Abstract

A turbine containment system is provided. The turbine containment system includes a first containment member surrounding a portion of a turbine including a plurality of rotor disks and rotor blades; and a second containment member in communication with the first containment member, wherein the first containment member and the second containment member together contain each of the rotor disks and the rotor blades therein.

First claim

What is claimed is:

1 . A turbine containment system, comprising:
a first containment member surrounding a portion of a turbine including a plurality of rotor disks and rotor blades; and a second containment member in communication with the first containment member, wherein the first containment member and the second containment member together contain each of the rotor disks and the rotor blades therein.

2 . The turbine containment system of claim 1 , wherein the first containment member is an active clearance control casing in communication with the turbine.

3 . The turbine containment system of claim 2 , wherein the second containment member includes a Kevlar wrap disposed over a portion of the active clearance control casing.

4 . The turbine containment system of claim 3 , further comprising a shield including apertures on an interior surface of the shield, wherein the shield supports a portion of the second containment member.

5 . The turbine containment system of claim 4 , further comprising a cooling air source in communication with the active clearance control casing and the shield, wherein a first flow of cooling fluid from the cooling air source is directed through the active clearance control casing and the apertures of the shield to the turbine.

6 . The turbine containment system of claim 4 , wherein the apertures of the shield are positioned adjacent to the turbine in a radial direction.

7 . The turbine containment system of claim 4 , further comprising a spoke mount connection between the active clearance control casing and the second containment member to control thermal movement therebetween.

8 . The turbine containment system of claim 1 , wherein the first containment member surrounds the turbine along a longitudinal axis of the turbine containment system between a first end and a second end, and wherein a first thickness of the first containment member at the first end is different than a second thickness of the first containment member at the second end.

9 . The turbine containment system of claim 1 , wherein the second containment member is a soft wall hoop member attached under a core cowl portion of a turbine engine to the turbine containment system.

10 . The turbine containment system of claim 9 , wherein the soft wall hoop member is formed of an ultra-high-molecular-weight polyethylene material.

11 . The turbine containment system of claim 1 , further comprising a high temperature hard wall casing disposed over the first containment member.

12 . The turbine containment system of claim 11 , wherein the high temperature hard wall casing is formed of a titanium alloy material.

13 . The turbine containment system of claim 11 , wherein the high temperature hard wall casing is attached under a core cowl portion of a turbine engine to the turbine containment system.

14 . A turbine containment system, comprising:
a first containment member surrounding a portion of a turbine including a plurality of rotor disks and rotor blades; a second containment member in communication with the first containment member; and a shield including apertures on an interior surface of the shield, wherein the shield supports a portion of the second containment member, wherein the first containment member and the second containment member together contain each of the rotor disks and the rotor blades therein.

15 . The turbine containment system of claim 14 , further comprising a cooling air source in communication with the first containment member and the shield.

16 . The turbine containment system of claim 15 , wherein a first flow of cooling fluid from the cooling air source is directed through the first containment member and the apertures of the shield to the turbine.

17 . The turbine containment system of claim 14 , further comprising a spoke mount connection between the first containment member and the second containment member to control thermal movement therebetween.

18 . The turbine containment system of claim 14 , wherein the first containment member surrounds the turbine along a longitudinal axis of the turbine containment system between a first end and a second end, and wherein a first thickness of the first containment member at the first end is different than a second thickness of the first containment member at the second end.

19 . The turbine containment system of claim 14 , wherein the second containment member is a soft wall hoop member attached under a core cowl portion of a turbine engine to the turbine containment system.

20 . The turbine containment system of claim 14 , further comprising a high temperature hard wall casing disposed over the first containment member.
