Abstract: Oil lubrication systems for use on gas turbine engines are described. The systems include a conduit and an air/oil separator connected to and arranged along the conduit. The air/oil separator comprises includes a housing and a semi-permeable divider within the housing, the semi-permeable divider being permeable to air but not oil. The semi-permeable divider separates a first flow path of an air/oil mixture and a second flow path of low pressure such that air from the air/oil mixture passes through the semi-permeable divider and is removed from the air/oil mixture, and wherein an air-to-oil ratio is less at the second end of the first flow path as compared to the air-to-oil ratio at the first end of the first flow path.
