Abstract

A wire support member for an environmental control system includes a bracket having an inner surface, an outer surface, and a thickness. A first arm projects from the bracket, a first flange projects from a first end of the first arm. The first flange includes a first harness support opening therethrough. A second arm also projects from the bracket parallel to the first arm, and a second flange projects from a second end of the second arm. The second flange has a second harness support opening therethrough. A ratio of a diameter of the first harness support opening and of the second harness support opening to the thickness of the bracket optimizes the routing and support for the wiring.

Claims

1. A wire support assembly for an environmental control system, the wire support assembly comprising:

a wiring for the environmental control system comprising;

a first wire bundle extending from a pack control unit and branching into a second wire bundle and a third wire bundle;

the second wire bundle extending from the first wire bundle to an outboard module; and

the third wire bundle extending from the first wire bundle to an inboard module;

a first wire support member mounted to a first backbone support structure, the first wire support member supporting the first wire bundle, the second wire bundle, and the third wire bundle, the first wire support member comprising;

a bracket having an inner surface, an outer surface, and a thickness T1;

a first arm projecting from the bracket;

a first flange projecting from a first free end of the first arm, the first flange having a first harness support opening therethrough, the first harness support opening having a diameter D1;

a second arm projecting from the bracket and oriented in a plane with the first arm; and

a second flange projecting from a second end of the second arm, the second flange having a second harness support opening therethrough, the second harness support opening having a diameter D2;

a second wire support member mounted to an outboard support structure of the outboard module, the second wire support member supporting the second wire bundle between the first wire support member and the outboard module; and

a third wire support member mounted to a first compressor casing of the inboard module, the third wire support member supporting the third wire bundle between the first wire support member and the inboard module.

2. The wire support structure of claim 1, wherein a ratio of D1 to T1 is between 10.5 and 9.0.

3. The wire support structure of claim 1, wherein a ratio of D2 to T1 is between 10.5 and 9.0.

4. The wire support structure of claim 1, wherein T1 is between 0.119 inches (0.302 centimeters) and 0.131 inches (0.333 centimeters).

5. The wire support structure of claim 1, wherein a length of the first arm is greater than a length of the second arm.

6. The wire support structure of claim 1, wherein D1 is between 1.209 inches (3.070 centimeters) and 1.229 inches (3.122 centimeters) and D2 is between 1.209 inches (3.070 centimeters) and 1.229 inches (3.122 centimeters).

7. The wire support structure of claim 1, further comprising:

a clamp mounted to the inner surface of the bracket, the first wire harness supported by the clamp.

8. The wire support structure of claim 7, wherein the clamp includes an elastomer cushion secured between the clamp and the second wire bundle.
