Ported compressor with partially swept leading edge for gas turbine engine

A gas turbine engine, comprising:

• an inlet duct having a first outlet and a second outlet, the first outlet downstream from the second outlet;
• a port plenum having a port inlet in fluid communication with the second outlet of the inlet duct and a port outlet having a dimension;
• and
• an impeller including a hub, a shroud, and an impeller blade, the impeller blade extending for a span that is 0% at the hub and 100% at a tip, the shroud spaced apart from the tip, the impeller blade having a partially swept leading edge and extending in a streamwise direction from the partially swept leading edge to a trailing edge, the partially swept leading edge of the impeller blade in fluid communication with the first outlet, the port outlet defined through the shroud downstream of the partially swept leading edge in a direction of fluid flow through the impeller, and the partially swept leading edge extends in the streamwise direction at the tip upstream of the port outlet for a distance that is greater than the dimension.
