A cabin air compressor assembly that include a cabin air compressor disposed at a compressor inlet and a cabin air compressor motor operably connected to the cabin air compressor. At least one cooling flow inlet is configured to direct a cooling flow through various pathways in the cabin air compressor assembly, including across the cabin air compressor motor. A blower is configured to boost the cooling flow across the cabin air compressor motor, thereby increasing cooling flow provided to the air compressor motor. A static seal plate is downstream of the blower and guides the boosted cooling flow toward a cooling flow exit. In addition, the static seal plate isolates boosted cooling flow from a moving rotor of the cabin air compressor, and also forms part of a containment structure that contains fragments and breakage that may come from the cabin air compressor rotor.

1. An ECS comprising: a cooling gas inlet and a cooling gas exit connected by pathways, wherein a first pressure differential between said cooling gas inlet and said cooling gas exit is sufficient to draw cooling flow through at least one of said pathways at a flow rate;a movable blower disposed in said at least one of said pathways, wherein said movable blower is configured to apply a second pressure differential between said cooling gas inlet and said cooling gas exit, wherein said second presser differential is sufficient to boost said first pressure differential and boost said flow rate of said cooling flow to generate a boosted cooling flow downstream of said movable blower; anda static structure positioned downstream of said movable blower;wherein said blower directs said boosted cooling flow through said at least one of said pathways and along a surface of said static structure toward said cooling gas exit. 2. The ECS of claim 1 wherein said static structure further comprises a static seal plate. 3. The ECS of claim 1 further comprising: a cabin air compressor rotor; andwherein said static structure interferes with said boosted cooling flow impacting said cabin air compressor rotor. 4. The ECS of claim 1 wherein said blower comprises a plurality of blower blades. 5. The ECS of claim 1 further comprising said blower movably coupled to a compressor shaft. 6. The ECS of claim 1 further comprising: a cabin air compressor rotor; andsaid movable blower is separate from said air compressor rotor. 7. The ECS of claim 6 wherein said movable blower is constructed from a lighter material than said air compressor rotor. 8. The ECS of claim 1 further comprising: a cabin air compressor rotor; anda containment structure for said compressor rotor comprising said static structure. 9. The ECS of claim 8 wherein said movable blower is positioned upstream from said static structure such that said moveable blower does not interfere with how close said structure is to said compressor rotor. 10. The ECS of claim 9 wherein said containment structure further comprises a portion of said movable blower. 11. The ECS of claim 8, wherein said containment structure for said compressor rotor further comprises said movable blower.
