Abstract

A transition duct assembly includes a shared connector, and a plurality of primary cooling pathways for cooling one or more systems or components. Each primary cooling pathway includes a transition duct in fluid communication with the shared connector, and a transition connector in fluid communication with the transition duct.

Claims (19)

1. A transition duct assembly, comprising:

a main rotor gearbox;

a cooling apparatus connected to and downstream from the main rotor gearbox;

a shared connector connected to the cooling apparatus, wherein the shared connector comprises an articulatable partition; and

at least two primary cooling pathways connected to the shared connector for cooling one or more systems or components, wherein each primary cooling pathway comprises:

a transition duct in fluid communication with the shared connector; and

a transition connector in fluid communication with the transition duct, wherein articulation of the articulatable partition from a first to a second position allows for air flow over most or all of the cooling apparatus.

2. The assembly of claim 1 , wherein the articulatable partition separates flow into at least two channels wherein each transition duct is in fluid communication with the at least two channels within the shared connector.

3. The assembly of claim 2 , wherein the articulatable partition is articulated or actuated.

4. The assembly of claim 1 , wherein each transition duct comprises at least a portion that is a rigid material, a flexible material, an articulated portion, a flexible portion, or a combination thereof.

5. The assembly of claim 1 , further comprising one or more secondary cooling pathways, wherein each of the one or more secondary cooling pathways comprises a conduit in fluid communication with the transition duct of one of the at least two primary cooling pathways.

6. The assembly of claim 5 , wherein each conduit comprises at least a portion that is a rigid material, a flexible material, an articulated portion, a flexible portion, or a combination thereof.

7. The assembly of claim 5 , wherein each conduit is positioned in fluid communication with a distributed cooling device.

8. The assembly of claim 1 , wherein the shared connector is positioned in fluid communication with a shared cooling device.

9. The assembly of claim 1 , wherein each transition connector is positioned in fluid communication with a fan.

10. The assembly of claim 1 , wherein the shared connector comprises at least a portion that is a rigid material, a flexible material, an articulated portion, a flexible portion, or a combination thereof.

11. The assembly of claim 1 , wherein each transition connector comprises at least a portion that is a rigid material, a flexible material, an articulated portion, a flexible portion, or a combination thereof.

12. The assembly of claim 1 , wherein the assembly comprises two primary cooling pathways and at least one partition forming two channels.

13. The assembly of claim 12 , wherein the assembly further comprises two secondary cooling pathways.
