Abstract

A runback system for receiving fluid from a deicing system may comprise a body and a first channel and a second channel defined by the body. A first end of the first channel may be spaced apart from a first end of the second channel. A second end of the first channel and a second end of the second channel may meet and form an outlet at an end of the body.

First claim

What is claimed is:

1. A pneumatic deicer, comprising:
a forming layer defining a volume configured to inflate and to deflate; and
a covering layer located over the forming layer, the covering layer defining a runback system including a plurality of channels, wherein a first channel of the plurality of channels is defined by a floor and a pair of walls extending from the floor to an outer surface of the covering layer, and wherein the floor of the first channel is sloped such that a distance between the floor of the first channel and an inner surface of the covering layer decreases in a forward to aft direction, the inner surface of the covering layer being opposite the outer surface of the covering layer.

2. The pneumatic deicer of claim 1 , wherein the covering layer comprises an elastomeric material.

3. The pneumatic deicer of claim 1 , wherein the first channel of the plurality of channels and a second channel of the plurality of channels are oriented in a V configuration.

4. The pneumatic deicer of claim 3 , wherein an aft end of the first channel and an aft end of the second channel meet and form an outlet at an aft end of the covering layer.

5. The pneumatic deicer of claim 1 , wherein the covering layer is tapered such that a height of the covering layer extending from the inner surface of the covering layer to the outer surface of the covering layer decreases in the forward to aft direction.

6. The pneumatic deicer of claim 1 , wherein a distance between the floor of the first channel and the outer surface of the covering layer increases in the forward to aft direction.

7. An aircraft part, comprising:
a deicing system; and
a runback system configured to receive fluid from the deicing system, the runback system comprising a first channel and a second channel, wherein the first channel is oriented at an angle relative to the second channel, and wherein a forward end of the first channel is spaced apart from a forward end of the second channel, and wherein an aft end of the first channel and an aft end of the second channel meet and form an outlet of the runback system.

8. The aircraft part of claim 7 , wherein the deicing system comprises a pneumatic deicer, the pneumatic deicer including:
a forming layer defining a volume configured to inflate and to deflate; and
a covering layer located over the forming layer.

9. The aircraft part of claim 8 , wherein the covering layer defines the runback system.

10. The aircraft part of claim 8 , wherein an aft end of the covering layer is located adjacent a forward end of the runback system.

11. The aircraft part of claim 7 , wherein a distal surface of the runback system is tapered such that a first height of the runback system at a forward end of the runback system is greater than a second height of the runback system at an aft end of the runback system.

12. The aircraft part of claim 7 , wherein a proximal surface of the runback system is affixed to a surface of the aircraft part.

13. The aircraft part of claim 7 , wherein the aircraft part comprises a wing of an aircraft.

14. The aircraft part of claim 7 , wherein the aircraft part comprises at least one of a horizontal stabilizer, a vertical stabilizer, or a nacelle inlet.

15. The aircraft part of claim 7 , wherein the deicing system comprises an electrothermal deicer.

16. A runback system configured to receive fluid from a deicing system, the runback system comprising:
a body;
a first channel defined by the body; and
a second channel defined by the body, wherein a first end of the first channel is spaced apart from a first end of the second channel, and wherein a second end of the first channel and a second end of the second channel meet and form an outlet at a first end of the body.

17. The runback system of claim 16 , wherein the first channel comprises:
a floor; and
a pair of walls extending from the floor to a first surface of the body.

18. The runback system of claim 17 , wherein a distance between the floor and a second surface of the body opposite the first surface of the body decreases in a direction extending from a second end of the body to the first end of the body, the second end of the body being located opposite the first end of the body.

19. The runback system of claim 17 , wherein the body is tapered such that a height of the body extending from the first surface of the body to a second surface of the body opposite the first surface decreases in a direction extending from a second end of the body to the first end of the body, the second end of the body being located opposite the first end of the body.
