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 th...
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 ...
