;
- a downstream component comprising an engagement portion on an upstream end of the downstream component;
- wherein the upstream engagement portion of the connection unit is configured to engage with the engagement portion of the upstream component, and wherein the downstream engagement portion of the connection unit is configured to engage with the engagement portion of the downstream component;
- and
- wherein the connection unit is configured to receive a flow of non-laminar air from the upstream component and to provide, within a distance of less than or equal to 12 inches downstream of the connection unit, a flow of substantially laminar air to the downstream component,
- wherein the connection unit is formed from a first connector portion and a second connector portion that are separable from each other.

A system for redirecting airflow, the system comprising:
- an upstream component comprising an engagement portion on a downstream end of the upstream component;
- a connection unit comprising:
- an upstream engagement portion;
- an outer duct comprising an outer wall and a passage, the outer duct configured to convey a flow of air through the passage;
- a support coupled with the outer wall;
- a drag reduction unit coupled with the support and positioned in the passage;
- a wake diverting component protruding from an internal surface of the connection unit, the wake diverting component located downstream of the drag reduction unit;
- a downstream engagement portion;
- wherein the support includes a plurality of support structures each coupled to the outer wall and to the drag reduction unit and configured as vanes for straightening the flow of air through the passage;
- and
- a downstream component comprising an engagement portion on an upstream end of the downstream component;
- wherein the upstream engagement portion of the connection unit is configured to engage with the engagement portion of the upstream component, and wherein the downstream engagement portion of the connection unit is configured to engage with the engagement portion of the downstream component,
- wherein the downstream engagement portion further comprises a first mating feature extending substantially around a periphery of the passage at the downstream end of the connection unit, wherein the first mating feature is configured to engage and secure the downstream component to the connection unit, and wherein the upstream engagement portion of the connection unit comprises a second mating feature extending substantially around a periphery of the passage at the upstream end of the connection unit, wherein the second mating feature is configured to engage and secure the upstream component to the connection unit.
