Abstract

A water extractor includes a body with an outer wall, an inlet, an outlet, a first centerline axis, an inner nozzle, an outer chamber, a serpentine channel, a pocket, and a boss. The first centerline axis extends through a center of the body, the outlet, and the inlet. The inner nozzle is co-axial with the first centerline axis. The outer chamber extends between the outer wall and the inner nozzle. The serpentine channel fluidly connects the inlet and the outer chamber. The pocket is fluidly connected to a portion of the outer chamber and is configured to collect water from the outer chamber. The boss extends from and is fluidly connected to the pocket. The boss includes a second centerline axis at an angle with the first centerline axis of approximately 10 degrees or greater.

First claim

The invention claimed is:

1. A water extractor comprising:
a body with an outer wall;
an inlet disposed on an upstream end of the body;
an outlet disposed on a downstream end of the body;
a first centerline axis extending through a center of each of the body, the outlet, and the inlet, wherein an angle between the first centerline axis and a horizontal plane is approximately 10 degrees or greater, wherein the horizontal plane is representative of a horizontal direction when the aircraft is on the ground or is in horizontal flight;
an inner nozzle disposed radially inward from the outer wall, wherein the inner nozzle is co-axial with the first centerline axis;
an outer chamber disposed in the body and extending between the outer wall and the inner nozzle, wherein the outer chamber is fluidly connected to the inlet and the outlet;
a serpentine channel disposed radially between the outer wall of the body and the inner nozzle;
an annular gap disposed radially outward from the inner nozzle, wherein the annular gap fluidly connects the inlet and the serpentine channel;
a pocket attached to a portion of the outer wall of the body and fluidly connected to a portion of the outer chamber, wherein the pocket is configured to collect water from a flow of fluid passing through the outer chamber; and
a boss extending from and fluidly connected to a portion of the pocket, wherein the boss includes a second centerline axis, wherein an angle between the second centerline axis and the first centerline axis is approximately 10 degrees or greater.

2. The water extractor of claim 1 , wherein the pocket is disposed on a gravitational bottom portion of the body.

3. The water extractor of claim 1 , wherein the water extractor is configured as an inertial particle separator.

4. The water extractor of claim 1 , wherein the second centerline axis of the boss is approximately parallel to a horizontal plane.

5. The water extractor of claim 1 , wherein the serpentine channel is disposed radially outwards from and circumferentially surrounds the inner nozzle, and further wherein the serpentine channel is configured to guide a direction of flow passing through the serpentine channel from a downstream direction, to an upstream direction, and back to the downstream direction.

6. The water extractor of claim 1 , wherein the outer wall of the body comprises a downstream portion and an upstream portion located upstream from the downstream portion relative to a direction of flow through the inner nozzle, wherein the pocket comprises an upstream end and a downstream end, wherein the upstream end of the pocket is attached to the upstream portion of the outer wall, and wherein the boss is connected to the downstream end of the pocket.

7. A method of extracting water from a flow of air, the method comprising:
swirling the flow of air;
inserting the flow of air into a water extractor, wherein the water extractor includes a first centerline axis passing through a center of the water extractor along a longitudinal direction of the water extractor, wherein an angle between the first centerline axis and a horizontal plane is approximately 10 degrees or greater, wherein the horizontal plane is perpendicular to a direction of gravity;
splitting the flow of air into a primary flow and a secondary flow within the water extractor;
diverting the secondary flow into an outer chamber of the water extractor, wherein the outer chamber is disposed between an inner nozzle and an outer wall of a body of the water extractor;
receiving water separated from the secondary flow into a pocket fluidly connected to the outer chamber and attached to the outer wall of the body of the water extractor;
communicating the water received by the pocket into a boss connected to the pocket; and
drawing the water from the boss, wherein the boss includes a second centerline axis that is set at a first angle relative to the first centerline axis, wherein the first angle is approximately 10 degrees or greater.

8. The method of claim 7 , further comprising:
sending the flow of air from a condenser of an air conditioning pack to the water extractor;
rejoining the primary flow and secondary flow in an outlet of the water extractor after removing water from the secondary flow to form a resultant flow of air; and
sending the resultant flow of air to an air cycle machine that is fluidly connected to the water extractor.

9. The method of claim 7 , wherein receiving water from the secondary flow into the pocket further comprises withdrawing water from the secondary flow from an upstream end of the outer chamber.

10. The method of claim 7 , wherein receiving water from the secondary flow into the pocket further comprises withdrawing water from the secondary flow at a gravitational bottom of the body.

11. The method of claim 7 , wherein a second angle between the first centerline axis and a horizontal plane is greater than zero degrees.

12. An air conditioning pack for an aircraft, the air conditioning pack comprising:
a condenser;
an air cycle machine fluidly connected to the condenser; and
a water extractor fluidly connecting the condenser to the air cycle machine, the water extractor comprising:
a body with an outer wall, wherein the outer wall comprises an upstream portion and a downstream portion;
an inner nozzle disposed radially inward from the outer wall, wherein the upstream and downstream portions of the outer wall are oriented relative to a direction of a flow of fluid through the inner nozzle;
an inlet disposed on an upstream end of the body and fluidly connected to the condenser;
an outlet disposed on a downstream end of the body and fluidly connected to the air cycle machine;
a first centerline axis extending through a center of each of the body, the outlet, and the inlet, wherein an angle between the first centerline axis and a horizontal plane is approximately 10 degrees or greater, wherein the horizontal plane is representative of a horizontal direction when the aircraft is on the ground or is in horizontal flight;
an outer chamber disposed in the body and extending between the outer wall and the inner nozzle, wherein the outer chamber is fluidly connected to the inlet and the outlet, wherein the outer chamber comprises an upstream portion and a downstream portion, wherein the outer chamber is configured to receive a flow moisture-laden air from the inlet, and wherein the outer chamber is configured to deposit moisture from the flow moisture-laden air onto the outer wall;
a pocket connected to the outer wall of the body, wherein the pocket comprises an upstream portion and a downstream portion, wherein the upstream portion of the pocket is attached to the upstream portion of the outer wall and is fluidly connected to the upstream portion of the outer chamber, and wherein the pocket is configured to collect the deposited moisture from the outer wall; and
a boss extending from the pocket, wherein the boss is fluidly connected to the upstream portion of the outer chamber via the pocket, wherein the boss is configured to withdraw the collected moisture from the pocket.

13. The air conditioning pack of claim 12 , wherein a portion of the pocket is connected to a location of the outer wall of the body that is at a gravitational bottom of the outer wall of the body.

14. The air conditioning pack of claim 13 , wherein the water extractor is configured as an inertial particle separator.

15. The air conditioning pack of claim 13 , further comprising:
a serpentine channel disposed radially between the inner nozzle and the outer chamber; and
an annular gap disposed
