Abstract

An apparatus is provided for an aircraft. This apparatus includes an electric machine (100A; 100B) and an air cooling circuit (134). The electric machine (100A; 100B) includes an electric machine rotor and an electric machine stator. The electric machine (100A; 100B) is configured to generate an electromagnetic field with the electric machine rotor and the electric machine stator. The electric machine rotor is configured to rotate about an axis (109A; 109B). The air cooling circuit (134) includes a cooling boot (142A; 142B). The air cooling circuit (134) is configured to direct air from an air source into the cooling boot (142A; 142B). The cooling boot (142A; 142B) forms an air plenum (166) with an exterior surface (174) of the electric machine (100A; 100B). The cooling boot (142A: 142B) includes a plurality of air outlets (178). The cooling boot (142A; 142B) is configured to direct the air through the air outlets (178) and into the air plenum (166) to air cool the electric machine (10A; 100B).
