Claim 12:
13. An air cycle machine comprising:
a turbine section comprising a turbine rotor;
a compressor section comprising a compressor rotor;
a ram air fan section comprising:
an integrally bladed rotor, and
a ram air scoop,
wherein the integrally bladed rotor comprises:
a rotor disk comprising a rim extending circumferentially about a center axis, wherein the rim comprises an interior rim surface and an exterior rim surface radially outward from the interior rim surface relative the center axis;
a rotor blade extending radially outward from the exterior rim surface of the integrally bladed rotor, wherein the rotor blade comprises:
a body extending from a leading edge to a trailing edge;
a pressure surface formed on the body and extending from the leading edge to the trailing edge; and
a suction surface formed on the body opposite of the pressure surface and extending from the leading edge to the trailing edge;

an internal channel inside of the body of the rotor blade and extending radially within the rotor blade; and
a plurality of air outlets formed proximate the leading edge of the rotor blade and extending into the body and fluidically connected to the internal channel; and

a tie rod connected to the turbine rotor, the compressor rotor, and the integrally bladed rotor.
